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 internal 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 internal CMC firmware, not the managed system’s 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 hots spares. However, the data on the disks is not erased.

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 Integrated 2 PERC when it is not disabled.

Enable RAID Controller — Enables the peer controller. If the Integrated 2 PERC is already disabled, then the Enable Raid Controller option is available in the drop-down menu.
