4. At the following verification prompt, press Return to continue:
VxVM NOTICE V-5-2-284 Requested operation is to remove disk mydg01
from group mydg.
Continue with operation? [y,n,q,?] (default: y)
The vxdiskadm utility removes the disk from the disk group and displays the
following success message:
VxVM INFO V-5-2-268 Removal of disk mydg01 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:
VxVM ERROR V-5-2-369 The following volumes currently use part of disk
mydg02:
home usrvol
Volumes must be moved from mydg02 before it can be removed.
Move volumes 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 250 and “Taking Plexes Offline” on page 190 for
information on how to remove volumes and plexes.
