cannot be written, if you attempt a write operation, your backup application
should return a "Write Protected" message.

write/read error.

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.

Solution

The host server
does not
recognize the
drive.

The drive's SCSI ID might not be
unique.

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.

The SCSI host adapter might be
incorrectly configured.

Check the SCSI host adapter configuration. Refer to the SCSI host
adapter manuals for instructions.

The SCSI cable might be loose.

Check both ends of the SCSI cable, both for the external and internal
drives.

The SCSI terminator might be
loose or missing.

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.
