installing viprion 2400 - problem with management IP

We are installating a viprion 2400 with 2 blade (B2250) in it.

 

The management IP was configured (floating IP) as also a cluster member IP for each module. (see hereunder --> tmsh show sys cluster command)

 

When unit was rebooted , the floating management IP was however no longer accessible . Instead we now need to connect to one of the cluster member IP's . (GUI is also indicating we're logged on from secondary slot , which is normal to me) When rebooting again , other cluster member IP comes available. But floating management IP stays unavailable .

 

I was thinking the floating IP should remain available ? Or am i doing something wrong in the config ?
