SCSI ID

ID

Solution
• Make sure the cartridge is write enabled. (Move the write-
protect switch to the enabled position.)
• Make sure the cartridge is HP LTO compatible.
• 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 from, 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
for instructions.
• Make sure all SCSI devices on the same bus have a unique ID
number.
• If the SCSI bus is narrow (50-pin), verify that only SCSI IDs 0
through 7 are being used.
• Make sure to cycle power on the ValueLoader after changing
the SCSI ID.
• Reboot the host server.
