160 Creating and administering disk groups
Displaying disk group information
Caution: In releases of VxVM prior to 4.0, a subset of commands attempted to deduce the
disk group by searching for the object name that was being operated upon by a command.
This functionality is no longer supported. Scripts that rely on deducing the disk group
from an object name may fail.
Displaying the system-wide boot disk group
To display the currently defined system-wide boot disk group, use the following
command:
# vxdg bootdg
See the vxdg(1M) manual page for more information.
Displaying and specifying the system-wide default disk group
To display the currently defined system-wide default disk group, use the following
command:
# vxdg defaultdg
If a default disk group has not been defined, nodg is displayed. Alternatively, you can use
the following command to display the default disk group:
# vxprint -Gng defaultdg 2>/dev/null
In this case, if there is no default disk group, nothing is displayed.
Use the following command to specify the name of the disk group that is aliased by
defaultdg:
# vxdctl defaultdg diskgroup
If bootdg is specified as the argument to this command, the default disk group is set to
be the same as the currently defined system-wide boot disk group.
If nodg is specified as the argument to the vxdctl defaultdg command, the default
disk group is undefined.
Note: The specified diskgroup need not currently exist on the system.
See the
vxdctl(1M) and vxdg(1M) manual pages for more information.
Displaying disk group information
To display information on existing disk groups, enter the following command:
# vxdg list
