LTO-2, LTO-3, and LTO-4 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:
