See the Veritas Volume Manager Troubleshooting Guide for more information on Veritas
Volume Manager error messages.
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.
