To break an established connection between a subdisk and the plex to which it belongs, the subdisk is dissociated from the plex. A subdisk is dissociated when the subdisk is removed or used in another plex. To dissociate a subdisk, use the following command:
# vxsd [-g diskgroup] [-o force] dis subdisk
For example, to dissociate a subdisk named mydg02-01 from the plex with which it is currently associated in the disk group, mydg, use the following command:
# vxsd -g mydg dis mydg02-01
You can additionally remove the dissociated subdisks from VxVM control using the following form of the command:
# vxsd [-g diskgroup] -o rm dis subdisk
