Chapter 1. Overview
1.1 Your Tape Drive The X1500 and X800 XenData Digital Archive Systems include an external LTO SAS tape drive manufactured by Hewlett Packard: XenData System X1500 X800
Included Tape Drive Type LTO-5 LTO-4
Compatible Cartridge Max. Capacity 1.5 TB 800 GB
1.2 About LTO Linear Tape Open (LTO) is the leading data tape format and uses technology developed by HP, IBM and Quantum Corporation. The latest generation of LTO is LTO-5 which provides high storage capacity, high speed file transfers and a long archival data life:
Huge storage capacity Each tape cartridge stores 1.5 TB without any compression. For video files, this represents over 65 hours at a 50 Mbits/s recording rate. High speed file transfers LTO-5 tape drives write to and read from tape at up to 140 MBytes/s. Long archival data life LTO tape cartridges are available from multiple manufacturers that specify a 30 years archival data life.
LTO tape cartridges are available as rewritable or WORM. WORM is an acronym for Write Once Read Many and the data written to WORM LTO tape cartridges cannot be altered. This means that WORM tapes cannot be reformatted and reused, unlike rewritable cartridges. Tape drive compatibilities are as follows. Drive Type LTO-5 LTO-4

1.3 About Barcodes and Tape Labels A label may be attached to an LTO tape cartridge. This can be a paper label with a descriptive volume label which may be hand-written or it can be a barcode label as shown below.
When using a tape library, barcodes labels are the preferred method for keeping track of tapes, as most tape libraries include a barcode reader. However stand-alone tape drives do not have the capability of reading barcode labels but they are able to read the in-cartridge memory chip that is present in all LTO tape cartridges. When an LTO tape having a barcode label is formatted in a tape library under control of XenData server software, the software writes the barcode information to the in-cartridge memory chip which allows the barcode information to be read in a stand-alone tape drive and to be displayed by XenData6 Workstation software.

Chapter 2. Tape Drive Operation 2.1 Tape Drive Front View
1. Tape Cartridge Door 2. On/Off Switch 3. Encryption LED (LTO-5 drive only) 4. Clean LED 5. Tape LED 6. Drive LED 7. Ready LED 8 Eject Button
2.2 Powering on the Tape Drive Immediately after powering on the tape drive, it will run its hardware self-test which takes about 5 seconds. If the selftest passes, the green Ready LED flashes and then shows steady green. If the test fails, the Drive Error and Tape Error LEDs flash, while the Ready and Clean LEDs are off.
2.3 Removing Power from the Drive To ensure reliable operation, do not remove power from the drive during read, write, fast search, load and unload activities. It is especially important to avoid removing power when files are being written to a tape cartridge. This may put the tape cartridge into a ‘protected state’ which will prevent further files being written to that tape.

2.4 Loading a Tape Cartridge 2.4.1. Lift the cartridge door and insert the cartridge into the slot in the front of the drive with the arrow uppermost and facing the drive door.
1. Arrow indicated insertion direction. 2. Tape cartridge door. 3. Tape cartridge label area.
2.4.1 Apply gentle pressure until the drive takes the cartridge and loads it. 2.4.3 The Ready LED flashes green while the drive performs its load sequence. When the cartridge is loaded, the Ready LED shows steady green.
2.5 Ejecting a Tape Cartridge 2.5.1 Wait until the system has completed all read and write operations.
2.5.2 Press the eject button on the front panel of the tape drive or use XenData6 Workstation to initiate an eject command.
1. Eject Button
2.5.3 The tape drive will rewind the tape to the beginning and eject the cartridge. This may take several minutes. The Ready LED will flash to indicate that the unload process is still in progress.

2.6 Tape Drive Cleaning The tape drive does not require regular cleaning. A Universal LTO Cleaning Cartridge should only be used when the orange Clean LED is flashing. To clean the tape drive:
Load the LTO Universal Cleaning Cartridge into the drive. The drive will carry out its cleaning cycle and eject the cartridge on completion (which can take up to 5 minutes). During the cleaning cycle the orange Clean LED will be on solidly and the green Ready LED will flash.
Each LTO Universal Cleaning Cartridge can be used up to 50 times with LTO tape drives. If the cleaning cartridge is ejected immediately with the Tape LED on, it has expired.

Chapter 3. LED Sequence Diagnostics
LED Sequence
Cause
Action Required Make sure the drive is switched on. The power on/off switch incorporates a green LED.
All LED’s OFF.
Drive may not have power, may be faulty or may have been power cycled or reset during a firmware upgrade.
Check the power cord connection and replace the cable if necessary. On external drives, you can use the power cord from your monitor or another device to check that the connection is working. If the power supply is present and all LEDs remain off, power cycle or reset the drive. If it still fails, call for service.
Ready and Clean OFF. Drive and Tape FLASH.
Power cycle or reset the drive. The drive has failed to execute power-on self test (POST).
If the error condition reappears, call for service.
The drive is ready for operation.
None. This is normal.
Ready is ON.
Ready FLASHES.
None. The drive is carrying out a normal activity (read, write).
Ready FLASHES fast.
The drive is downloading firmware.
Firmware is being reprogrammed.
Ready FLASHES and Clean is ON.

Do not reset or power cycle the drive.
Do not reset or power cycle the drive.
The drive requires cleaning.

Ready is OFF, others are ON.
If the drive is upgrading firmware, do not reset or power cycle it.
Load the Universal LTO Cleaning Cartridge. If the Clean LED is still flashing when you load a new or known good data cartridge after cleaning, call for service.
None. The cleaning cartridge will eject on completion. Cleaning is in progress. The cleaning cycle can take up to 5 minutes to complete.

The tape is ejected immediately and Tape FLASHES, Drive FLASHES on unloading tape.
Drive FLASHES.
Drive, Tape and Ready FLASH.

The drive believes the tape just ejected is incompatible.
The drive believes the current tape or the tape just ejected is faulty.
The tape cartridge memory (CM) may be faulty.
The drive mechanism has detected an error.
Check compatibility of the ejected tape. For example using an LTO-2 or LTO-1 tape in an LTO-5 drive would cause this behavior.
Unload the tape cartridge. Make sure that you are using the correct format cartridge; or a Universal Cleaning Cartridge. Reload the cartridge. If the Tape LED still flashes or starts flashing during the next attempt, load a new or known good cartridge.
Write protect the cartridge by sliding the switch on the tape cartridge. The tape can be loaded and the data read. Once the data is recovered, the cartridge must be discarded.
Load a new cartridge. If the error persists, power cycle or reset the drive. If the Drive LED remains on, call for service.
There is a firmware download problem.
Insert a cartridge to clear the LED sequence. If the condition persists, call for service.
Power cycle or reset the drive. The drive has a firmware error.
Upgrade the firmware. If the condition persists, call for service.
