VERITAS Volume Manager 3.5 Administrator's Guide (September 2002)

Chapter 2, Administering Disks

Removing Disks

3. If there are any volumes on the disk, VxVM asks you whether they should be

evacuated from the disk. If you wish to keep the volumes, answer y. Otherwise,

answer n.

4. At the following veriﬁcation prompt, press Return to continue:

Requested operation is to remove disk disk01 from group rootdg.

Continue with operation? [y,n,q,?] (default: y)

The vxdiskadm utility removes the disk from the disk group and displays the

following success message:

Removal of disk disk01 is complete.

You can now remove the disk or leave it on your system as a replacement.

5. At the following prompt, indicate whether you want to remove other disks (y) or

return to the vxdiskadm main menu (n):

Remove another disk? [y,n,q,?] (default: n)

Removing a Disk with Subdisks

You can remove a disk on which some subdisks are deﬁned. For example, you can

consolidate all the volumes onto one disk. If you use the vxdiskadm program to remove

a disk, you can choose to move volumes off that disk. To do this, run the vxdiskadm

program and select item 2 (Remove a disk) from the main menu.

If the disk is used by some subdisks, the following message is displayed:

The following volumes currently use part of disk disk02:

home usrvol

Subdisks must be moved from disk02 before it can be removed.

Move subdisks to other disks? [y,n,q,?] (default: n)

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

not movable. A subdisk may not be movable for one of the following reasons:

◆ There is not enough space on the remaining disks in the subdisk’s disk group.

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

or striped subdisks in the volume.

If the vxdiskadm program cannot move some subdisks, remove some plexes from some

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

“Removing a Volume” on page 205 and “Taking Plexes Ofﬂine” on page 154 for

information on how to remove volumes and plexes.
