To access the CCU within a controller’s BIOS, type Ctrl/A to enter the BIOS during system startup, then select Container Configuration Utility from the main menu. To run the CCU from MS–DOS, execute the CCU program. This guide describes how to use the CCU running under MS–DOS. See the installation guide (included with your controller) for information on using the CCU within the BIOS. Unless otherwise noted, the CCU, as described within this guide, refers to the CCU for DOS. Interactive Versus Script Mode When used in MS–DOS mode (also known as interactive mode), the CCU offers the same interface and features as the BIOS version. You can use the CCU to create, display, and delete containers, as well as to initialize disk drives for use by the controller. See Chapter 2, Interactive Mode, for information on how to use the CCU’s interactive interface. In addition, the CCU offers a special command-line interface that enables you to create containers based on parameters specified in a plain-text script file. It also enables you to configure certain controller channel properties. You can record a controller’s current container and channel configuration in a plain-text script file, allowing you to easily restore your configuration or create a configuration based on a script ”template.“ See Chapter 3, Script Mode for information on how to use the CCU’s scripting features. 1-1 Adaptec SCSI RAID Container Configuration Utility User’s Guide Shared Channels You can use the CCU to enable or disable a channel as a shared channel. The CCU displays a shared channel in a different color than a nonshared channel. Running the CCU CCU.exe is normally distributed on a bootable floppy diskette. To run CCU from a bootable floppy, insert the diskette containing CCU.exe into your floppy disk drive and restart your system. (Be sure your system is configured to boot from drive A by default.) At the DOS prompt (A:\>), type the command CCU, followed by one or more optional command line switches, and press Enter. If you issue the command CCU without any command-line switches, the CCU displays its main window and awaits your menu selection (interactive mode). If you include any command-line switches with the CCU command, CCU processes your command with no further interaction (command-line or script mode). The remainder of this guide explains in detail how to use the CCU in both interactive and script modes. ❒ 1-2 Interactive Mode When you issue the CCU command at the DOS prompt without any command-line switches, the CCU displays its main window and waits for your menu selection. To select a CCU menu option, use the ↑ and ↓ keys to select an option, then press Enter. In some cases, selecting an option displays another menu. Press Tab to navigate between the fields within a dialog box. You can return to the previous menu at any time by clicking Esc. This chapter describes how to use the main options of the CCU. Creating a Container Before creating containers, make sure the drives to be used as members of the container are connected and installed in your server (or enclosure). Reboot your system if necessary to ensure that all connected drives are detected. To create a container, select the drive or drives to be used in the container, then assign the desired properties to the container. Selecting Partitions for the New Container To select one or more partitions to assign as members of the new container: 1 2 Use the ← and → arrow keys to select a channel. Use the ↑ and ↓ keys to select the drives to assign to the new container, then click Insert. The CCU displays the largest usable freespace available for each drive. You can use available freespace from multiple drives for the new container. 2-1 Adaptec SCSI RAID Container Configuration Utility User’s Guide To deselect a drive, highlight the drive and click Delete. Note that drives containing DOS partitions, drives with no available free space, or uninitialized drives (see Initializing a Disk Drive on page 2-6) appear dimmed and cannot be selected when creating a new container. 3 Click Enter when all partitions for the new container are selected. The CCU displays the Container Properties menu. Assigning Container Properties To assign various properties to the new container: 1 From the Container Properties menu, select a container type and click Enter. Note that only those container types available according to the number of drives selected are displayed. Table 2-1 describes the supported container types. Table 2-1. Supported Container Types Type Minimum Drives Volume 1 A container made up of one or more partitions concatenated together to form a single logical volume. RAID 0 (stripe set) 1 A container where data is striped across the partitions, allowing for faster I/O performance than a single disk drive or volume. Be aware that RAID 0 containers do not maintain any redundant data; if any disk drive in the container fails, all data is lost. RAID 1 (mirror set) 2 A container where data is mirrored on two equal-sized partitions that reside on two different disks. If one disk fails, data is available from the other disk. The actual capacity of the container equals half the available disk space. 2-2 Description Interactive Mode Table 2-1. Supported Container Types Type Minimum Drives RAID 5 3 A container with redundant (parity) data distributed across all partitions in the container. If any one disk fails, data can be reconstructed from the parity information. If a second disk fails before the container has been reconstructed, all data is lost. The actual usable data capacity of the container is equal to one less than the total number of partitions. (One partition’s worth of capacity is needed to hold the parity information.) RAID 10 (stripe of mirrors) 4 A container where parity data is striped across two or more mirror sets. If one disk in a pair fails, data is available. The actual data capacity of the container equals half the total available partition space. RAID 50 (stripe of RAID 5) 6 A container where data is striped across two or more sets of RAID 5 sets. Description Note: The number of drives used for each RAID level cannot exceed 32 drives. See the Command Line Interface Reference Guide for more information on considerations when selecting a RAID level. 2 3 4 Type in an optional label for the container and click Enter. Enter the desired container size. The maximum container size available based on the partitions you selected is displayed automatically. If you want to designate a different container size, type the desired container size and select MB (megabytes), GB (gigabytes), or TB (terabytes) from the dropdown list. If the available freespace from the selected partitions is greater than the size specified, the remaining freespace will be available for use in other containers. Select the desired container stripe size. Stripe size is the amount of data written to one partition in a stripe, RAID 5, 2-3 Adaptec SCSI RAID Container Configuration Utility User’s Guide RAID 10, or RAID 50 container before the I/0 data stream switches to the next partition. The allowable stripe sizes are 8, 16, 32 (the default), and 64 KBytes. For RAID 50 containers, 64 KBytes is the only stripe size allowed. The default stripe size gives the best overall performance in most network server environments. 5 Specify whether you want to enable read caching for the container. 6 Specify the write caching setting for the container. The possible values are as follows: • Disable—Disables use of the write cache. • Enable when protected—If supported, enables the write cache only when a battery is present and the battery’s charge status is OK. • Enable always—If supported, enables the write cache even if no battery is present or the battery’s charge status is not OK. Note that setting a container’s write cache property to Enable always might result in data loss or corruption if power to the controller is lost when no battery is present or the battery loses its charge. 7 When you are finished, click Done. Managing Containers Use the Manage Container option to view container properties, initialize containers, make a container the boot container, or delete containers. The following sections describe these operations in greater detail. Viewing Container Properties To view the properties of an existing container: 1 2 3 2-4 Select Manage Container from the Main menu. On the List of Containers dialog box, select the container you want to view information for, then click Enter. The Container Properties dialog box is displayed, which shows detailed information about the container. The physical disks associated with the container are displayed here, except Interactive Mode in the case of RAID 10 containers. For RAID 10 containers, highlight the displayed member and click Enter to display the physical disks associated with that member of the container. (Note that a failed drive is displayed in a different text color.) 4 Click Esc to return to the previous menu. Assigning Failover Drives To assign a failover drive to a container: 1 2 Select Manage Containers from the Main menu. On the List of Containers dialog box, select the container you want to assign a failover drive to, then click Ctrl/s. The Failover Management for Container dialog box is displayed, which shows the drives that can be assigned as failover drives. 3 Select a drive and click the Ins key to assign the drive as a failover. The specified drive is displayed in the Assigned failover drives list. 4 Click Enter to save the failover drive assignment. The following prompt is displayed: Have you finished managing failover drives? 5 Click Y (yes) to return to the Main menu. Removing Failover Drives To remove an assigned failover drive from a container: 1 2 3 Select Manage Containers from the Main menu. On the List of Containers dialog box, select the container you want to remove the assigned failover drive from, then click Ctrl/s. The Failover Management for Container dialog box is displayed, which shows a list of drives that can be assigned as failover drives, and a list of drives that are assigned as failover drives. From the Assigned failover drives list, select the drive to be removed, then click Del to remove the drive as a failover. The specified drive is displayed in the Select failover drives list. 2-5 Adaptec SCSI RAID Container Configuration Utility User’s Guide 4 Click Enter to save the removed failover drive assignment. The following prompt is displayed: Have you finished managing failover drives? 5 Click Y (yes) to return to the Main menu. Initializing a Disk Drive When you are creating a new container, if a disk drive is not listed in the disk selection list or if it is grayed out (not available), you must initialize the drive before you can use it as part of a container. ! Caution: Initializing a disk deletes all data on the disk. If the drive is a member of an existing container, you might not be able to use that container again. Do not initialize a disk that is part of a boot container. The boot container is numbered 00 in the List of Containers dialog box. See Viewing Container Properties on page 2-4 for information on determining which disks are associated with a particular container. To initialize a drive: 1 2 3 4 5 Select Initialize Drives from the Main menu. Use the ← and → arrow keys to select a channel. Select the disk you want to initialize, then click Insert. Click Enter. Read the warning message and ensure that you have selected the correct disk drives to initialize. Click Y to continue. Making a Container Bootable You can make a container bootable so the server boots from the container instead of from a stand-alone (single) disk drive. To make a container bootable: 1 Select Manage Container from the Main menu. 2 Select the container you want to make bootable, then click Ctrl/B. This changes the selected container’s number to 00, making it the controller’s boot container. 2-6 Interactive Mode 3 Reboot the system. If you are using SCSI disks, bear in mind the following behavior: ■ The server will always attempt to boot from any installed nonSCSI disks (for example, any IDE disk at drive C). You must disable or remove all non-SCSI disks if you want the server to boot from a SCSI disk or container. ■ You must back up the data on any SCSI disks that will be used as part of a container. Because disks must be initialized before they can be added to the array, the existing data will be lost if you do not back it up. ■ If containers already exist, a SCSI disk drive cannot be prioritized to be the primary booting drive. If there are no containers, you can set a SCSI drive to be the primary booting drive. However, if you subsequently create new containers, you cannot set any of these new containers to be the primary booting device. Deleting Containers To delete an existing container: ! 1 2 3 Caution: Be sure to back up the data on a container before you delete it. When you delete a container, all the data is lost. Select Manage Container from the Main menu. Select the container you want to delete, then click Delete. On the Container Properties dialog box, select Delete again, then click Enter. The following prompt is displayed: Warning!! Deleting will erase all data from the container. Do you still want to continue? (Yes/No): 4 Click Yes to delete the container, or No to return to the previous menu. 5 Click Esc to return to the previous menu. 2-7 Adaptec SCSI RAID Container Configuration Utility User’s Guide Hot-Swapping Adapters Hot-swaps are hardware replacements performed without removing power from the system. Hot-swapping adapters presents some conditions that you should consider. One way that a hot-swap differs from a cold-swap is the way the system recognizes the new hardware. In a cold-swap, BIOS detects the new hardware and requests a confirmation input. In a hot-swap, the system does not make an announcement or request any confirmation if it determines the changes are not risky. When performing a hot-swap, install the new adapter into the same slot occupied by the adapter you have just removed. Otherwise, the system will treat the new hardware as a new adapter, not as a replacement for the one you removed. ❒ 2-8 Script Mode To use the CCU scripting features, issue the command CCU with one of the following required switches: ■ /P—Playback mode. This mode configures containers and channel settings from a specified script file. ■ /R —Record mode. This mode saves a controller’s container and channel configuration in a specified script file for later playback. On the CCU command line, you can also specify the name of a log file to record the status of the playback or record operation. The CCU records in the log any errors or warnings encountered. When running the CCU in playback or record mode, the utility stores the status of the playback or record operation in the DOS variable ERRORLEVEL on exit, allowing it to be used within a DOS batch file. See Error Handling on page 3-19 for more information on error handling. Table 3-1 lists the required and optional CCU command-line switches. 3-1 Adaptec SCSI RAID Container Configuration Utility User’s Guide Table 3-1. Command-Line Switches Switch Description /P Indicates playback mode. In this mode, the CCU reads the contents of the specified script file and creates containers and configures channel settings based on the properties defined in the script. The is the name of the script file. It can include a drive, directory, and file name and extension, but only the file name and extension (.CCU) are required. If no drive is specified, the current default drive is used. If no directory is specified, the current default directory is used. Note that the CCU exits with an error if you do not include either the /P or /R switch (but not both) on the command line. /R Indicates record mode. In this mode, the CCU scans the controller’s current container and channel configuration and creates the specified script file based on the configuration. The is the name of the script file. It can include a drive, directory, and file name and extension, but only the file name and extension (.MLC) are required. If no drive is specified, the current default drive is used. If no directory is specified, the current default directory is used. Note that the CCU exits with an error if you do not include either the /P or /R switch (but not both) on the command line. 3-2 Script Mode Table 3-1. Command-Line Switches Switch Description /L Optional log file name. If you include this switch, the CCU records its activity, and any errors it encounters, in the log file. If no /L switch is specified, the CCU displays any status and errors on the screen. The is a standard DOS file, which can include a drive, directory, file name and extension. Only the file name and extension (.LOG) are required. If no drive is specified, the current default drive is used. If no directory is specified, the current default directory is used. /C Optional controller number. In systems with more than one controller, this switch specifies the controller on which to operate. Controllers are numbered from 0 to number of controllers minus 1. If no /C switch is specified, controller 0 is used. Note that the number assigned to a particular controller is dependent on the controller’s physical PCI slot and the order in which your system scans its PCI slots. Playback Mode Playback mode enables you to create one or more containers based on the properties defined in a script file. It also enables you to configure certain properties for each channel on the controller. When you create a container, you can specify any of the properties listed in Table 3-2. 3-3 Adaptec SCSI RAID Container Configuration Utility User’s Guide Table 3-2. Container Properties Property Description Type The container type. The following container types are supported: ■ Volume set ■ RAID 0 (stripe) set ■ RAID 1 (mirror) set ■ RAID 5 set ■ RAID 10 (stripe of mirrors) set ■ RAID 50 (stripe of RAID 5) set Size The size of the container to be created. Size can be specified in megabyte (MB), gigabyte (GB), or terabyte (TB) units, or Maximum to specify the maximum size based on the given type and disks. Label An alphanumeric string uniquely identifying the container. StripeSize The size, in Kbytes, of contiguous data distributed across a “striped” container (RAID 0, RAID 5, RAID 10, or RAID 50). Cache settings The cache settings of the container. You can specify the following values for the caches: ■ ReadCache—Yes (enable), or No (disable) ■ WriteCache—One of the following values: -Yes—Enable when protected -No—Disable -Always—Enable always Drives The disk drives to use in creating the container. Drives are identified by their channel number, ID number, and logical unit number (LUN). FailoverDrives The disk drives to assign as failover drives for this container. Drives are identified by their channel number, ID number, and LUN. In addition, there are other container properties that enable you to control the various container settings during creation. See Container Definition Block Properties on page 3-9 for the complete list of container properties. 3-4 Script Mode Note that you can configure each individual channel on the controller using the ControllerID property, which specifies the SCSI ID number of the controller on the channel Initializing Drives By default, when you use playback mode to create containers, the CCU initializes only those drives specified by the Drives property keywords within the script file. It does this initialization step before creating any new containers. For example, if your script file defines two new containers, the first a RAID 1 (mirror) container with the property Drives=0:0:0, 1:0:0 and the second a RAID 5 container with the property Drives=0:1:0, 0:2:0, 0:3:0, the CCU initializes all five of the drives comprising the two containers before creating any containers. Any other drives connected to the controller are not affected. Initializing a drive automatically deletes any existing containers with that drive as their member. For example, if you specify drive 0:0:0 in a container’s Drives property and that drive happens to be part of a RAID 0 (stripe) container, the CCU deletes the stripe container when it initializes the drive. Note that existing containers with drive members that are not specified in any Drives property within the script are not affected. In some cases, you might want the CCU to initialize all drives connected to the controller, even those that are not specified in a script’s Drives property. This ensures that all drives are initialized and any existing containers are deleted before any new containers are created. You can specify InitializeAll=Yes within any container definition to instruct the CCU to do this. Unlike most container properties, the InitializeAll=Yes property is a global CCU setting and does not apply only to the container whose definition it appears in. Therefore, you need only specify InitializeAll=Yes once, within any container definition, to produce the desired action. Because the CCU reads the entire script file before creating any containers, the position of the InitializeAll=Yes property within the script is not significant. Continuing the previous example, if the InitializeAll=Yes property is specified in the second RAID 5 container’s definition, the CCU initializes all drives before creating the first RAID 0 container. 3-5 Adaptec SCSI RAID Container Configuration Utility User’s Guide Note that any container scrub in progress when a container is deleted will automatically be terminated. See Container Definition Block Properties on page 3-9 for details on the syntax of the InitializeAll property. Record Mode Record mode writes an existing controller’s container configuration to a specified script file, enabling you to create the same configuration by running the CCU in playback mode with the resulting script. In addition, record mode records certain controller properties that can be set in playback mode. Because the CCU supports only a subset of container types available through the CLI and GUI, it cannot record all the possible container configurations. If the CCU encounters a container that it cannot create itself—for example, a volume of mirrors container—it displays a warning (and records the warning in its log file, if that switch is used) and does not record any properties for that container in its script file. The script file is limited to one controller and its associated container configuration files. Although you can have multiple controllers on a single system, you cannot record all of the controllers and their associated container configurations in one file. To record multiple controllers, use the CCU record mode once for each individual controller. Your end result will be multiple files on the same diskette, with one file corresponding to each controller. Determining Scrub/Clear Status When using playback mode to create a container, you can specify whether to wait for a container’s initial scrub or clear to complete or to continue while the scrub or clear proceeds in the background. (See the Wait container property in Table 3-2 on page 3-4.) If you instruct the CCU to continue (Wait=No), you need to be able to check the status of a background scrub or clear task and determine when it is complete. The CCU provides a way to do this. When you use record mode to record a controller’s configuration and you specify a log file (/L switch), the CCU writes to the log scrub and clear status information about each container in the configuration. An application or batch 3-6 Script Mode file can then parse the resultant log file to determine whether a container’s scrub or clear is complete, in progress (a percentage of the task is complete), or failed. The following example shows a log file of a recorded configuration consisting of three containers: Reading container information ...Passed Scanning for Drives ...Passed Reading cache values...Passed Container #0 Status : OK Container #1 Status : SCRUB 30% Container #2 Status : SCRUB/CLEAR FAILED Each status line consists of the prefix Container # Status :, where is the container ID, followed by the status. The possible status values are as follows: ■ OK Indicates a nonredundant container (no scrub required) or a redundant container whose scrub task completed successfully. ■ SCRUB % CLEAR % Indicates a scrub (or clear) is currently in progress, where is the percentage of the operation that is complete. The percentage is an integer between 0 and 99, inclusive. ■ SCRUB/CLEAR FAILED Indicates a scrub or clear that did not complete due to a data error or other unexpected problem. When a scrub task runs on a multilevel container, the scrubbing occurs on the child containers and not on the parent container. Consequently, the parent task always indicates 0% and the child task indicates 0% to 100%. When a clear task runs on a multilevel container, the clearing occurs on the parent container and not on the child containers. Consequently, the parent task indicates 0% to 100% and the child tasks always indicates 0%. 3-7 Adaptec SCSI RAID Container Configuration Utility User’s Guide Scrub Operations on RAID 10 Containers RAID 10 containers can be created by scrubbing only. For a RAID 10 container, the status message indicates the percent of the scrub completed for the parent and child tasks. The status updates to OK when the tasks complete. A sample RAID 10 scrub status is as follows: Container #1 Status : PARENT = SCRUB 0%, CHILD = SCRUB = 30% Scrub Operations on RAID 50 Containers RAID 50 containers can be created by scrubbing only. For a RAID 50 container, the status message indicates the percent of the scrub completed for the parent and child tasks. The status updates to OK when the tasks completes. A sample RAID 50 scrub status is as follows: Container #1 Status : PARENT = SCRUB 0%, CHILD = SCRUB = 30% Script File Syntax A CCU script file consists of one of the following: ■ Container definition block—Specifies the properties of a container, such as type, size, and cache settings. The block begins with the keyword Container and ends with the keyword End. ■ Channel definition block—Specifies the properties of a controller channel, such as ControllerID. The block begins with the keyword Channel and ends with the keyword End. Each container or channel property consists of a property keyword and assigned value, separated by an equal sign (=). Each property must be on its own line in the script. The order of properties within a block (other than the starting Container or Channel keyword, and the ending End keyword) is not significant. Some container properties, such as Type, are required, whereas others are optional. Table 3-3 lists which properties are optional and what default value is used when that property is not specified. All keywords can be written in any combination of upper- or lowercase characters. Script lines can include any number of spaces 3-8 Script Mode and tabs both within keywords, or when separating keywords and their values. Blank lines are ignored. The pound character (#) indicates the start of a comment. The CCU ignores all characters on a line that begins with a pound sign. You can use comments following container property assignments, or on their own lines. See Example on page 3-22 to see a sample script that includes comments. Container Definition Block Properties Table 3-3 lists the properties that can be specified within a container definition block. The table lists each property’s keyword, whether it is required, and its default value (if any). Note that the keywords are arranged so the required keywords are listed first. Table 3-3. Container Definition Block Properties Keyword Required? Default Value Description Container Yes None Indicates the start of a container definition block. See page 3-12 for more information. Drives Yes None Specifies the disk drives used in creating the container. See page 3-12 for more information. Type Yes None Indicates the type of container to create. See page 3-12 for more information. 3-9 Adaptec SCSI RAID Container Configuration Utility User’s Guide Table 3-3. Container Definition Block Properties Keyword Required? Default Value Description End Yes None Indicates the end of a container definition block. See page 3-13 for more information. FailoverDrives No None Specifies the failover drives to assign to this container. See page 3-13 for more information. InitializeAll No No Indicates whether to initialize all the drives connected to the controller. See page 3-14 for more information. Method No Scrub Indicates which method (scrub or clear) to use when creating a RAID 5 container. See page 3-15 for more information. ReadCache No Yes Indicates whether read caching is enabled for this container. See page 3-15 for more information. 3-10 Script Mode Table 3-3. Container Definition Block Properties Keyword Required? Default Value Description Size No Maximum Specifies the size of the container. See page 3-16 for more information. StripeSize No 32 Specifies the size of contiguous I/O, in bytes. See page 3-16 for more information. Wait No Yes Indicates whether the CCU should wait for the new container’s scrub or clear to complete before continuing. See page 3-17 for more information. WaitForScrub No Yes Is provided for backward compatibility only. See page 3-17 for more information. WriteCache No Yes Indicates whether write caching is enabled for this container. See page 3-17 for more information. The following sections describe each of these keywords in detail. 3-11 Adaptec SCSI RAID Container Configuration Utility User’s Guide The Container Keyword The Container keyword indicates the start of a container definition block. It accepts an optional container label value. This keyword is required. Examples: Container Container=MyData The Drives Keyword The Drives keyword specifies the disk drives to use in creating the container. This property is required; there is no default value. A drive is identified by its channel number, ID (target), and LUN, separated by colons. For example, 0:0:0 or 1:2:0. Separate multiple drive identifiers with commas. Note: Any drive specified within the script file will first be initialized, destroying any data on that drive. If a drive is specified in more than one container definition block in a script, it will be initialized only once. Examples: Drives=0:0:0 Drives=0:0:0,0:1:0,0:2:0 The Type Keyword The Type keyword indicates the type of container to create. This keyword is required; there is no default value. The possible values are as follows: ■ Volume—Volume (JBOD) set ■ RAID 0—RAID 0 (stripe) set ■ RAID 1—RAID 1 (mirror) set ■ RAID 5—RAID-5 set 3-12 Script Mode ■ RAID 10—RAID 10 (stripe of mirrors) set ■ RAID 50—RAID 50 (stripe of RAID 5) set The minimum number of disk drives required to create each type of container is as follows: ■ Volume—1 ■ RAID 0—1 ■ RAID 1—2 ■ RAID 5—3 ■ RAID 10—4 ■ RAID 50—6 Examples: Type=Volume Type=RAID1 Note: The number of drives used for each RAID level cannot exceed 32 drives (16 drives for RAID 5). The End Keyword The End keyword indicates the end of a container definition block. This keyword is required. Example: End The FailoverDrives Keyword The FailoverDrives keyword specifies the failover drives to assign to this container. Failover drives are specified in the same way as the Drives property. The FailoverDrives property is optional; if not specified, no failover drives are assigned to this container. 3-13 Adaptec SCSI RAID Container Configuration Utility User’s Guide Note the following: ■ When assigning failover drives to a RAID 10 container, the CCU assigns all the drives in the list to all the mirror set containers within the RAID 10 container. ■ The CCU makes no checks to ensure that the amount of freespace on the specified failover drives is sufficient to serve as failover for the given container. Example: FailoverDrives=1:0:0,1:1:0 The InitializeAll Keyword The InitializeAll keyword indicates that all the drives connected to the controller should be initialized, and any existing containers deleted, before creating a new container. This property applies to all drives on all channels of the controller. The possible values are as follows: ■ Yes—Initialize all drives. ■ No—Do not initialize all drives; only those drives specified with the Drives property keyword are initialized. The InitializeAll property is optional; if it is not specified, the value No is used. The InitializeAll keyword is both global and positionindependent within a script file. If InitializeAll=Yes appears in any container definition block within the file, all drives connected to the controller are initialized and any existing containers are deleted before any new containers (defined within the script) are created. If there is no InitializeAll=Yes property specified anywhere in the script, the CCU initializes only those drives specified with the Drives property keyword. See Initializing a Disk Drive on page 2-6 for more details. Note that it is not necessary to specify InitializeAll=Yes in more than one container definition block. If both InitializeAll=Yes and InitializeAll=No are specified 3-14 Script Mode within a script file, regardless of their position within the file, InitializeAll=Yes is the overriding value. Examples: InitializeAll=Yes InitializeAll=No The Method Keyword The Method keyword indicates which method to use when creating a RAID 5 container. The possible values are as follows: ■ Scrub—Scrub the container. ■ Clear—Clear the container. Overall, the Scrub method takes longer than Clear, but it enables you to begin using the container immediately. The Clear method, although faster, must complete before you can begin using the container. The Method property is optional; if not specified, then the value Scrub is used. Note that the Method property applies only to RAID 5 containers. Other redundant container types (RAID 1 and RAID 10) always use the scrub method. The CCU ignores any Method property within the definition block of any container type other than RAID 5. Examples: Method=Scrub WaitForClear=No The ReadCache Keyword The ReadCache keyword indicates whether this container uses read caching. The possible values are as follows: ■ Yes—Enable read caching. ■ No—Disable read caching. 3-15 Adaptec SCSI RAID Container Configuration Utility User’s Guide If no ReadCache property is specified, the value Yes is used. Example: ReadCache=Yes The Size Keyword The Size keyword specifies the size of the container. Specify the size as an integer or a decimal number, followed by the unit keyword MB (megabytes), GB (gigabytes), or TB (terabytes). A unit keyword is required with a numeric size value. If no unit keyword is specified, the CCU exits with an error. Specify the keyword Maximum to create a container using the maximum available space, based on the container type and drives selected. If no Size property is specified, the value Maximum is used. Examples: Size=2.5GB Size=300MB Size=Maximum The StripeSize Keyword The StripeSize keyword specifies the size of contiguous I/O, in Kbytes, written to each member of a striped container before switching to the next member. This property applies only to container types RAID 0, RAID 5, RAID 50, and RAID 10. The CCU exits with an error if this property is specified for any other container types. The possible values for StripeSize are 8, 16, 32, and 64. Do not specify a unit keyword for the stripe size because all values are in Kbytes. If no StripeSize property is specified and the container type supports this property, the value 32 is used by default. Example: StripeSize=64 3-16 Script Mode The Wait Keyword The Wait keyword indicates whether the CCU should wait for the new container's scrub or clear to complete before continuing. The Wait property is optional; if not specified, the CCU waits for the container’s scrub or clear to complete before continuing. Specify Wait=No to allow the CCU to continue while the scrub or clear completes in the background.1 Examples: Wait=Yes Wait=No The WaitForScrub Keyword The WaitForScrub keyword is provided for backward compatibility only. Use the Wait keyword instead. The WaitForScrub keyword is still recognized and can be used interchangeably with the Wait keyword. The WriteCache Keyword The WriteCache keyword indicates whether write caching is used for this container. The possible values are as follows: 1 ■ Yes—Enable the write cache if the cache is protected by a battery and the battery’s status is OK. ■ No—Disable the write cache. ■ Always—Enable the write cache even if no battery is present, or the battery’s status is not OK. Container scrubs and clears are tasks executed entirely on the controller, and do not depend on the CCU or any other host application to complete. If the controller is powered off before the scrub or clear completes and is then restarted, the scrub or clear task resumes without any user intervention. 3-17 Adaptec SCSI RAID Container Configuration Utility User’s Guide Note: Setting a container’s WriteCache property to Always might result in data loss or corruption if power to the controller is lost when no battery is present or the battery loses its charge. If no WriteCache property is specified, the value Yes is used. Examples: WriteCache=Yes WriteCache=Always Channel Definition Block Properties Table 3-4 lists the properties that you can specify within a channel definition block. The table lists each property’s keyword and a description of the property. Note that channel properties, unlike container properties, have no default values. If a Channel property keyword is not specified, the corresponding controller setting for that channel is not changed. Similarly, if no channel definition block is specified for a channel, the current controller settings for that channel are not changed. Table 3-4. Channel Definition Block Properties Keyword Description Channel Specifies the channel number to which the channel properties apply. This keyword begins a channel definition block. Buses are numbered from zero to the maximum number of channels on the controller minus one. You can include multiple channel definition blocks within a script file, each beginning with a Channel keyword and value. Example: Channel=0 End Indicates the end of a channel definition block. Example: End 3-18 Script Mode Table 3-4. Channel Definition Block Properties ControllerID Specifies the SCSI ID of the controller on the channel. Normally, the controller is assigned SCSI ID 7 on each of its channels. You can specify any ID value between 0 and 15. If you do not specify a ControllerID keyword for the channel, the channel’s current controller ID setting is not changed. Example: ControllerID=15 Error Handling Because the CCU scripting feature is designed to run without user interaction, the CCU handles error during record and playback by simply exiting immediately whenever an error is detected. Whenever the CCU encounters an error during record or playback— for example, an unrecognized keyword in a script file—it reports the error and exits. If a log file is opened (see Running the CCU on page 1-2), the CCU writes the error message to the log file. Otherwise, it displays the message on the screen. Upon exit, the CCU returns its exit status (zero for success or a nonzero error code associated with an error) in the DOS environment variable ERRORLEVEL. When the CCU is run within a DOS batch file, that batch file can examine the CCU’s exit status using the DOS command IF ERRORLEVEL n. The batch file can use this command to test the CCU success or failure status. The batch file can test for a specific error using a series of If ERRORLEVEL n commands. Table 3-5 lists the possible status codes returned by the CCU. Table 3-5. Error Codes Code Error/Information Meaning 0 You ran CCU and made no changes. This exit code indicates success (that is, the CCU exited with no errors) and that no report is required. 1 No Controller Found. The CCU did not detect any controllers in the system. 3-19 Adaptec SCSI RAID Container Configuration Utility User’s Guide Table 3-5. Error Codes Code Error/Information Meaning 2 Syntax or logical error in the script file. The CCU encountered an invalid command or keyword in the specified script file. 3 Unable to open file. The CCU was unable to open the specified script or log file. 4 Error in the command line parameters. You passed an invalid command-line switch to the CCU. (See Script Mode on page 3-1 for the list of valid command switches.) 5 Unable to read system configuration. The CCU was unable to get the configuration information from the specified controller. 6 No drives detected. The CCU did not detect any disk drives attached to the selected controller. 7 Specified drive not found in system. The disk drive you specified does not exist on the selected controller. 8 Specified container size too small. You specified a container size that is smaller than the minimum size allowed for this container. 9 Specified container size too big. You specified a container size that is larger than the maximum size allowed for this container. 10 Number of drives do not match the container type. The number of drives you selected is invalid for the type of container specified. 11 Unable to initialize drive. The CCU was unable to initialize one or more disk drives. 12 Error occurred while creating container. The CCU encountered an error creating a container. 13 Too many failover drives assigned. You attempted to assign more than the maximum number of failover drives allowed for the specified container. 14 Insufficient memory to run the application. There is not enough memory to run the CCU. 15 Incorrect controller number. The controller number you specified is invalid or out-of-range. 3-20 Script Mode Table 3-5. Error Codes Code Error/Information Meaning 16 Controller not responding. The controller has stopped responding to the CCU. 17 Scrub/Clear failed The scrub or clear running on one or more containers has failed. 100 You ran CCU and made changes. The exit code indicates success (that is, CCU exited with no errors) and that a reboot is required. Playback and Record Notes When using CCU in playback or record mode: ■ When recording a container, the CCU does not create a Wait keyword within a container’s definition block in a script file. When playing back any script file generated from the CCU record option, be aware that the CCU will use the default setting Wait=Yes when creating a container unless you first edit the script file and include a Wait=No line in the container’s definition block. ■ When recording a RAID 10 (stripe of mirrors) container, the CCU cannot map failover drives assigned to the individual mirror set containers to the FailoverDrives list in the resultant script file; the script file syntax allows only a single list of failover drives to be assigned to any given container. In this case, the CCU creates the FailoverDrives list using all the drives assigned to the lower-level mirror set containers within the RAID 10 container. When playing back this script, the CCU assigns all the drives in the FailoverDrives list to all the mirror set containers making up the RAID 10 container. However, this might not exactly match the original failover drive assignments to the mirror set containers. ■ When recording a container, the CCU creates a separate channel definition block for each channel on the controller. Each block includes all the property keywords and values reflecting the channel’s current settings. Edit the script file as necessary to change any of the channel’s settings or delete 3-21 Adaptec SCSI RAID Container Configuration Utility User’s Guide keywords to ensure the controller’s corresponding channel setting is not changed. Example The following DOS command invokes the CCU and creates containers on controller 1 based on the container properties defined in the script file A:\RAID.CCU. It also configures the properties of channel 0 and saves a log of the operation in the log file C:\RAID.LOG. A:\> CCU /P A:\RAID.CCU /L C:\RAID.LOG /C1 The following example is the RAID.CCU script file used in the previous CCU command. This script creates three containers—a 500MB, single-disk volume container; a 2GB, two-drive RAID 1 (mirror) container; and a “maximum size”, three-drive RAID 5 container—and sets the properties of channel 0. # Script to create volume, mirror, and # RAID-5 containers # Create a 500MB volume set labeled # ‘MySystem’ Container=MySystem Type=Volume Size=500MB Drives=0:0:0 # Assign drive 1:0:0 as the failover drive. FailoverDrives=1:0:0 End # Create a 2GB mirror set labeled ‘MyMirror’ Container=MyMirror Type=RAID1 Size=2GB #Use drives on channels 0 and 1 Drives=0:1:0,1:1:0 3-22 Script Mode # Disable write cache WriteCache=No #Assign 2 failover drives FailoverDrives=1:2:0, 1:3:0 End # Create a maximum size RAID 5 set labeled # ‘MyData’ Container=MyData Type=RAID5 Size=Maximum # Use the maximum stripe size StripeSize=64 # Clear the container (don’t scrub it) Method=Clear #Don’t wait for clear to complete Wait=No #Use drives 2, 3, 4 on channel 0 Drives=0:2:0, 0:3:0, 0:4:0 #Assign failover drives FailoverDrives=1:1:0,1:2:0 End # Set Channel 0 properties Channel=0 3-23 Adaptec SCSI RAID Container Configuration Utility User’s Guide # Set the controller’s SCSI ID to 7 ControllerID=7 End ❒ 3-24
