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

The vxdctl -c mode command indicates whether a node is a CVM master or CVM
slave.
Verifying the state of CVM shared disk groups
You can use the following command to list the shared disk groups currently
imported in the SF Oracle RAC cluster:
# vxdg list |grep shared
orabinvol_dg enabled,shared 1052685125.1485.csha3
Verifying the activation mode
In an SF Oracle RAC cluster, the activation of shared disk group should be set to
“shared-write” on each of the cluster nodes.
To verify whether the “shared-write”activation is set:
# vxdg list dg_name |grep activation
local-activation: shared-write
If "shared-write" activation is not set, run the following command:
# vxdg -g dg_name set activation=sw
