Users Guide

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.
When transferring files to and from CMC, the file transfer icon spins during the transfer. If your icon is animated, make sure that
your browser is configured to allow animations. For instructions, see Allow Animations in Internet Explorer.
If you experience problems downloading files 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.
