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.
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.
See “Removing a volume” on page 371.
See “Taking plexes offline” on page 287.
