HP StorageWorks Ultrium Full-Height SCSI Tape Drives User Guide (EH853-90905, August 2007)

Has the drive been moved recently? Have any cables been disconnected and reconnected? Has the
environment changed—unusually hot, cold, damp or dry? Has there been dust or dirt near the drive.
Have reasonable precautions against static been taken?
The problem could lie with the drive:
1. Check the cables and connectors.
2. Clean the tape heads with the cleaning cartridge.
3. If the problem persists, check the environmental conditions against the specied lim its, see table
above or refer to h
ttp://www.hp.com. Perhaps move the drive to a m ore suitable site.
Has a new operating system been installed in the host computer? Has new backup software b een
installed?
The problem could lie with the host or the software. Consult the com puter’s operating ma nuals, the
software manual, or seek help from a service engineer.
Problems with cartridges
If you experience any problems using HP branded cartridges, check:
The cartrid
ge case is intact a nd that it contains no splits, cracks or damage.
The c artridge has been stored at the correct temperature and humidity. This prevents
condensation. See the insert included with the tape cartridge for storage conditions.

The cartridge is jammed
If the cartridge is jammed or the backup application is unable to eject it, you can force eject the
cartridge. Once the car tridge is successfully ejected, it is good practice to run Library & Tape Tools to
diagnose the problem and to upgrade the rmware. If the failure occurs regularly, contact customer
service at h
ttp://www.hp.com/support.
1. Either press and hold the Eject button on the front of the tape drive for at least 10 seconds.
2. Waitforthecartridgetobeejected. Thisprocessmaytakeupto10minutes(themaximumrewind
time). It is important that you allow sufcient time for the drive to complete this process. If you
interrupt it, you may damage the media or the tape drive. The drive is then reset as though you
had turned the power off and then on again.
You may lose data if you force eject a cartridge. The tape may also become unreadable because an
EOD (End of Data) mark may not be properly written.
3. If the cartridge is still jammed, the tape drive has failed. Contact customer service at
h
ttp://www.hp.com/support.
Emergency reset
As a last resort, if the drive has disappeared from the system a n d appears to have failed, it c an be reset
by pressing the emergency reset button, Figure 1 on page 13. (Use the tip of a paperclip to press the
but
ton.) This will allow the drive to reset its internal hardware, including the SAS port, and potentially
make it visible to a host again.
The reset process may take up to 10 minutes (the maximum rewind time) to complete.
