Configuring Login Lockout Policy Attributes Using
RACADM
You can use RACADM to configure the Login lockout policy attributes for the following features:
• User blocking
• IP address blocking
• Number of login attempts allowed
• Timespan for the lockout failure counts to occur
• Lockout penalty time
• To enable user blocking feature, use:
racadm config -g cfgRacTuning -o cfgRacTuneUserBlkEnable <0|1>
• To enable IP blocking feature, use:
racadm config –g cfgRacTuning –o cfgRacTuneIPBlkEnable <0|1>
• To specify the number of login attempts, use:
racadm config –g cfgRacTuning –o cfgRacTuneIpBlkFailCount
• To specify the time span within which, lockout fail count failures must occur, use:
racadm config –g cfgRacTuning –o cfgRacTuneIpBlkFailWindow
• To specify value for lockout penalty time, use:
racadm config –g cfgRacTuning –o cfgRacTuneIpBlkPenaltyTime

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.
