Swapping the Primary CMM for the Secondary CMM
If the primary CMM is having problems, or if it needs to be shut down, then the secondary CMM can be
instructed to “take over” switch operation as the primary CMM is shut down.
Note. It is important that the software for the secondary CMM has been synchronized with the primary
CMM before you initiate a secondary CMM takeover. If the CMMs are not synchronized, the takeover
could result in the switch running old or out-of-date software. Synchronizing the primary and secondary
CMMs is described in “Synchronizing the Primary and Secondary CMMs” on page 4-21.
To instruct the secondary CMM to takeover switch functions from the primary CMM, enter the following
command at the prompt:
-> takeover
The takeover command is described in detail in the OmniSwitch CLI Reference Guide.
Note. The saved boot.cfg file will be overwritten if the takeover command is executed after the copy
running-config working or write memory commands, in an OmniSwitch set up with redundant CMMs.
