Configuring CMC Properties

You can configure CMC properties such as power budgeting, network settings, users, and SNMP and e-mail alerts using
the Web interface or RACADM.

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
Command Line Reference Guide for iDRAC7 and CMC) .
• Run the RACADM racreset command on the active CMC. (See the racreset command section in the
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
• 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.
