In-Band Management Following are descriptions of some of the Controller LUN commands used for In-Band Management of the bridge. Download Command The Download (WRITE_BUFFER) command is used to transfer firmware to the bridge over Fibre Channel. Multiple WRITE_BUFFER 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 bridge 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 bridge will abort the upgrade. In this case, the bridge 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 9 on page 209. 208 In-Band Management Appendix B
