Terminator. Check the terminator used on the tape drive.
Both LTO-2 and LTO-3 SCSI tape drives are Ultra 160 SCSI devices and require
a minimum Ultra 160 non-RAID SCSI card, Ultra 160 rated SCSI cabling, and
an Ultra 3 Active SCSI terminator. Cabling and termination rated higher (Ultra
320, for example) is also acceptable.
An appropriate terminator is stamped with Ultra 3 or LVD 160 and “Active
Negation.”
Your library was shipped with the appropriate terminator. If you incorporate
the library into an existing setup that is not properly terminated, or if the
original terminator is replaced during setup, you may experience the failures
described below.
Failure symptoms include:
Read/Write failure
Bus hangs
Connectivity issues—tape drive not seen on bus or drops off bus
Command failures—commands to this device may fail while commands to
other devices on the bus may work properly

Your backup software may report an error as a result of a failure to
communicate with the tape drive(s) or library, a failure by a tape drive to write
or read data, or because of a software configuration issue.

Communication problems on the SCSI bus may be reported by the backup
application as resets, a loss of communication with a tape drive, failure to
detect a tape drive, I/O device errors, or parity errors. These types of errors
may occur intermittently.
If you have a SCSI library, check the tape drive’s installation on the SCSI bus,
If you have a Fibre Channel connection to your library (the tape drives
installed in the library are Fibre Channel), check the Fibre Channel
connection, described in
.

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