Adding a Disk to the Volume Manager

New disks must be set up on the system, placed under Volume Manager control, and added to a disk group before they can be used for volumes. The add disk(s) task performs these tasks to prepare new disks for Volume Manager use. You can also use this task to add a disk to a disk group.

When you place a disk under Volume Manager control, the disk is initialized. Initialization destroys any existing data on the disk.

This task assigns a default Volume Manager disk name to the disk. Once the disk is under Volume Manager control, you can use the Rename Disk task to change the Volume Manager disk name (see “Renaming a Disk”).

To add a disk to the Volume Manager

If the disk is brand new, select the appropriate host machine node and choose Hosts > Scan Disks (Selected menu) to set up the disk on the system. This runs the disk setup commands appropriate for the operating system.
Select the uninitialized disk to be placed under Volume Manager control.
Choose Disks > Add (Selected menu) or Disk Add (Command Launcher).

Complete the Add Disk(s) dialog box as follows:

Disk Device(s):

If the correct disk (device) name is not already displayed in this field, type the disk's device name or click Browse to select the disk.

To set up any new disks on the system, click Scan Disks. This runs the disk setup commands appropriate for the operating system.

Add Disk(s) to:

To add the disk(s) to an existing disk group, select Existing Disk Group. Type the disk group name in the Disk Group Name field or click Browse to select a disk group.
To add the disk(s) to a new disk group, select New Disk Group. Type the name of the new disk group in the Disk Group Name field. The new disk group will be created for the new disk.
To place the disk(s) in the free disk pool, select Free Disk Pool. Disks in the free disk pool are under Volume Manager control, but do not belong to a disk group and cannot be used to create volumes.

Notes:

This task requires a disk device name and the location for the new disk (that is, a disk group or the free space pool).
This task sets up disks for Volume Manager use. Disks must be under Volume Manager control and in a disk group before they can be used to create volumes.
Disks in the free disk pool need to be added to a disk group before they can be used to create volumes.
Disks must be online before they can be added to a disk group or the free disk pool.
Disks that already belong to a disk group cannot be added to another disk group or placed in the free disk pool.
Disks cannot be added to deported disk groups.
The Volume Manager disk name must be unique within the disk group.
If multiple disks are specified in the Disk Device(s) field and only one disk name is specified in Disk Name(s) field, the Volume Manager appends numbers to the disk name so that each disk name is unique within its disk group.
