4.
Run the HP Library and Tape Tools (L&TT) Stuck Tape test.
Run L&TT
on a host connected to the product, select the
drive, select the tests and run the Stuck Tape test.
•
This test can overcome many non-physical causes of a stuck tape.
•
Follow the instructions in L&TT. It may take several minutes and may not appear to be
doing anything. Allow the test to complete on its own.
•
Check the results when the test is complete for additional information and suggestions.
NOTE:
While L&TT is running it is good practice to obtain a Support Ticket to capture all
the logs in case they are needed by HP Support.
5.
If the cartridge could be ejected prior to this step, there is no problem with the drive or media
and the following steps are not required. If it could not be ejected using the steps above, there
may be a problem with the cartridge or drive.
Power down the drive.
6.
Disconnect the data cable.
7.
After at least 15 seconds, power the drive back up and wait till the drive is idle/ready.
CAUTION:
Use care when disconnecting data cables to ensure that connectors are not
reversed, pins are not bent, and so on.
IMPORTANT:
Powering up with a cartridge in the drive can take several minutes. It is
important that you allow sufficient time for the drive to complete rewinding the cartridge. If
you interrupt it, you may damage the media or the tape drive.
8.
Ensure that drive activity has stopped (waiting 10 minutes after power up is a good rule of
thumb). Push the Eject button.
This step attempts to overcome unload issues due to the drive being in an abnormal state or
because Prevent Media Removal has been incorrectly left on after being set by a rogue
application.
9.
Initiate a force eject or emergency unload operation by pressing and holding the Eject button
for 15 seconds. This step causes the drive to try everything possible to unload the tape.
CAUTION:
You may lose data if you force eject a cartridge that is in the middle of a backup.
The tape may also become unreadable because an EOD (End of Data) mark may not be
properly written.
10. If the cartridge is still jammed, the tape drive has failed. Contact customer support at
.
Once the cartridge is successfully ejected, it is good practice to run Library & Tape Tools to diagnose
the problem and upgrade the firmware. If the failure occurs regularly on multiple cartridges, contact
customer support at
Emergency reset
As a last resort, if the drive has disappeared from the system and appears to have failed, it can
be reset by pressing the emergency reset button,
Front view of LTO Ultrium tape drive (page 6)
(Use the tip of a paperclip to press the button.) 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.
