Examples of files that compress well are plain text files, spreadsheets; those that compress poorly are either compressed
as part of their format (such as, JPEG photographic files) or stored as compressed (such as, .ZIP files or .gz/.Z files on
Unix platforms).
Problems with cartridges
If you experience any problems using LTO branded cartridges, check:
•
The cartridge case is intact and that it contains no splits, cracks or damage.
•
The cartridge has been stored at the correct temperature and humidity. This prevents condensation. See the insert included
with the tape cartridge for storage conditions.
•
The write-protect switch is fully operational. It should move from side to side with a positive click.
The cartridge is jammed
If the cartridge is jammed or the backup application is unable to eject it, you can force eject the cartridge. If the failure occurs
regularly, contact Customer Support.
1.
Either press and hold the Eject button on the front of the tape drive for at least 10 seconds.
2.
Wait for the cartridge to be ejected. This process may take up to 10 minutes (the maximum rewind time). It is important
that you allow sufficient 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 Support.
The drive will not accept the cartridge (or ejects it immediately)
The cartridge may have been damaged, for example dropped, or the drive may have a fault. If it is a cleaning cartridge, it has
probably expired and should be discarded immediately. For data cartridges:
1.
Check that the drive has power (the power cable is properly connected and the Ready LED is on).
2.
Check that you are using the correct media. Use only Ultrium media, (see Use the correct media (page 25)).
•
Ultrium 6.25 TB RW and Ultrium 6.25 TB WORM tape cartridges for use with LTO–6 tape drives.
•
Ultrium 3 TB RW and Ultrium 3 TB WORM tape cartridges for use with LTO–5 tape drives.
•
Ultrium 1.6 TB RW and Ultrium 1.6 TB WORM tape cartridges for use with LTO–4 tape drives.
•
Ultrium 800 GB RW and Ultrium 800 GB WORM tape cartridges for use with LTO–3 tape drives.
3.
Make sure that you have loaded the cartridge with the correct orientation (see Loading a cartridge (page 23)).
4.
Check for damage to your media and discard it if it is damaged.
5.
Use a new or known-good piece of media and see if it loads. If it does, the original cartridge is faulty and should be
discarded.
6.
Check if another LTO drive of the same model will accept the cartridge. If it does, the original drive may be faulty. Before
calling customer service, please check that the tape drive is responding.
Encryption troubleshooting
•
Ensure that you are using an LTO-6, LTO-5 or LTO-4 tape drive and Ultrium 6.25 TB, 3 TB or 1.6 TB media, respectively.
•
Ensure that your software supports hardware encryption. It may be necessary to update the software. Consult your
software vendor for more information.
•
Ensure that the correct key or pass phrase has been entered.
•
Ensure that your HBA supports the encryption commands. It may be necessary to update the firmware.
