Description (partial)

Pri FI and VIP goes down 
No response to Ping
Sub IP remains Up
This happens irrespective of which FI is primary
Console remains operational
Workaround :
Change cluster lead
Reboot Sub FI (Which was Primary when issue occurs)

It has been observed that Failover occurs due to mgmt-if-mon-policy triggering the failover (presumably due to loss of network connectivity )
The first failover completes
However during the second failover (failback to previous Primary) the process gets stuck and Primary FI and VIP loose network connectivity

UCSM 4.0(4h)
