SCSI ID Problems

Each SCSI device on the same SCSI bus must have a unique SCSI ID.
CP 3100 units that do not contain an integrated tape drive inherit the SCSI ID of the tape
•
drive to which they are attached. If another device on the SCSI bus uses this SCSI ID, change
the SCSI ID on the tape drive or on the other device.
NOTE: Do not set the archive tape drive to SCSI ID 7. For best performance, it is strongly recom-
mended that the CP 3100 be attached to a dedicated SCSI Ultra 160 controller with no other
SCSI devices on the same SCSI cable.
CP 3100 units that contain an integrated tape drive default to SCSI ID 6. If another device on
•
the SCSI bus uses this SCSI ID, change the SCSI ID on the other device to one that is not being
used by any other device on the SCSI bus. If this is not possible, use the SCSI ID selector
switch on the back panel of the CP 3100 to select a unique SCSI ID for the unit.
NOTE: Do not set the CP 3100 selector switch to SCSI ID 7. For best performance, it is strongly
recommended that the CP 3100 be attached to a dedicated SCSI Ultra 160 controller.

SCSI Termination Problems

If the CP 3100 is the last device or the only device in a SCSI chain, install a SCSI terminator
•
on the SCSI OUT connector on the back panel of the CP 3100 (see Chapter 3, "Installing the
CP 3100" on page 23 for more information). If the CP 3100 is not the last device in the SCSI
chain, install the SCSI terminator on the last device in the chain (the manual that came with the
device should describe this procedure).
NOTE: For best performance, it is strongly recommended that the CP 3100 be attached to a
dedicated SCSI Ultra 160 controller with no other SCSI devices on the same SCSI cable.
Action Required
The CP 3100 is requesting a blank physical tape cartridge, warning that a
physical tape cartridge may be overwritten, or requesting a specific physi-
cal tape cartridge.
The immediately prior archive operation failed due to an error with the
physical tape drive or physical tape cartridge, or a physical tape cartridge
end-of-media event occurred.
You need to insert a cleaning cartridge into the physical tape drive.
The disk cache is nearly exhausted or full and you need to archive, erase,
or delete virtual tape cartridges.
