VIP showing INTERMEDIATE and FAILED OVER

We received complain from application team, that we are not able to do connect database. But when we checked, database is up and running fine. One database configured in one of the 2-Node RAC (11gR2 RAC cluster). From verification found VIP of that node is in "INTERMEDIATE and FAILED OVER" state. Listeners are running fine in both nodes.

So, the issue is, VIP was showing as INTERMEDIATE and FAILED OVER in one of RAC node 

Checked crs the status and here is the sample output:

$ crsctl status resource -t

......
ora.example1a.vip
      1        ONLINE  ONLINE       example1a                              
ora.example1b.vip
      1        ONLINE  INTERMEDIATE example1a          FAILED OVER         
$ 

-- Now Check that particular VIP status

[oracle@example1b ~]$ crsctl status resource ora.example1b.vip
NAME=ora.example1b.vip
TYPE=ora.cluster_vip_net1.type
TARGET=ONLINE
STATE=INTERMEDIATE on example1a
