Chapter 5 181

Moving Subdisks

Moving a subdisk copies the disk space contents of a subdisk onto one or

more other subdisks. If the subdisk being moved is associated with a

plex, then the data stored on the original subdisk is copied to the new

subdisks. The old subdisk is dissociated from the plex, and the new

subdisks are associated with the plex. The association is at the same

offset within the plex as the source subdisk. To move a subdisk, use the

following command:

# vxsd mv old_subdisk new_subdisk [new_subdisk ...]

For example, if disk03 is to be evacuated and disk22 has enough room on

two of its subdisks, use the following command:

# vxsd mv disk03-01 disk22-01 disk22-02

For the subdisk move to work correctly, the following conditions must be

met:

• The subdisks involved must be the same size.

• The subdisk being moved must be part of an active plex on an active

(ENABLED) volume.

• The new subdisk must not be associated with any other plex.

See “Conﬁguring Hot-Relocation to Use Only Spare Disks” on page 328

for information about manually relocating subdisks after hot-relocation.
