The current secondary CMM assumes the role of primary CMM.

Performs a complete CMM reload.

N/A

OmniSwitch 6400, 6850, 6855, 9000, 9000E

• This command causes the secondary CMM to take over the functions of the primary CMM. After this 

command, the old primary CMM is the new secondary CMM.

• Before issuing the takeover command, be sure that the secondary CMM has all software (i.e., image 

and configuration files) required to continue CMM operations.

• For information on synchronizing the primary and secondary CMM software before issuing the 

takeover command, see the 

 command.

• When the CMM modules switch primary and secondary roles, the console session to the new primary 

CMM is disconnected. To continue managing the switch, be sure that you have physical connections to 
both CMMs or local access to the switch in order to move your Ethernet or serial cable from one CMM 
to the other.

• The CPM, CFM and CPU of CMM can be reset independently.

• If a takeover command is issued and the local/remote fabric module is in up state, only the CPM will 

be reset. 

• If a takeover command is issued and the local/remote fabric module is in a down state, then the 

complete CMM will be reloaded.

• This command can also be used on the secondary CMM.

• If the switch is part of a stack with three or more switches, the next switch in “idle” mode becomes the 

secondary CMM, and the original primary CMM becomes “idle.” For more information on stacks, see 
“Managing Stacks” in the Hardware Users Guide.

Note. The saved boot.cfg file will be overwritten if the takeover command is executed after the 

 command on an OmniSwitch set up with redundant CMMs. Refer to the 

 description on 

 for more information on the takeover command and redundant manage-

ment modules.
