Si el chasis contiene un servidor de una generación anterior cuyo iDRAC se encuentra en modo de recuperación, o si el CMC detecta que

un iDRAC contiene rmware dañado, el iDRAC de la generación anterior también aparece en la página Actualización del rmware.

Visualización de versiones de rmware actualmente instaladas

mediante RACADM

Para ver las versiones de rmware instaladas actualmente mediante RACADM, utilice el subcomando getkvminfo. Para obtener más

información, consulte Chassis Management Controller for Dell PowerEdge M1000e RACADM Command Line Reference Guide (Guía de

referencia de la línea de comandos RACADM de Chassis Management Controller para Dell PowerEdge M1000e).

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. 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 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

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.

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.
