Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

■ To obtain I/O fencing cluster information on the CP server, run the following
command on one of the cluster nodes:
# cpsadm -s cp_server -a list_membership -c cluster_name
where cp server is the virtual IP address or virtual hostname on which the CP
server is listening, and cluster name is the VCS name for the SF Oracle RAC
cluster.
Nodes which are not in GAB membership, but registered with CP server indicate
a pre-existing network partition.
Note that when running this command on the SF Oracle RAC cluster nodes,
you need to first export the CPS_USERNAME and CPS_DOMAINTYPE variables.
The CPS_USERNAME value is the user name which is added for this node on
the CP server.
■ To obtain the user name, run the following command on the CP server:
# cpsadm -s cp_server -a list_users
where cp server is the virtual IP address or virtual hostname on which the CP
server is listening.
The CPS_DOMAINTYPE value is vx.
The following are export variable command examples:
# export CPS_USERNAME=_HA_VCS_test-system@[e-mail]
# export CPS_DOMAINTYPE=vx
Once a pre-existing network partition is detected using the above commands, all
spurious keys on the coordinator disks or CP server must be removed by the
administrator.
