Using Serviceguard Extension for RAC, 6th Edition, April 2008

The following output will be generated:
Shared disk group “cfsdg1” was disassociated from the cluster.
NOTE: “cfsmntadm delete” also deletes the disk group if there is no
dependent package. To ensure the disk group deletion is complete, use the above
command to delete the disk group package.
4. De-configure CVM
# cfscluster stop
The following output will be generated:
Stopping CVM...CVM is stopped
# cfscluster unconfig
The following output will be displayed:
CVM is now unconfigured
Creating a Storage Infrastructure with CVM
In addition to configuring the cluster, you create the appropriate logical volume
infrastructure to provide access to data from different nodes.
This is done with Logical Volume Manager (LVM), Veritas Volume Manager (VxVM),
or Veritas Cluster Volume Manager (CVM). LVM and VxVM configuration are done
before cluster configuration, and CVM configuration is done after cluster configuration
(on HP-UX releases that support Veritas CFS and CVM; see “About Veritas CFS and
CVM from Symantec” (page 25)).
This section shows how to configure storage using the Veritas Cluster Volume Manager
(CVM). The examples show how to configure RAC disk groups, but you can also create
CVM disk groups for non-RAC use. For more information, including details about
configuration of plexes (mirrors), multi-pathing, and RAID, refer to the HP-UX
documentation for the Veritas Volume Manager.
Initializing the Veritas Volume Manager
If you are about to create disk groups for the first time, you need to initialize the Volume
Manager. This is done by creating a disk group known as rootdg that contains at least
one disk. Use the following command after installing CVM on each node:
# vxinstall
This displays a menu-driven program that steps you through the CVM initialization
sequence. From the main menu, choose the “Custom” option, and specify the disk you
wish to include in rootdg.
