VERITAS Volume Manager 3.5 Administrator's Guide (September 2004)

Chapter 4 140
If you choose y, then all subdisks are moved off the disk, if possible. Some
subdisks may not be movable. The most common reasons why a subdisk
may not be movable are as follows:
• There is not enough space on the remaining disks.
• Plexes or striped subdisks cannot be allocated on different disks from
existing plexes or striped subdisks in the volume.
If vxdiskadm cannot move some subdisks, you may need to remove some
plexes from some disks to free more space before proceeding with the
disk removal operation.
