Making an Available Disk a Physical Volume

To be assigned to volume groups and used by the LVM, a disk must be configured as a physical volume.

Prerequisites

• The disk name must be known to the system and the disk must be available.

  To configure a disk drive, see "Configuring a Disk Drive" .

• The disk must not be currently in use by the system or any programs.

Procedure

To change an available disk to a physical volume, enter:

chdev -l hdisk3 -a pv=yes

This causes the available disk (hdisk3) to be assigned a physical volume identifier (PVID) if it does not already have one.

Note: This command has no effect if the disk is already a physical volume.
