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
). Alternatively, if your autoloader is equipped with the optional
Ethernet port, you can use FTP to obtain a diagnostic log from the
autoloader (see

✔
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.
