Understanding Redundant CMC Environment

You can install a standby CMC that takes over if your active CMC fails. The redundant CMC may be pre-installed or can be installed

later. It is important that CMC network is properly cabled to ensure full redundancy or best performance.

Failovers can occur when you:

• Run the RACADM cmcchangeover command. (See the cmcchangeover command section in the Chassis Management

Controller for Dell PowerEdge M1000e RACADM Command Line Reference Guide).

• Run the RACADM racreset command on the active CMC. (See the racreset command section in the Chassis Management

Controller for Dell PowerEdge M1000e RACADM Command Line Reference Guide).

• Reset the active CMC from Web interface. (See the Reset CMC option for Power Control Operations that is described in

Executing Power Control Operations.)

• Remove the network cable from the active CMC.

• Remove the active CMC from the chassis.

• Initiate a CMC firmware flash on the active CMC.

• Have an active CMC that is no longer functional.

NOTE: In the event of a CMC failover, all iDRAC connections and all active CMC sessions are lost. Users with lost

sessions must reconnect to the new active CMC.
