cartridge. If attempting to read, no action is required. Because this cartridge
cannot be written, if you attempt a write operation, your backup application
should return a "Write Protected" message.
The drive cannot read the calibration tracks on the tape or has encountered
a permanent write or read error. If the failure is the result of a calibration
error, the drive ejects the cartridge. If the failure is the result of a permanent
read/write error, the drive does not eject the cartridge. Try a known-good
cartridge. If condition persists with a particular cartridge, discard or degauss
that cartridge. If repeatable with a known-good cartridge, try cleaning the
drive. If cleaning does not help, replace the drive or contact Technical
Support.
Drive continues to function, although increased soft error rates may be
encountered. Clean the drive at your earliest convenience. LED indication
remains until drive is cleaned.
Eject tape, power cycle or reset drive. Try diagnostic again with a different,
known-good tape.
NOTICE: This feature overwrites any data currently on the cartridge.
Confirm that the selected cartridge does not contain important data.
If this condition persists with a known-good cartridge, contact Technical
Support.
Power cycle or reset the drive. Try the operation again with a known-good
cartridge. If condition persists, contact Technical Support.

Solution
Regardless of the number of SCSI devices attached to the server that
is to be the host for the PowerVault 110T DLT VS160 Tape Internal
drive, each must have a unique SCSI ID. Check the SCSI IDs on all
other SCSI devices on the selected server, including the SCSI host
adapter, and select an unused SCSI ID for the PowerVault 110T DLT
VS160 Tape Internal drive.
NOTE: If you attach the drive to a narrow (50-pin) bus, you can
only use SCSI IDs 0 through 7.
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 external and internal
drives.
1. Make sure an active Low-Voltage Differential/Single-Ended
(LVD/SE) terminator is properly seated on the open SCSI
connector on the rear panel of the external drive or on the last
device on the SCSI bus.
