In a multi-node cluster the cluster nodes are unable to see any other cluster node.state:unknown
For example,in a 2-node cluster.

Solution:
Check engine_A.log and look for cluster start with "onenode" option:
2010/01/0215:55:18 VCS NOTICE V-16-1-11022 VCS engine (had) started
2010/01/0215:55:18 VCS NOTICE V-16-1-11027 VCS engine startup arguments=-onenode<<<<<<
2010/01/0412:34:25 VCS NOTICE V-16-1-11022 VCS engine (had) started
To resolve this run:
#hastop -all-force
#hastart<<<<< on every node
LINUX :
- In linux a node start as onenode cluster ( configured in multinode cluster ) after reboot.
- this is because of argument ONENODE=yes defined in /etc/sysconfig/vcs file.
Please edit /etc/sysconfig/vcs file and change ONENODE=yes to ONENODE=no
The node will start without ONENODE argument will join other nodes to form cluster.
