This utility allows the user to: • Create and manage arrays • Monitor system status • Manage spares • Configure the controller • Manage disk drives and enclosures Starting the Disk Array Administrator Utility NOTES: Microsoft® Windows® 3.x and Windows® NT™ 3.5x include a program called Terminal which does not support ANSI color. If using either O/S, select VT-100 for terminal emulation or use a third-party software program such as Procomm for Windows. Microsoft® Windows® 95/98/NT/2000 includes a program called HyperTerminal that supports ANSI color. The Disk Array Administrator Utility is implemented with a VT-100 or ANSI terminal connected through the RS-232 serial port on the RAID Module (Figure 2). This utility is embedded in the firmware; software loading is not required unless for upgrade purposes. The Disk Array Administrator Utility can also be implemented through the RS-232 serial port on the InfoStation User Interface Module (InfoStation Firmware Rev. 1.6 and higher), as shown in Figure 7. This is especially convenient in rack-mount environments where it may be difficult to access the InfoStation RAID Module directly. RS-232 Serial Port IFS_6a Figure 7: InfoStation User Interface Module StorCase Technology, Inc. S10C100 User's Guide - Rev.

S10C100 User's Guide - Rev. A01 Configuration 17 Creating and Managing Arrays and Partitions Using the Disk Array Administrator, the user can create and manage arrays and partitions. The following array-related functions can be performed: • Create arrays • Manage arrays • Manage partitions Creating Arrays NOTE: Before creating more than one array, make sure that the host operating system supports multiple LUNs. Most operating systems do, or have an option to enable multiple LUN support. If the host system does not support multiple LUNs, the host will only see one array at LUN 0. An array can be created at anytime. Table 4 below describes the drive requirements for each RAID level. Table 4: Drive Requirements for each RAID Level RAID Level Min. # of Drives Max. # of Drives 0 2 15 3 3 15 4 3 15 5 3 15 50 6 30 Mirrored 2 15 Volume Set 1 1 IFS_56FC Before an array is created, the user must decide whether or not to partition the array. There are two (2) ways to partition an array: 1. Single-partition array - an array that stores all data in a single partition and is accessed by a single LUN. 2. Multiple-partition array - an array that can have one or more partitions, with each partition assigned its own LUN. Refer to section "Understanding Partitions" for further information. S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 18 Configuration Creating a Single-Partition Array This function allows the user to create single-partition arrays. Once a single-partition array has been created, more partitions can be added later. Single-partition arrays work well in environments that need one large, fault-tolerant storage space for data on one server. To create a single-partition array: 1. Select Add an Array from the System Menu and press Enter. The Enter Array Name screen should now display (Figure 10). Figure 10: Enter Array Name Screen 2. Enter a name for the array and press Enter. Up to 35 characters (any character, including spaces) can be used. If no name is to be used, just press Enter (a name may be added or changed later). The system will now ask if you want to create one partition for the entire array. 3. Select Yes to create a single-partition array and press Enter (for creating multiplepartition arrays, refer to section "Creating a Multiple-Partition Array" for further information). The LUN screen should now display (Figure 11). The LUN displayed is the suggested default LUN assignment. StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 19 Figure 11: Array LUN Screen 4. Select the LUN for the array and press Enter. If the letters OV appear before a LUN, this indicates that the selection overlaps with a soft LUN, most likely the controller or SAF-TE Environmental Processor (SEP) LUN. An array at an overlapped LUN may be created, but it will not be seen by the host system until the controller is rebooted. NOTE: Most UNIX, LINUX, and Macintosh operating systems require the controller LUN to be a higher value than all array LUNs. Before creating the first array, change the controller LUN to a higher value or choose NONE (best option) if not using CAPI to manage the arrays. This allows the first array to be seen at LUN 0. The system will now warn you about the LUN for UNIX and Macintosh (see notes above), the first time an array is created. Press Enter and the system will ask if you want to be warned again. Select No to avoid receiving this warning again (otherwise, select Yes to be warned the next time an array is created). The RAID Type screen should now display (Figure 12). S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 20 Configuration Figure 11: Array LUN Screen Figure 12: RAID Type Screen 5. NOTE: Select the array type (RAID0, RAID3, RAID4, RAID5, RAID50, Volume, or Mirrored) and press Enter. A RAID 10 array is created when there are more than two (2) drives in a mirrored array. If RAID 50 is selected as the RAID type, the Select RAID 50 Array Size screen displays all possible configurations for the array and drive combinations. Select the desired configuration and press Enter. Skip to Step 7. For all other RAID types, the Number of Drives screen will display (Figure 13). StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 21 Figure 13: Number of Drives Screen 6. Enter the number of drives (excluding spares) to be used in the array and press Enter. The Select Drives screen should now display (Figure 14). Figure 14: Select Drives Screen 7. Select the drives to be used for the array and press Enter. A drive is selected by highlighting it and then pressing Enter. Each selected drive turns gray in the drive list. To skip a drive, use the é or ê key. If the array is mirrored, RAID 3, RAID 4, RAID 5, or RAID 50 and there are one or more drives left, the Number of Spares screen will display. S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 22 8. Configuration If the Number of Spares screen displays, enter the number of spares to add and press Enter. This creates dedicated spares that can only be used in this array. A dedicated spare drive will not be available for any other use (refer to section "Managing Spares" for further information). If no spare is desired, simply enter 0. The Select Drives screen should now display (Figure 14). 9. Select the drive to be used as a dedicated spare and press Enter. NOTES: Only available drives (drives that aren't members of an array and are not assigned as dedicated or pool spares) will be displayed. A drive is selected by highlighting it and then pressing Enter. Each selected drive turns gray in the drive list. To skip a drive, use the é or ê key. A dedicated spare can be deleted from the array at any time (refer to section "Deleting a Dedicated Spare" for further information). If the array created is RAID 3, RAID 4, RAID 5, or RAID 50, the Chunk Size screen will display (Figure 15). Figure 15: Chunk Size Screen StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 10. 23 Select the chunk size and press Enter. The chunk size is the amount of contiguous data that is written to an array member before moving to the next member of the array. To determine the appropriate chunk size, refer to the operating system's documentation (for example, the default chunk size for Windows NT and many other operating systems is 64KB). The system will now confirm your request to create the array. 11. Select Yes and press Enter. A message will notify you that the array is being created and will show the progress of the initialization process. The array initialization process takes from several minutes to more than an hour depending on the array type (RAID 0, RAID 1, and Volume are the quickest), array size, drive speed, and other processes running the controller. Press Esc to return to the Disk Array Administrator Utility and perform other functions. To check the progress of the array initialization, select Array Menu from the System Menu. The status of the initialization will display in the list of arrays. The array initialization process can be stopped (refer to section "Stopping the Array Initialization Process" for further information). NOTE: Most operating systems (such as Windows NT 4.0) require the host system to be rebooted to see the new array. NetWare v3.45 (and later) can recognize new devices by typing the command SCAN FOR NEW DEVICES at the console prompt. Other operating systems might have similar features. S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 24 Configuration Creating a Multiple-Partition Array This function allows the user to create multiple-partition arrays. Multiple-partition arrays work well with very large disk drives and make the most efficient use of disk space for fault tolerance (parity and spares). Refer to section "Understanding Partitions" for further information. To create a multiple-partition array: 1. Select Add an Array from the System Menu and press Enter. The Enter Array Name screen should now display (Figure 10). 2. Enter a name for the array and press Enter. Up to 35 characters (any character, including spaces) can be used. If no name is to be used, just press Enter (a name may be added or changed later). The system will now ask if you want to create one partition for the entire array. 3. Select No to create a multiple-partition array and press Enter. The RAID Type screen should now display (Figure 12). 4. NOTE: Select the array type (RAID0, RAID3, RAID4, RAID5, RAID50, VOLUME, or MIRRORED) and press Enter. A RAID 10 array is created when there are more than two drives in a mirrored array. If RAID 50 is selected as the RAID type, the Select RAID 50 Array Size screen displays all possible configurations for the array and drive combinations. Select the desired configuration and press Enter. Skip to Step 7. For all other RAID types, the Number of Drives screen will display (Figure 13). 5. Enter the number of drives (excluding spares) to be used in the array and press Enter. The Select Drives screen should now display (Figure 14). 6. Select the drives to be used for the array and press Enter. A drive is selected by highlighting it and then pressing Enter. Each selected drive turns gray in the drive list. To skip a drive, use the é or ê key. If the array is mirrored, RAID 3, RAID 4, RAID 5, or RAID 50 and there are one or more drives left, the Number of Spares screen will display. StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 7. 25 Enter the number of spares to be added and press Enter. This creates dedicated spares that can only be used in this array. A dedicated spare drive will not be available for any other use (refer to section "Managing Spares" for further information). If no spare is desired, simply enter 0. The Select Drives screen should now display (Figure 14). 8. Select the drive to be used as a dedicated spare and press Enter. NOTES: Only available drives (drives that aren't members of an array and are not assigned as dedicated or pool spares) will be displayed. A drive is selected by highlighting it and then pressing Enter. Each selected drive turns gray in the drive list. To skip a drive, use the é or ê key. A dedicated spare can be deleted from the array at any time (refer to section "Deleting a Dedicated Spare" for further information). If the array created is RAID 3, RAID 4, RAID 5, or RAID 50, the Chunk Size screen will display (Figure 15). 9. Select the chunk size and press Enter. The chunk size is the amount of contiguous data that is written to an array member before moving to the next member of the array.

Reconstructing an Array The controller automatically reconstructs redundant arrays (RAID 3, RAID 4, RAID 5, RAID 50, and Mirrored) if an array becomes critical and if a spare drive (with enough space) is available. An array becomes critical when one or more member drives fail. If a reconstruct does not start automatically, it is because there are no valid spares available. To start a reconstruct, replace the failed drive and add it as a spare (refer to sections "Adding a Dedicated Spare" and "Enabling Dynamic Spares" for further information). NOTE: Any pool spares added may be used by any critical array, and not necessarily by the intended array. StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 37 Expanding Array Capacity (OCE) Online Capacity Expansion (OCE) allows the user to expand the arrays without having to stop I/O activity. Only one array can be expanded at a time, and the expansion of the array must be completed before expanding another array. NOTES: Expanding an array does not change the size of the host operating system partitions that reside on the array (the controller only works at the block level, not at the file system level of the operating system). To use the new space, a new partition must be created (using the newly added space) or a third-party application (specific to the operating system) must be used to change the partition size. The OCE function may take an hour or more to complete, depending on the array type, array size, drive speed, and other processes running the controller. Once an OCE has started, it cannot be aborted! The number of drives that can be added to an array depends upon the RAID level. Table 5: OCE Drive Additions by RAID Level RAID Level # of Drives that can be Added RAID 0 1-4 RAID 1 Does not support OCE RAID 3, 4, or 5 1-4 RAID 10 2 or 4 RAID 50 3-5 Volume Set Does not support OCE IFS_55FC To expand multiple-partition arrays, free space is added at the end of the array (refer to section "Understanding Partitions" for further information).

Select Yes and press Enter. Trusting an Array This function allows the user to bring an array back online by resynchronizing the time/date stamp and any other metadata on a bad disk. This will make the disk an active member of the array again. Use this function whenever: • One or more disks of an array start up more slowly or were powered ON after the rest of the disks in the array. This will cause the time/date stamps to differ, which the controller will interpret as a problem with the "late" disks. In such a case, the array will function normally after using the Trust Array function. • An array is offline because a drive is failing, there is no data backup, and the user is attempting to recover data from the array. In such a case, the Trust Array function may work but only as long as the failing drive continues to operate. Before using this function, it must be enabled in the Option Configuration Menu (default setting is DISABLED). CAUTION: The Trust Array function can cause unstable operation and data loss if used improperly! This feature is intended for disaster recovery only! To trust an array: 1. Select Configuration Menu from the System Menu and press Enter. The Configuration Menu should now display (Figure 38). 2. Select Option Configuration and press Enter.

If the array does not come back online, it may be because there are too many members offline. Or, it may be because the array may have additional failures on the bus (or enclosure) that the Trust Array option cannot fix. Deleting an Array This function allows the user to delete an array when the array is no longer needed or when the drives are needed for another use. CAUTION: NOTE: Deleting an array will delete all partitions and data stored in that array! Before reusing the drives, performing a low-level format on each drive is recommended. An array cannot be deleted while any utility (Initialize, Verify, Expand, or Reconstruct) is running on the array. The utility must be stopped (if possible) or completed before the array can be deleted. To delete an array: 1. Select Delete an Array from the System Menu and press Enter. The Select Array screen should now display (Figure 16). 2. Select the array to be deleted and press Enter. The system will now confirm your request to delete the array. 3. Select Yes and press Enter. StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 43 Managing Partitions The Disk Array Administrator software allows the user to manage partitions, including: • View partition status information • Add a partition • Expand a partition • Change a partition name • Change a partition LUN • Set up LUN zoning • Delete a partition Understanding Partitions When an array is created, the array can either be all one partition or it can be set up with multiplepartitions. Using multiple-partitions, allows the user to create one very large array (making efficient use of the drives). For example, one very large RAID 5 array can be created with one dedicated spare assigned to the array. This minimizes the amount of disk space allocated to parity and spares (compared to the disk space required for 5-6 smaller RAID 5 arrays). Once an array is set up for multiple-partitions, the user must create each partition by setting the partition size and assigning the partition a LUN. It is recommended that each partition be assigned a name that will indicate how each partition will be used (for example, if the first partition is used to store a customer database, name it "cust data base"). When a multiple-partition array is first created, all the space on the array is designated as free space (Figure 28). Free Space IFS_76 Figure 28: Array Set-up for Partitions Before Creating Partitions S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 44 Configuration When a partition is created, the user must specify the size (in MB) of the partition (Figure 29). Partition 1 Free Space IFS_77 Figure 29: Array after Creating One Partition The Disk Array Administrator assigns each partition a unique serial number and sequence number. Sequence numbers are assigned in the order the partitions are created. Once one or more partitions are created on an array, additional partitions may be created in the remaining free space or a partition may be expanded (with some limitations). A partition can only be expanded into contiguous, free space following the partition. After all of the free space has been partitioned, the partition can only be expanded by deleting a partition that follows (the next highest in sequence) the partition to be expanded. In Figure 30, partition 3 can be deleted so that partition 2 can be expanded to use some or all of partition 3's space. CAUTION: Deleting a partition also deletes all data stored in that partition! Be sure to back up all data before deleting a partition! Partition 1 Partition 2 Partition 3 Partition 4 Partition 5 IFS_78 Figure 30: Array after Creating Five Partitions When expanding an array, free space is added at the end of the array as shown in Figure 31 (refer to section "Expanding Array Capacity" for further information).

A01 Configuration 55 Working with LUN Zoning The controller's LUN zoning capability allows the user to specify which servers (hosts) can access each partition. This gives the user complete control of array access based on specific needs. Before setting up LUN zoning, the user should know the World Wide Name (WWN) for each server to be set up (the system SAN administrator should know the WWNs for the network). A list of the last 16 WWNs can be displayed by the controller. Each WWN can be given a name, making LUN zoning faster and easier to work with. LUN zoning is set up by either excluding or including servers on a list for each partition LUN. The list can include or exclude up to 16 specific servers or all servers for each partition LUN.

Partition 1 has an include list that contains only Accounting (meaning only Accounting can access Partition 1). Array B has three partitions; Partition 3 has an exclude list that contains only the Web Server (meaning all servers can access Partition 3, except the Web Server). Array C is a single-partition array and uses the default setting "Include All Hosts" (meaning all servers can access the array). S10C100 User's Guide - Rev.

The controller will be aware of any server that was booted since the controller was last restarted. Typically, servers will scan for devices during the device discovery process. During this process, the controller will save the WWN information for the server and retains the information even after the controller is rebooted. The list includes the last 16 servers (either booted or named). The user can determine each server's WWN by booting one server at a time and then viewing the WWN list. The most recently booted server will be listed first. To make LUN zoning easier To make LUN zoning easier to manage, it is recommended that each server be given an easily recognizable name (alias).

A01 StorCase Technology, Inc. 78 Configuration Managing Spares The controller will automatically reconstruct redundant (fault-tolerant) arrays (RAID 3, RAID 4, RAID 5, and RAID 50, and Mirrored) if an array becomes critical (and a sufficiently-sized spare drive is available). An array becomes critical when one or more member drives fail. The user can set up two (2) types of spare drives: • Dedicated - Available drive that is assigned to a specific array. • Pool - Available drive that is assigned to the pool, which can provide a spare for any failed drive in any redundant array. In addition, if the Dynamic Spares option is enabled and a drive fails, the drive can be replaced and the controller will rescan the bus; it will then find the new disk drive and automatically start reconstruction of the array. The controller will look for a dedicated spare first. If it does not find a sufficiently-sized dedicated spare, it will then look for a pool spare. If a reconstruct does not start automatically, it means that there are no valid spares available. To start a reconstruct, the user must: 1. Replace the failed drive, if no other drive is available. 2. Add the new drive or another available drive as a dedicated spare to the array (or as a pool spare). NOTE: Any pool spares added may be used by any critical array, and not necessarily by the intended array. Managing Dedicated Spares Dedicated spares are unused disk drives that are assigned to a specific array. The disk must be as large as the smallest member in the array. A dedicated spare drive cannot be used in an array, nor as a pool spare. Although using a dedicated spare is the most secure way of providing a spare for an array, it is not very cost-effective keeping an idle drive assigned to the array. An alternative method is to assign one or more idle drives to the spare pool (refer to section "Managing the Spare Pool" for further information). StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 79 Adding a Dedicated Spare This function allows the user to add dedicated spares to a specific array. If a member drive in the array fails, the controller will use a dedicated spare drive to automatically reconstruct the array. The user can add dedicated spares to Mirrored (RAID 1 and RAID 10) and parity (RAID 3, RAID 4, RAID 5, and RAID 50) arrays at anytime. Up to four (4) dedicated spare drives can be added to an array (refer to section "Creating Arrays" for further information). NOTES: A spare cannot be added unless it has enough capacity to replace the smallest member in the array. If a drive was a member of an array and was removed from the array, it cannot be used as a spare until all the metadata is cleared from the drive (refer to section "ClearingMetadata from a Drive" for further information). To add a dedicated spare: 1. Select Array Menu from the System Menu and press Enter. The Select Array screen will display, along with a list of existing arrays (Figure 16). 2. Select the desired array and press Enter. The Array Menu should now display (Figure 17). 3. Select Add Spare and press Enter. The List of Available Drives screen should now display. 4. Select the drive to add as a spare and press Enter. The system will confirm your request to add the spare. 5. Select Yes and press Enter. S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 80 Configuration Deleting a Dedicated Spare This function allows the user to delete a dedicated spare drive from an array at anytime. To delete a dedicated spare: 1. Select Array Menu from the System Menu and press Enter. The Select Array screen will display, along with a list of existing arrays (Figure 16). 2. Select the desired array and press Enter. The Array Menu should now display (Figure 17). 3. Select Delete Spare and press Enter. The List of Available Drives screen should now display. 4. Select the drive to delete as a spare and press Enter. The system will confirm your request to delete the spare. 5. Select Yes and press Enter. Enabling Dynamic Spares This function allows the user to use all of the disk drives in redundant arrays, without assigning one as a spare. For example, if the Dynamic Spares option is enabled and a drive fails, the drive can be replaced and the controller will rescan the bus; it will then find the new disk drive and automatically start reconstruction of the array. With the Dynamic Spares option enabled, the controller will first look for a dedicated (or a pool spare, if no dedicated drives are available) drive for reconstruction (if spares or drives are available). NOTES: The spare or available drive must have enough capacity to replace the smallest member in the array, otherwise the controller cannot use it. Make sure the spare or available drive does not contain any metadata (refer to section "Clearing Metadata from a Drive" for further information). Performance in systems without a SAF-TE Processor Board will decrease if an array becomes critical (with this option enabled) and there are no available drives to start a reconstruct. To minimize performance impact, increase the rescan rate. StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 81 To enable dynamic spares: 1. Select Configuration Menu from the System Menu and press Enter. The Configuration Menu should now display (Figure 38). 2. Select Option Configuration and press Enter.

The Rescan Rate screen should now display. This tells the controller how often it should look for an available drive by rescanning the bus. Rescanning the bus frequently can affect performance. The system will confirm the rescan rate. 6. Select Yes and press Enter. Managing the Spare Pool The spare pool allows the user to have one or more disk drives available for the reconstruction of redundant arrays (Mirrored and Parity). Once a drive is assigned to the spare pool, it is no longer available for use as an array member or as a dedicated spare. If a pool spare is too small (not enough capacity to replace the smallest member in the array), the controller cannot use it. StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 83 Adding a Spare to the Spare Pool This function allows the user to add up to eight (8) drives to the spare pool to reconstruct any critical array on the controller. After an array has started using a pool spare, other critical arrays are prevented from using it. If a pool spare is too small (not enough capacity to replace the smallest member in the array), the controller cannot use it. To add a pool spare: 1.

Table 6: Host Channel Settings Host Channel Setting Available Modes Enable/Disable Stand-Alone Single Port Do not disable the host channel when in Single Port mode. Stand-Alone Dual Port OK to disable a host channel when planning on shutting down the host on that channel. All modes, but only when using Loop topology FC Loop ID: The user may need to change the FC Loop ID if the controller needs to be at a specific address or if the system checks addresses in reverse order (lower address first). Target ID Description There are two options: SOFT: Use this setting if it does not matter whether the controller’s Loop ID changes everytime during power UP/DOWN. This setting lets the FC loop initialization process determine the Loop ID. Any number between 0-125: Select a specific number if the Loop ID is to remain the same during power UP/DOWN. The Disk Array Administrator Utility cannot tell the user which Loop IDs are available. To be sure that the specified Loop ID was successfully assigned, check the Loop ID after rebooting the controller. If the controller cannot get the specified Loop ID during the loop initialization process, it will try to get a soft address instead. Topology All modes Topology: Be sure that the controller’s topology setting is correct for the configuration. The topology can be set to: Loop: Use this option for all configurations except when the controller is connected to a switch F-port. Point-to-Point: Use this option when connecting the controller to a switch F-port. Auto Detection: Automatically detects the configuration based on the loop initialization process or port address of switch or fabric. Use this option when unsure of the topology used or when planning to change the configuration (ie. during testing of the controller). IFS_82 StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Configuration 91 Table 6: Host Channel Settings (cont'd) Host Channel Setting Available Modes Description Controller LUN All The controller has just one LUN that the user can change when configuring the host channels.

S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 92 Configuration Understanding LUNs and Viewing LUN Information The controller supports up to 64 SCSI LUNs numbered 0-63. There are three (3) different types of LUNs: controller, SEP, and partition. The user can view information about each LUN (refer to section "Viewing LUN Information" for further information). Controller LUN - The user only needs to assign a controller LUN if using the Configuration Application Program Interface (CAPI) to configure the controller over a host channel via SCSI protocol extensions. If not using CAPI, the user can set the controller LUN to NONE. If using CAPI, the user can set it to a value of 0-63. NOTE: Most UNIX, LINUX, and Macintosh operating systems require the controller LUN to be a higher value than all array LUNs. Before creating the first array, change the controller LUN to a higher value or choose NONE (best option) if not using CAPI to manage the arrays. This allows the first array to be seen at LUN 0. SEP LUNs - Allow access to SEPs. An SEP LUN may be set to a value of 0-63 or NONE. NONE means that the SEP cannot be accessed via a LUN (refer to section "Changing the SEP LUN" for further information). Partition LUNs - Allow access to partitions on the controller. Partition LUNs may be set to any numeric value from 0-63 (refer to section "Changing a Partition LUN" for further information). StorCase Technology, Inc. S10C100 User's Guide - Rev.

A01 Configuration 105 Changing the Utility Priority This function allows the user to change the priority at which all utilities (Verify, Reconstruct, Expand, Initialize, etc.) run when there are active I/O operations competing for the controller's CPU. The choices are: • High (Default) • Medium • Low For example, select High if the highest priority is to get the array back to a fully fault-tolerant state. This causes heavy I/O with the host to be slower than normal. Select Low if streaming data without interruption (such as for a Web server), is more important than data redundancy. This allows the Reconstruct (or other utility) to run at a slower rate, with minimal effects on the host I/O. To change the utility priority: 1. Select Configuration Menu from the System Menu and press Enter. The Configuration Menu should now display (Figure 38). 2. Select Utility Priority and press Enter. The Utility Priority screen will display (Figure 72). The current setting is marked with an * next to it. Figure 72: Utility Priority Screen 3. Select the desired option and press Enter. S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 106 Configuration Rescanning All Channels This function allows the user to scan all disk channels for new or removed disk drives. The rescan will temporarily pause all I/O processes (normal operation will resume once rescan is complete). If using an InfoStation with the SAF-TE Board installed, the controller will perform a rescan automatically. With the SAF-TE Board, the controller will detect removed drives almost immediately; installed drives will be detected after a 3 minute delay (to allow for drives to spin up). NOTE: If installing a new drive, wait for the drive to spin up before rescanning the channels. This will avoid unnecessary delays during the rescan that can cause the operating system to time-out. To rescan all channels: 1. Select Utilities Menu from the System Menu and press Enter. The Utilities Menu should now display (Figure 47). 2. Select Rescan and press Enter. Pausing I/O The function allows the user to suspend activity on all device channels used in the controller, thereby ensuring data integrity on the connected drives and arrays.

S10C100 User's Guide - Rev. A01 Appendix B - Array Basics 129 Appendix B - Array Basics The InfoStation RAID Controller Module allows the set up and management of disk arrays. A disk array is a group of disks that appears to the system as a single virtual disk. This is accomplished through software contained in the RAID controller. RAID (Redundant Array of Independent Disks) refers to disk arrays in which part of the array storage capacity may be used to store redundant information. The redundant information allows the restoration of user data if a disk in the array fails. The host system views the controller as a single SCSI disk drive. It is actually an array of physical disks behind a RAID controller (It is managed by software to appear as a single physical disk). Depending on the array type, the virtual disk has advantages in fault-tolerance, cost, performance, or a combination of these. Array Types Array types are defined by their RAID level, a number from 0 through 5 (a higher RAID level does not necessarily indicate a higher level of performance or fault-tolerance). The RAID Module allows the user to create the types of arrays proven to be the most useful for RAID applications: RAID 0, 1, 0/1 (also known as mirrored or RAID 10), 3, 4, 5, and Volume Sets. RAID 0 (Striped Disks) In a RAID 0 array, data is distributed (also known as striped) across the disks in the array. The array appears to the server as one large disk with a capacity approximately equal to the combined capacity of the physical disks. Because multiple reads and writes can be handled in parallel, the input/output performance of the array is much better than that of a single physical disk. RAID 0 arrays do not store redundant data, so they are not true RAID applications. If one disk fails, the entire array fails and all array data is lost. The fault-tolerance of a RAID 0 is less than that of any single disk in the array. The term RAID 0 is widely used for these arrays however, because they are conceptually similar to true RAID applications. S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 130 Appendix B - Array Basics RAID 1, 0/1, and 10 (Mirrored Disks) In RAID 1, RAID 0/1, and RAID 10 arrays (commonly referred to as mirrored arrays), disks are paired, with both disks in the pair containing the same data. When data is written to a mirrored array, it is written twice - once to each disk in the pair. A RAID 1 array has only one set of paired disks. A RAID 10 array has multiple pairs, across which data is striped. The read performance of RAID 1 arrays can be much greater than that of a single disk, while the write performance is slightly lower. In RAID 1/10 arrays, both read performance and write performance are better than those of a single disk. A mirrored array is also highly reliable, because both disks in the pair must fail for the array to fail. For example, an array of five pairs can still maintain integrity even if five disks fail, as long as each pair is left with one good disk. The main disadvantage of a mirrored array is cost. Since all disks must have a twin, twice the number of disks must be used in the array capacity (an eight-disk array contains only four disks of usable capacity). RAID 3 RAID 3 arrays contain redundant information in the form of parity data, which is calculated block-by-block for all user data. The user data is distributed across all but one of the disks in the array. The parity data is written exclusively to the parity disk (also known as check disk). In the even of a disk failure, the data can be reconstructed from corresponding data stripes on the remaining disk in the array. RAID 3 provides excellent I/O performance for applications that require high data transfer rates such as image processing, video processing, scientific data collection, batch data processing, or sequential reads and writes. RAID 4 RAID 4 is similar to RAID 3 in that redundant information is achieved in the form of parity data. The user data is distributed across all but one of the disks and uses a single, dedicated parity disk for data protection. The main difference is that RAID 3 usually synchronizes writes to its disks, while RAID 4 can send data to its disk independently. RAID 4 is best suited for transaction processing applications that require high speed read requests. RAID 4 is not recommended for I/O intensive applications that require high speed data transfer rates. StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Appendix B - Array Basics 131 RAID 5 RAID 5 arrays contain redundant information in the form of parity data, which is calculated block-by-block for all user data. The parity information is distributed across the disks in the array (similar to RAID 0 arrays) and occupies the equivalent capacity of about one disk. Data is interspersed with the parity information. If one disk in the array fails, the data on the failed disk can be reconstructed from the parity data and user data on the remaining disks. Two disks must fail before the entire array fails. The read performance of a RAID 5 array is excellent, comparable to that of a RAID 0 array. Write performance is lower than that of a RAID 0 array, because write operation involves calculating and writing new parity data as well as writing the new user data. RAID 50 RAID 50 arrays contain redundant information in the form of parity data, which is calculated block-by-block for all user data. The partity information is distributed across the disks in the array and occupies the equivalent capacity of approximately one disk. Data is interspersed with the parity information. If one disk in the array fails, the data on the failed disk can be reconstructed from the parity data and user data on the remaining disks. Two disks must fail before the entire array fails. The read performance of a RAID 5 array is excellent - comparable to that of a RAID 0 array. Write performance is lower than that of a RAID 0 array, because write operations involve calculating and writing new parity data, as well as writing the new user data. Volume Sets A volume set is a host-accessible LUN that maps to a single disk in the array, similar to JBOD. Volume sets are non-redundant and have a capacity slightly less than the physical disk they are created from. Volume sets are useful if a single disk is available and not used as a spare. Mixing Disks from Different Manufacturers or with Different Capacities An array can contain different models of SCSI disks, even disks with different capacities (an array can include a 4GB disk and a 9GB disk). However, if disks with different capacities are mixed, the logical capacity of all other disks in the array is determined by the smallest disk (regardless of RAID level). To maximize disk capacity, use disks of similar size. S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 132 Appendix B - Array Basics Mixing Disks on Different RAID Controller Channels The RAID Controller Module hasfour drive channels. An array can consist of disks on different channels of the same RAID controller. Comparing RAID Levels Table B-1 illustrates the differences between the various RAID levels.

Terminal Emulator and COM Port Problems • Screen continuously puts out garbage characters. The likely cause is a baud rate mismatch between the terminal emulator and the RAID Controller Module. The correct baud rate is 115,200. Check to make sure the terminal emulator is set to the correct baud rate. NOTE: 1. Some terminal emulators do not immediately change to the new baud rate settings. Exit and restart the emulator to use the new settings. If possible, shut down the controller (refer to section "Rebooting the Controller" for further information). If unable to shut down controller, continue with Step 2. 2. Turn OFF power to the InfoStation chassis. 3. Hold down the spacebar (on the keyboard) and turn ON power to InfoStation chassis. This will allow the controller to autodetect the baud rate setting. 4. Select option 5 from the Flash Utility to continue rebooting the controller. • Nothing is displayed on the terminal emulator. The probable cause is either a bad RS-232 cable connection or a bad cable. Ensure that the cable is connected properly. Check the cable for any damage. If attempting to access the RAID Module via the InfoStation UI Module's RS-232 serial port, ensure that serial port set-up was done correctly (refer to section "Starting the Disk Array Administrator Utility" for further information. Ensure that the correct InfoStation Firmware is being used (Firmware Rev. 1.6 or higher). StorCase Technology, Inc. S10C100 User's Guide - Rev. A01 Appendix C - Troubleshooting • 135 Screen is updated, but won't respond to keystrokes. Disable hardware flow control on the terminal or terminal emulator. The RAID Controller Module supports XON/XOFF flow control and works properly in most cases with no flow control. • Screen looks correct, but clock is not updated. Check to make sure that the InfoStation is still powered on. If using XON/XOFF, press Ctrl-Q. • Screen is updated and menus appear correct, but boxes around menus look incorrect. Try a different font in the terminal emulator program. If a correct font cannot be found, set ASCII display to "Yes" in the Display option of the Configuration Menu (Figure 38). • The host system does not see the controller. Press CTRL-E and verify that there is a valid Host Channel FC World Wide Name (WWN). Verify that the port ID is active and a valid Arbitrated Loop Port Address (AL_PA) is assigned. Verify that the array LUN numbers are configured correctly and not overlapping. Array Problems • Array is much smaller than it should be. The backoff percentage may be set higher than 1%, which is causing the array to be much smaller than the full size of its member disks. The backoff percentage reduces the capacity of the array by the given percentage. The backoff percentage helps when assigning spares by compensating for the minor capacity differences that occur between drive manufacturers. It allows the user to work with drives of the same nominal capacity, but with dfferent actual capacities (for example, two 18GB drives from different manufacturers may differ in capacity by 100MB). The default setting is 1% backoff. Once set, the backoff percentage affects all arrays created on the controller. S10C100 User's Guide - Rev. A01 StorCase Technology, Inc. 136 NOTE: Appendix C - Troubleshooting A backoff percent of 1% is strongly recommended. To change the backoff percentage: 1. Select Configuration Menu from the System Menu and press Enter. The Configuration Menu should now display (Figure 38). 2. Select Backoff Percent and press Enter. The Backoff Percent screen should now display. 3. Enter the desired backoff percent and press Enter. The percentage is entered as a 3-digit number, using the following format - 00.0% (default is 01.0%). Device SCSI Channel Problems • Not all drives connected to the device channels are displayed during boot, or the RAID Controller Module hangs during display of connected drives and never reaches the Administrator Utility screen. Check the InfoStation to make sure it is properly configured for use with the RAID Controller Module . Check to make sure all the InfoStation drive carriers are properly installed. Check termination and ID assignment. Or, try reducing the maximum drive channel speed. If there are drives that are not Ultra160 capable, try setting the bus speed to 80MB/sec.
