54 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 34
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.
