NAME

vgextend - Extend a volume group by adding physical volumes to it  

SYNOPSIS

/usr/sbin/vgextend [-x Extensibility] [-v VGDA] VolumeGroupName PhysicalVolumePath ...  

DESCRIPTION

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

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: Allows the allocation of additional physical extents on the physical volume. (The default.) Prohibits the allocation of additional physical extents on the physical volume. The logical volumes that reside on the physical volume can still be accessed. 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: Allows the creation of a VGDA on the physical volume. (The default.) 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.
