Upgrade Firmware
The upgrade firmware (WRITE_BUFFER)) command is used to transfer
firmware to the Interface Manager over Fibre Channel. Multiple upgrade
firmware commands will be required to accomplish the total transfer. All write
commands except the final write, will have the 3-bit mode field set to 0x06.
The last write command in the sequence will have the mode field bits set to
0x07 to signify the end of transfer. Each WRITE_BUFFER command will return
an FCP response.
Upgrading the firmware is successful when the FCP response returns 0x00
(success). When the transfer process is complete and the firmware image has
been successfully written to FLASH, the Interface Manager will respond to the
last transfer with 0x00, then re-boot with the upgraded firmware. If any errors
occur, the controller will return an FCP_RSP response RC value other than
0x00 and the Interface Manager will abort the upgrade. In this case, the
Interface Manager will not re-boot and the previous version of firmware will
remain intact. The host will issue a WRITE_BUFFER command as described in
Table 4 on page 118.
