4. Roll back the CMC and/or mainboard firmware.
You cannot downgrade the CMC, if external shared storage adapter is detected.
If the processes are not followed in order, system behavior becomes random and parts of the system may become unstable. The
CMC logs IOV or RAID controller messages. Only shared storage VA mappings for PERC 1 and PERC 2 are visible in the older
version of CMC. All external shared storage VA mappings do not exist in the previous version of the CMC. If an External Shared
PERC 8 card is inserted after the rollback, the CMC treats it as a non-shared adapter. It may happen that the HOST PERC
driver does not support the External Shared PERC 8 card.
Updating CMC Firmware Using Web Interface
NOTE:
● Before applying the CMC update, ensure that the chassis is powered on. If the blades are powered on, it is not
necessary to power off the blades to perform the CMC update.
● Downgrading the CMC Firmware prior to 2.1 with external shared adapters is blocked.
To update the CMC firmware using the CMC web interface:
1. In the left pane, go to any of the following pages:
● Chassis Overview > Update
● Chassis Overview > Chassis Controller > Update
2. On the Firmware Update page, in the CMC Firmware section, select the required components under the Update Targets
column for the CMC or CMCs (if standby CMC is present) you want to update, and then click Apply CMC Update.
3. In the Firmware Image field, click Browse (Internet Explorer or Firefox) or Choose File (Google Chrome) to browse
through to the file location. The default name of the CMC firmware image file is vrtx_cmc.bin.
4. Click Begin Firmware Update. The Firmware Update Progress section provides firmware update status information. A
status indicator displays on the page while the image file is uploaded. File transfer time varies based on the connection
speed. When the internal update process begins, the page automatically refreshes and the Firmware update timer is
displayed.
5. For a standby CMC, when the update is complete, the Update State field displays Done. For an active CMC, during the
final phases of the firmware update process, the browser session and connection with CMC is lost temporarily because the
active CMC is not connected to the network. You must log in after a few minutes, when the active CMC has restarted. After
CMC resets, the new firmware is displayed on the Firmware Update page.
NOTE:
After the firmware update, delete the files from the web browser cache. For instructions about clearing the
browser cache, see the web browser’s online help.
Additional instructions:
● During a file transfer, do not click the Refresh icon or navigate to another page.
● To cancel the process, select the Cancel File Transfer and Update option. This option is available only during file transfer.
● The Update State field displays the firmware update status.
NOTE: The update process may take several minutes for CMC.
Updating CMC firmware using RACADM
To update CMC firmware using RACADM, use the fwupdate subcommand. For more information about RACADM commands,
see Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide.
NOTE: Run the firmware update command through only one remote racadm session at a time.
Updating Chassis Infrastructure Firmware
The chassis infrastructure update operation updates components such as the Main Board and PCIe subsystem management
firmware.
NOTE:
To update the chassis infrastructure firmware, make sure that the chassis is turned on and the servers are turned
off.
