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.
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
Run the vxdiskadm program and select 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)
