Recovering Firmware Image

CMC enters recover mode when a normal CMC operating boot is not possible. In recover mode, a small subset of commands are available that allow you to reprogram the flash devices by uploading the firmware update file, firmimg.cmc. This is the same firmware image file used for normal firmware updates. The recovery process displays its current activity and boots to the CMC OS upon completion.

When you type recover and then press <Enter> at the recovery prompt, the recover reason and available sub-commands display. An example recover sequence may be:
recover getniccfg
recover setniccfg 192.168.0.120 255.255.255.0
192.168.0.1
recover ping 192.168.0.100
recover fwupdate -g -a 192.168.0.100
NOTE Connect the network cable to the left most RJ45.
NOTE In recover mode, you cannot ping CMC normally because there is no active network stack. The recover ping <TFTP server IP> command allows you to ping to the TFTP server to verify the LAN connection. You may need to use the recover reset command after setniccfg on some systems.
