We currently have two controllers which are configured as standalone / standby. When the main controller is no longer alive the standby controller is running.
AS i can see there are three configurations:
- The mobility master configuration (mm) (192.168.200.140)
- The node configuration (standalone) (192.168.200.141)
- The other node configuration (standby) (192.168.200.142)
I noticed that when i switch off the standalone, the master configuration on the standby is not identical to the standalone controller.
I checked the nodes configuration and they are perfectly the same (Except for IP / hostname). How come the mobility master configuration is not identical on both controllers?
Furthermore, i have posted the database sync below.
