The Firmware Update page displays the current version of the rmware for each listed component and allows you to update the

rmware to the latest version.

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 IP information for iDRAC and CMC, and the CMC service- or asset tag using RACADM, run the racadm getsysinfo

sub-command. For more information about other RACADM commands, see the Chassis Management Controller for PowerEdge

VRTX RACADM Command Line Reference Guide.

Updating the CMC Firmware

You can update the 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 the Chassis Conguration Administrator privilege.

If a Web user interface session is used to update system component rmware, the Idle Timeout (0, 60–10800) setting must be set

to a higher value to accommodate the le transfer time. In some cases, the rmware le transfer time may be as high as 30 minutes.

To set the idle timeout value, see Conguring Services.

During CMC rmware updates, it is normal for some or all of the fan units in the chassis to rotate at 100% speed.

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:

• The CMC rmware cannot be updated to any earlier version other than 2.0 for a chassis that is congured with 1600W

PSU.

• CMC rmware update or roll back is supported only for rmware versions 1.2, 1.25, 1.3, 1.31, 1.35, 1.36, 2.0, 2.01 and 2.04

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

the CMC with the earlier rmware becomes the standby. For information about swapping roles, see the cmcchangeover

command section in the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide. Running

this command helps 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 rmware revision 2.x updates both the primary CMC and the redundant CMC without running

the

cmcchangeover command.

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.

To avoid disconnecting other users during a reset, notify authorized users who may log in to CMC and check for active sessions on

the Sessions page. To open the Sessions page, click Chassis Overview in the left pane, click Network, and then click the Sessions.
