clustat output does not show rgmanager status

Issue

• On one of the cluster nodes, the clustat output does not show rgmanager online:

$ clustat 
Cluster Status for cluster1 @ Wed Jan 16 20:19:56 2013
Member Status: Quorate

 Member Name                             ID   Status
 ------ ----                             ---- ------
 node1                                  1 Online
 node2                                  2 Online, Local

• Also, the services are failing to start on affected node with below error:

$ clusvcadm -e service1
Local machine trying to enable service:service1...Service does not exist

• But rgmanager service is shown to be running in ps and service rgmanager status outputs:

$ grep -i rgmanager ps
root      6309  0.0  0.0  36936  6236 ?        S<Ls 10:00   0:00 rgmanager
root      6242  0.0  0.0 408640  2288 ?        S<l  10:00   0:00 rgmanager

$ service rgmanager status
rgmanager (pid  6309) is running...
