To import disk groups to be shared, use the following command:
# vxdg -s import diskgroup
This procedure marks the disks in the shared disk groups as shared and stamps them
with the ID of the cluster, enabling other nodes to recognize the shared disks.
If dirty region logs exist, ensure they are active. If not, replace them with larger ones.
To display the shared flag for all the shared disk groups, use the following command:
# vxdg list
The disk groups are now ready to be shared.
3. Bring up the other cluster nodes. Enter the vxdg list command on each node to
display the shared disk groups. This command displays the same list of shared disk
groups displayed earlier.
For information on converting disk groups in a VERITAS Cluster File System (CFS)
environment, see the VERITAS Cluster File System Installation and Configuration Guide.
Reconfiguration Tasks
The following sections describe tasks that allow you to make changes to the configuration
that you specified during installation.
Changing the Name of the Default Disk Group
If you use the VERITAS installer to install the VERITAS Volume Manager software, you
can enter the name of the default disk group. This disk group will be used by commands if
you do not specify the -g option, or the VXVM_DEFAULTDG environment variable is not
set. If required, you can use the vxdctl defaultdg command to change the default disk
group. See “Displaying and Specifying the System-Wide Default Disk Group” on page 134
for details.
Enabling or Disabling Enclosure-Based Naming
If you use the VERITAS installer to install the VERITAS Volume Manager software, you
can choose whether the displayed disk access names are based on device names or on
names that you assign to disk enclosures. If required, you can use the vxdiskadm or
vxddladm commands to change the naming convention that is used. See “Changing the
Disk-Naming Scheme” on page 72 for more information.
