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.
