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, vrtx_cmc.bin. 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.
Troubleshooting Network Problems
The integrated CMC trace log allows you to debug CMC alerts and networking. You can access the trace log using the CMC
Web interface or RACADM. See the gettracelog command section in the Chassis Management Controller for PowerEdge
VRTX RACADM Command Line Reference Guide.
The trace log tracks the following information:
DHCP Traces packets sent to and received from a DHCP server.
DDNS Traces dynamic DNS update requests and responses.
Configuration changes to the network interfaces.
The trace log may also contain CMC firmware-specific error codes that are related to the integrated CMC firmware, not the
managed systems operating system.
Troubleshooting Controller
To troubleshoot a controller:
1. In the left pane, click Chassis Overview > Storage > Controllers > Troubleshooting.
2. On the Controller Troubleshooting page, from the Actions drop-down list for the respective controller, select any one of
the following, and then click Apply.
Reset Configuration Deletes the virtual disks and hot spares. However, the data on the disks is not erased.
NOTE: Resetting PERC configuration discards the pinned cache, if any, on the PERC controller.
Export TTY Log The TTY debug log from the storage controller is exported to your local system.
Discard Pinned Cache Deletes data that is stored in RAID controller cache.
NOTE:
If there is pinned cache, the option to clear it is present. If there is no pinned cache, this option is not
displayed.
Disable RAID Controller Disables the peer controller. This option is available in the drop-down menu only for the
Shared PERC8 (Integrated 2) and external Shared PERC8s.
Enable RAID Controller Enables the peer controller. Enable Raid Controller option is available in the drop-down
menu.
NOTE:
For a disabled PERC, none of the other options Reset Configuration, Export TTY Log, Discard Pinned Cache, and Disable
RAID Controller are available in the drop-down menu.
Enable Fault Tolerance Enables the fault-tolerance mode of the External shared PERC 8 card.
