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

RACADM Command

Line Reference Guide for iDRAC7 and CMC)

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

RACADM

Command Line Reference Guide for iDRAC6 and CMC)

• 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.
