Users Guide

If the chassis contains an earlier generation server whose iDRAC is in recovery mode or if CMC detects that iDRAC has corrupted
rmware, then the earlier generation iDRAC is also listed on the Firmware Update page.
Viewing Currently Installed Firmware Versions Using RACADM
To view the currently installed rmware 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 rmware using Web interface or RACADM. The rmware update, by default, retains the current CMC settings. During
the update process, you can reset CMC conguration settings back to the factory default settings.
NOTE: To update rmware on CMC, you must have Chassis Conguration Administrator privilege.
If a Web user interface session is used to update system component rmware, the Idle Timeout setting must be set high enough to
accommodate the le transfer time. Sometimes, the rmware le transfer time may be as high as 30 minutes. To set the Idle Timeout value,
see Conguring Services.
During updates of CMC rmware, 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 rmware version at the
same time with a single operation. If CMCs have dierent rmware and a failover occurs, unexpected results may occur.
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.
NOTE
: If you have congured the slot name length to more than 15 characters in the current version of CMC, downgrading the
CMC rmware truncates the slot name length to 15 characters.
