Verifying single-node operation

After successfully creating a single-node cluster, start VCS and verify the cluster.

 To verify single-node cluster

1. Bring up VCS manually as a single-node cluster using hastart(1M) with the -onenode option:

   # hastart -onenode

2. Verify that the had and hashadow daemons are running in single-node mode:

   # ps -ef | grep ha

   root 288 1 0 14:49:33 ? 0:00 /opt/VRTSvcs/bin/hashadow
