Figure 11-20 A3542A Front Panel; Firmware Upgrade Tape Procedure: - HP 9000 Series Service Manual

Firmware Upgrade Tape Procedure:

• Shut down the operating system.
NOTE
There can be no activity on the SCSI bus and no interruption of power during this
procedure. Either event can cause the device to become unusable (DEAD DRIVE) and
will require the device to be replaced.
• Clean the drive with the cleaning cartridge.
• Insert the firmware update tape. The drive will now take over the activity and accomplish the
update.
• WAIT UNTIL ALL ACTIVITY HAS FINISHED before removing the update tape from the drive.
This is approximately two to three minutes.
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
