NOTE: CMC rmware update or roll back is supported only for the rmware 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, rst update to any of these versions, and then update to
the required version.
The Active CMC resets and becomes temporarily unavailable after the rmware 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 rmware 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 rmware becomes the standby. See the cmcchangeover command section in the Chassis Management
Controller for Dell PowerEdge M1000e RACADM Command Line Reference Guide for information about swapping roles. This allows
you to verify that the update has succeeded and that the new rmware is working properly, before you update the rmware 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.
During the nal phases of the rmware update process in CMC, the browser session and connection with CMC is lost temporarily as
the CMC is not connected to the network. CMC generates the chassis overall health as critical owing to the temporary network loss.
When CMC restarts after a few minutes, log in to it. The CMC then generates the chassis overall health as healthy and the CMC
network link is up. After CMC resets, the new rmware version is displayed on the Firmware Update page.
When transferring les to and from CMC, the le transfer icon spins during the transfer. If your icon is animated, make sure that your
browser is congured to allow animations. For instructions, see Allow Animations in Internet Explorer.
If you experience problems downloading les from CMC using Internet Explorer, enable the Do not save encrypted pages to disk
option. For instructions, see Downloading Files From CMC With Internet Explorer.
