56 DLT VS80 Tape Drive Reference Guide
The host server does
not recognize your DLT
VS80 tape drive.
(continued)
The SCSI bus might be
too long.
Make sure the total length of
the SCSI bus does not exceed
the ANSI SCSI standard of 40
feet (12.2 meters) for an LVD
SCSI bus with multiple devices,
82 feet (25 meters) for an LVD
SCSI bus with a single device,
or 10 feet (3.05 meters) for a
Fast SCSI-2 or Ultra SCSI-1SE
bus.
There are fatal or
non-fatal errors for
which you cannot find
the cause.
The SCSI bus might be
improperly terminated.
1. If the DLT VS80 tape drive
is the last or only device
on the SCSI bus, make
sure the drive is properly
terminated. Make sure
only the last device is
terminated.
2. If the DLT VS80 tape drive
is not the last or only
device on the SCSI bus,
check all SCSI cable
connections and make
sure the last device on the
SCSI bus is terminated.
The AC power source
may not be properly
grounded (external
drive only).
1. Plug the tape drive power
cable into a power outlet
on the same circuit as the
host server.
2. Plug the DLT VS80
external tape drive power
cable into a different
power outlet.
