Viewing Currently Installed Firmware Versions

You can view the currently installed firmware versions using the CMC web interface or RACADM.

Viewing Currently Installed Firmware Versions Using CMC

Web Interface

In the CMC web interface, go to any of the following pages to view the current firmware versions:

• Chassis Overview > Update

• Chassis Overview > Chassis Controller > Update

• Chassis Overview > Server Overview > Server Component Update

• Chassis Overview > I/O Module Overview > Update

• Chassis Overview > Storage > Storage Component Update

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

firmware 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

firmware, 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 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 the Chassis Configuration Administrator privilege.

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

higher value to accommodate the file transfer time. Sometimes, the firmware file transfer time may be as high as 30 minutes. To set the

idle timeout value, see Configuring Services.

During CMC firmware 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 firmware version, at the

same time, with a single operation. If CMCs have different firmware and a failover occurs, unexpected results may occur.

NOTE:

• The CMC firmware cannot be updated to any earlier version other than 2.0 for a chassis that is configured with

1600W PSU.

• CMC firmware update or roll back is supported only for firmware 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, 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 the

CMC with the earlier firmware 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 firmware is working properly, before you update the firmware in the second
