While the firmware image is being sent to the drive via SCSI, the drive
responds to ACI commands with status
BUSY
.

While the drive is actually upgrading the firmware, it will not respond to
ACI commands.

When the firmware download is complete, the drive will reset itself and
send an ENQ control character.
It is recommended that the same ACI command sequence is followed as if the
drive had been power-cycled to ensure that the drive is configured correctly
and to verify the firmware version and ACI version.
Firmware Upgrade Via ACI
Two methods exist for updating firmware via ACI:
3
Using the Send Firmware Image command. The automation controller
sends the firmware image in one data burst outside a normal packet.
3
Using the Send Firmware Segment command. The automation controller
sends the firmware image in multiple packets.
HP intends to make the Send Firmware Image command obsolete in a future
version of the ACI. Please use the Send Firmware Segment command in all
new development. See the ACI specification for further details of both
commands.
When the firmware download is complete, the drive will reset itself and send
an ENQ control character. It is recommended that the same ACI command
sequence is followed as if the drive had been power-cycled to ensure that the
drive is configured correctly and to verify the firmware version and ACI
version.
Library Firmware Upgrade Via Tape
The ACI specification allows for upgrading the automation controller
firmware via tape. This functionality is not supported in current releases of
drive firmware and will be added at a later date subject to customer needs.
Handling Irregular Cartridges
The purpose of this section is to indicate what symptoms can be seen over the
ACI if the host issues a
MOVE MEDIUM
command to the library when an
irregular cartridge (such as a cleaning cartridge, an expired cleaning
