Hi Praveen,
Yes this is problem that agent coming up during failover, the server
state then set as NTFA_NTFSV_NEW_ACTIVE. At this state, server state
will never set to NTFA_NTFSV_UP because the implementation treats
NTFA_NTFSV_NEW_ACTIVE as NTFA_NTFSV_UP, since at both of those states
NTF service should be operational. The other states will get TRY_AGAIN
except NTFA_NTFSV_UP.
Thanks,
Minh
