Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

If you use the Veritas Cluster Server product, all disk group failover issues can be
managed correctly. VCS includes a high availability monitor and includes failover
scripts for VxVM, VxFS, and for several popular databases.
The -t option to vxdg prevents automatic re-imports on reboot and is necessary
when used with a host monitor (such as VCS) that controls imports itself, rather
than relying on automatic imports by Veritas Volume Manager.
See the Veritas Volume Manager Troubleshooting Guide.
Administering VxVM in cluster environments
The following sections describe the administration of VxVM’s cluster functionality.
Note: Most VxVM commands require superuser or equivalent privileges.
Requesting node status and discovering the master node
The vxdctl utility controls the operation of the vxconfigd volume configuration
daemon. The -c option can be used to request cluster information and to find out
which node is the master. To determine whether the vxconfigd daemon is enabled
and/or running, use the following command:
vxdctl -c mode
Table 13-6 shows the various messages that may be output according to the current
status of the cluster node.
