Solution
Check the SCSI host adapter
configuration. Refer to the SCSI
host adapter manuals for
instructions.
Check both ends of the SCSI
cable, both for the desktop and
internal drives.
1. Make sure the terminator is
properly seated on the open SCSI
connector on the rear panel of the
desktop drive or on the last device
on the SCSI bus.
2. Make sure an inline LVD/SE
terminator is in place on the SCSI
ribbon cable for the internal drive.
1. If your DLT1 drive is the last or
only device on the SCSI bus, make
sure the drive is properly
terminated.
2. If your DLT1 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.
Make sure the terminators are
placed only at each end of the
SCSI bus – one at the host adapter
and one on the last device on the
bus.
Make sure the total length of the
SCSI bus does not exceed the
ANSI SCSI standard of 19 feet (6
meters) for a single-ended (SE)
bus, 40 feet (12 meters) for an LVD
SCSI bus with multiple devices, or
82 feet (25 meters) for an LVD
SCSI bus with a single device.
