8-88 SCSI and I/O
Firmware Upgrade Failures:
• Wrong firmware tape - The tape will be ejected within 1/2 to one minute of activity and no update will
have been done. (Match tape part number to product model number.)
• Firmware tape used up - The tape will automatically be re-formatted by the drive as a normal data tape
and will no longer react as a firmware tape (This will occur after 200 passes).
• Firmware tape write protected - The tape will be ejected and no update will be done.
• Process interrupted at crucial point - If a power interruption occurs or activity on the SCSI bus
interferes, a DEAD DRIVE will be created.
Verify the upgrade by using appropriate diagnostic or utility. (SCSIDDS Interactive command
