Connecting to the Slave CMM
If you have installed two CMMs in one blade server, one should be
assigned as the master CMM and the other as the slave CMM. You
should connect to the master CMM for management purposes.
However, you may also connect to the slave CMM to check event logs,
manage login information and change CMM settings.
At the bottom is a yellow message bar showing that you are currently
connected to the slave (redundant) CMM and telling you to connect to
the master CMM. You may refer to the master CMM IP address given to
connect to the master CMM.
