– An image corruption. In this case, upload the CMC rmware image to recover the CMC.
NOTE: A normal CMC boot or reset takes over a minute to fully boot into its operating system and be available for login. The
blue LED is enabled on the active CMC. In a redundant, two-CMC conguration, only the upper-right green LED is enabled on
the standby CMC.
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.
• Conguration changes to the network interfaces.
The trace log may also contain CMC rmware-specic error codes that are related to the integrated CMC rmware, 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 Conguration — Deletes the virtual disks and hot spares. However, the data on the disks is not erased.
NOTE
: Resetting PERC conguration 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 Conguration, 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.
• Disable Fault Tolerance — Disables the fault-tolerance mode of the External shared PERC 8 card.
NOTE
: Enable Fault Tolerance and Disable Fault Tolerance are displayed only for the External Shared PERC 8 cards. The
default mode of the External Shared PERC 8 cards is the non-fault-tolerant mode.

• The command fails if the blade is powered ON.
