NAME
vgextend - Extend a volume group by adding physical volumes to it
SYNOPSIS
/usr/sbin/vgextend [-x Extensibility] [-v VGDA] VolumeGroupName
PhysicalVolumePath ...
DESCRIPTION
Note
This command is no longer supported on Digital UNIX systems.
Features formerly provided by the Logical Volume Manager (LVM)
are now provided by the Logical Storage Manager (LSM). Existing
LVM volumes must be migrated to LSM, using an encapsulation
process. For information about moving LVM volumes to LSM, see
the vollvmencap(8) reference page and the manual Logical Storage
Manager.
The vgextend assigns physical volumes to the VolumeGroupName. The volume
group must be active.
You extend the volume group by adding one or more physical volumes
represented by the PhysicalVolumePath parameter(s).
After the physical volumes have been successfully added to the volume
group, they can be used.
Before assigning a physical volume to a volume group, you must create the
physical volume with the pvcreate command.
If, for any reason, one of the remaining specified physical volumes cannot
be installed into the volume group, an error message is printed. However,
the installation continues to the end of the list of physical volumes.
FLAGS
-x Extensibility
Sets the allocation permission for additional physical extents on
the physical volume specified by the PhysicalVolumePath
parameter. The Extensibility parameter is represented by one of
the following:
y Allows the allocation of additional physical extents on
the physical volume. (The default.)
n Prohibits the allocation of additional physical extents
on the physical volume. The logical volumes that reside
on the physical volume can still be accessed.
-v VGDA This option allows you to specify if a VGDA (Volume Group
Descriptor Area) of the volume group must be stored on the
physical volume. VGDA is represented by one of the following:
y Allows the creation of a VGDA on the physical volume.
(The default.)
n Prohibits the creation of a VGDA on the physical
volume.
EXAMPLES
This section contains a Digital device-specific example.
To add physical volumes rz3c and rz4c to volume group vg03, enter:
vgextend /dev/vg03 /dev/rz3c /dev/rz4c
The physical volumes rz3c and rz4c now belong to volume group vg03.
