[. . . ] You can use the power cable 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. This is normal. All LEDs OFF. Ready is ON. The drive is ready for operation. See "Running HP OBDR" on page 52 for further details. then Ready FLASHES- steady ON- FLASHES. See "Cleaning cartridges" on page 48 for supported cartridges and instructions. If the Clean LED is still flashing when you load a new or known good data cartridge after cleaning, call for service. The cleaning cycle can take up to 5 minutes to complete. Cleaning is in progress. The drive believes the current tape or the tape just ejected is faulty. Tape FLASHES. Unload the tape cartridge. (See "Use the correct media" on page 47. ) Reload the cartridge. If the Tape LED still flashes or starts flashing during the next backup, load a new or known good cartridge. If the Tape LED is now off, discard the 'suspect' tape cartridge. If it is still on, call for service. DAT SCSI Tape Drives 43 LED Sequence Cause The drive mechanism has detected an error. Action required Load a new cartridge. If the condition persists, call for service. Drive FLASHES. There is a firmware download problem. Drive, Tape and Ready FLASH. LED sequences for the HP StorageWorks DAT 72 and DAT 40 tape drive There are two LEDs, labeled Tape and Clean. The meaning of different patterns of LEDs is as follows: Tape LED on flashing slowly flashing rapidly off or flashing Clean LED off off off on Meaning The cartridge is loaded and the drive is ready. HP StorageWorks DAT drives perform a comprehensive self-test during power-up. If a hard error causes the self-test to fail, the clean light changes to steady amber. Wait for the current operation to finish, then insert a different tape and repeat the operation that was being performed. If the media caution signal does not show this time, it indicates that the original cartridge was nearing the end of its useful life. Copy any data you want to keep from the original tape onto a new tape if possible, then discard the old tape. If the media caution signal appears again with the second tape, the tape heads need cleaning. If the media caution signal appears after using a cleaning cartridge, the cleaning cartridge has probably expired and should be discarded. [. . . ] (Always use an LVD-rated cable and an LVD-rated or multimode terminator. ) Figure 29 SCSI termination in daisy-chained external drives Removable drives For HP StorageWorks DAT removable tape drives, termination is provided by connecting a terminator to the spare SCSI connector on the rear of the tape array. If you have each removable drive in the tape array attached to a separate bus, then, for each bay in use, you must attach a terminator to the spare connector for each device. If you are using the removable drives to mirror backups, you can daisy-chain devices (but no more than two on each SCSI bus). Connect an LVD-rated cable from the spare SCSI connector for the first DAT SCSI Tape Drives 67 device to one of the SCSI connectors for the second device and attach the terminator to the spare SCSI connector for the second device.
