Viewing Currently Installed Firmware Versions Using RACADM
To view the currently installed firmware versions using RACADM, use the getkvminfo subcommand. For
more information, see the Chassis Management Controller for Dell PowerEdge M1000e RACADM
Command Line Reference Guide.
Updating CMC Firmware
You can update CMC firmware using Web interface or RACADM. The firmware update, by default, retains
the current CMC settings. During the update process, you can reset CMC configuration settings back to
the factory default settings.
NOTE: To update firmware on CMC, you must have Chassis Configuration Administrator privilege.
If a Web user interface session is used to update system component firmware, the Idle Timeout setting
must be set high enough to accommodate the file transfer time. In some cases, the firmware file transfer
time may be as high as 30 minutes. To set the Idle Timeout value, see Configuring Services.
During updates of CMC firmware, it is normal for some or all of the fan units in the chassis to spin at
100%.
If you have redundant CMCs installed in the chassis, it is recommended to update both the CMCs to the
same firmware version at the same time with a single operation. If CMCs have different firmware and a
failover occurs, unexpected results may occur.
NOTE: CMC firmware update or roll back is supported only for the firmware versions 3.10, 3.20,
3.21, 4.0, 4.10, 4.11, 4.30, 4.31, 4.45, 4.5, 5.0, and later. For any version other than these, first update
to any of these versions, and then update to the required version.
The Active CMC resets and becomes temporarily unavailable after the firmware has been uploaded
successfully. If a standby CMC is present, the standby and active roles swap. The standby CMC becomes
the active CMC. If an update is applied only to the active CMC, after the reset is complete, the active
CMC does not run the updated image, only the standby CMC has that image. In general, it is highly
recommended to maintain identical firmware versions for the active and standby CMCs.
When the standby CMC has been updated, swap the CMCs’ roles so that the newly updated CMC
becomes the active CMC and CMC with the older firmware becomes the standby. See the
cmcchangeover command section in the Chassis Management Controller for Dell PowerEdge M1000e
RACADM Command Line Reference Guide.
information about swapping roles. This allows you to verify that the update has succeeded and that the
new firmware is working properly, before you update the firmware in the second CMC. When both CMCs
are updated, you can use the cmcchangeover command to restore the CMCs to their previous roles.
CMC Firmware revision 2.x updates both the primary CMC and the redundant CMC without using the
cmcchangeover command.
To avoid disconnecting other users during a reset, notify authorized users who may log in to CMC and
check for active sessions in the Sessions page. To open the Sessions page, select Chassis in the tree, click
the Network tab, and then click the Sessions subtab.
