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.
