48 ValueLoader DLT VS80/DLT VS160 Tape Autoloader User Manual

Cannot write to or read

from a tape

• Make sure the cartridge is write enabled (move the write-

protect switch to the enabled position).

• Make sure that the cartridge is a DLTtape that has not been

written using an incompatible format. The ValueLoader VS80

drive can read, but not write, a DLT4000 formatted tape. The

ValueLoader VS160 drive can read, but not write, DLTtape IV

media.

• Make sure the cartridge has not been exposed to harsh

environmental or electrical conditions and is not physically

damaged in any way.

• Many backup applications do not read or write to cartridges

that were created using a different backup application. In this

case, you may have to perform an erase, format, or label

operation on the cartridge.

• Make sure you understand any data protection or overwrite

protection schemes that your backup application may be

using, which could prevent you from writing to a given

cartridge.

• Retry the operation with a different, known good tape.

• Clean the tape drive. See Cleaning the Tape Drive

on page 30

for instructions.

SCSI ID

Changed drive SCSI ID,

but the host server does

not recognize the new ID

• Make sure all SCSI devices on the same bus have unique ID

numbers.

• If the SCSI bus is narrow (50-pin), only SCSI IDs 0 through 7

are available.

• Make sure that you cycle power on the ValueLoader after

changing the SCSI ID.

• Reboot the host server.
