In a MetroCluster configuration, the ha-config state of the controller module and chassis components must be set to mcc so they boot up properly.
The system must be in Maintenance mode.
This task must be performed on each new controller module.
In Maintenance mode, display the HA state of the controller module and chassis:
The HA state for all components should be "mcc".
If the displayed system state of the controller is not correct, set the HA state for the controller module:
ha-config modify controller mcc
If the displayed system state of the chassis is not correct, set the HA state for the chassis:
ha-config modify chassis mcc
Repeat these steps on the other replacement node.
