TAPE DRIVE TROUBLESHOOTING
If you are unable to resolve the problem, use LibTool to obtain a diagnostic
log from the autoloader immediately after the error is reported (see
page 102). Alternatively, if your autoloader is equipped with the optional
Ethernet port, you can use FTP to obtain a diagnostic log from the
autoloader (see page 100). Exabyte Technical Support can examine the log
to determine the nature of the reported error.
✔ Firmware level. Make sure that your autoloader and tape drive contain the
latest versions of firmware.
To check the autoloader’s code level, see page 79.
To check the tape drive’s code level, see page 85.
To determine whether you have the latest version of firmware, check the
Exabyte web site at www.exabyte.com/downloads.
TAPE DRIVE TROUBLESHOOTING
TAPE DRIVE OPERATION
Refer to the tape drive product manual for detailed tape drive troubleshooting
information. If you have been successfully operating the application software
and autoloader in the past, but are now experiencing problems reading and
writing data, check the following:
✔ Write-protect switch. If you are writing data, make sure that the cartridge is
write-enabled (see page 63).
✔ Cartridge type. Use the appropriate cartridges for your tape drive. See
page 63 for information about selecting cartridges.
✔ Cartridge age. If the cartridge has been in use for a long time or if it has been
used frequently, try using a new cartridge.
✔ Cleaning. Clean the tape drive as described on page 70.
TAPE DRIVE FAILS WITH SPORADIC ERRORS.
✔ Terminator. Check the terminator used on the tape drive.
Both LTO-2 and LTO-3 tape drives are Ultra 160 SCSI devices and require a
minimum Ultra 160 non-RAID SCSI card, Ultra 160 rated cabling, and an
Ultra 160 Active terminator. Cabling and termination rated higher (Ultra
320, for example) is also acceptable.

! Important
Both LTO-2 and LTO-3 tape drives require an Ultra 3 or
LVD 160 terminator to function properly on the SCSI bus. An
inadequate terminator will result in various, sporadic SCSI bus
issues, including bus hangs and Read/Write failures.
