Solution
The SCSI bus might
be too long.
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 a Low-Voltage
Differential (LVD) SCSI bus with multiple
devices, or 82 feet (25 meters) for an LVD
SCSI bus with a single device. If you attach
the drive to an SE bus or if there are any SE
devices attached to the bus, the bus is
limited to the maximum cable lengths of an
SE bus.
The SCSI bus might
be improperly
terminated.
1. If your DLT VS160 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 your DLT VS160 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.
3. Make sure termination is set properly on
the SCSI host adapter.
4. If you attach the drive to a narrow (50-
pin) SCSI bus, you must use a
customer-supplied 68-pin to 50-pin
adapter that terminates the unused 18
pins. These adapters are sometimes
labeled "high-byte termination."
5. Regardless of which device is used to
terminate the SCSI bus, it must have
power applied and be turned on for
proper termination to occur.
There are fatal or
nonfatal errors for
which you cannot find
the cause.
The AC power source
may not be properly
grounded (DLT VS160
External Drive only).
1. Plug your DLT VS160 External Drive's
power cable into a power outlet on the
same circuit as the host server.
2. Plug your DLT VS160 External Drive’s
power cable into a different power
outlet.
The backup
application does not
recognize the drive.
Application not
compatible or
improper device
drivers installed.
If the operating system recognizes the
drive, but not the backup application,
confirm that you are using a compatible
backup application. Also confirm that you
have the proper device drivers, if
necessary, installed. See the Tandberg
support website at www.tandberg.com to
obtain the latest operating system drivers
and/or firmware upgrades.
