Reconfiguration tasks
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 160 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 92 for more information.
