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.
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 subdisks 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.
To remove a disk with subdisks
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)
