520 Configuring Veritas Volume Manager
Reconfiguration tasks
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 Storage Foundation
Cluster File System environment, see the Veritas Storage Foundation Cluster File
System Installation 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 168 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 91 for more information.
