•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 <01>

•To enable IP blocking feature, use:

racadm config –g cfgRacTuning –o cfgRacTuneIPBlkEnable <01>

•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

For more information about these objects, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide available at dell.com/support/manuals.

Understanding Redundant CMC Environment

You can install a standby CMC that takes over if your active CMC stops functioning. The redundant CMC may be pre-installed or can be installed later. To make sure full redundancy or best performance, it is important that the CMC network is properly cabled.

Failovers can occur when you:

•Run the RACADM cmcchangeover command. See the cmcchangeover command section in the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide available at dell.com/support/manuals.

•Run the RACADM racreset command on the active CMC. See the racreset command section in the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide available at dell.com/support/manuals..

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