Deporting a Disk Group

113

If you choose y, then all subdisks are moved off the disk, if possible. Some subdisks may

not be movable. The most common reasons why a subdisk may not be movable are as

follows:

◆ There is not enough space on the remaining disks.

◆ Plexes or striped subdisks cannot be allocated on different disks from existing plexes

or striped subdisks in the volume.

If vxdiskadm cannot move some subdisks, you may need to remove some plexes from

some disks to free more space before proceeding with the disk removal operation.

Deporting a Disk Group

Deporting a disk group disables access to a disk group that is currently enabled

(imported) by the system. Deport a disk group if you intend to move the disks in a disk

group to another system. Also, deport a disk group if you want to use all of the disks

remaining in a disk group for a new purpose.

To deport a disk group, use the following procedure:

1. Stop all activity by applications to volumes that are conﬁgured in the disk group that

is to be deported. Unmount ﬁlesystems and shut down databases that are conﬁgured

on the volumes.

2. Use the following command to stop the volumes in the disk group:

# vxvol -g diskgroup stopall

3. Select menu item 8 (Remove access to (deport) a disk group) from the

vxdiskadm main menu.

4. At the following prompt, enter the name of the disk group to be deported (in this

example, newdg):

Remove access to (deport) a disk group

Menu: VolumeManager/Disk/DeportDiskGroup

Use this menu operation to remove access to a disk group that is

currently enabled (imported) by this system. Deport a disk

group if you intend to move the disks in a disk group to another

system. Also, deport a disk group if you want to use all of the

disks remaining in a disk group for some new purpose.

You will be prompted for the name of a disk group. You will also

be asked if the disks should be disabled (offlined). For

removable disk devices on some systems, it is important to
