How is a cluster disk group created using VERITAS Volume Manager (tm)?
A cluster is a group of system nodes making use of a common
set of disks. When Volume Manager controls these shared disks, the common sets
of disks are organized into disk groups. Such shared disk groups are called
"cluster disk groups."
Note: When using volumes on a disk group on one
system, care must be taken to ensure the disk group is deported on all other
systems that are part of the cluster. Unlike dynamic groups, cluster disk groups
are not auto-imported after the system is rebooted. Cluster disk groups must be
re-imported each time the system is reset.
Creating a cluster disk group
via the graphical user interface (GUI): Illustrated below are the steps to
take to upgrade a basic disk group to a cluster disk group:
1. Launch the VERITAS Volume
2. Locate the basic disk group
on the Disk View tab.
3. Right-click the disk name.
4. Choose Update To Cluster
How to create a cluster disk group via the command
line: This example demonstrates how to upgrade a basic disk group using the
1. Open a command
vxdg adddisk <accessname>
(Replace with the appropriate
variables described below).
<accessname> is the disk name or path name of the
device, such as Disk 2 or harddisk\partition0. The disk should not
contain any volumes when it is added.
-g<diskgroupname> is the name
of the disk group.
If the -C option is used, the disk that is referenced
in <accessname> is added to the cluster disk group referenced in
adddisk Disk 2 -gClusterGroup -C.
