To remove a linked break-off snapshot volume from a volume, use this command:
# vxsnap [-g diskgroup] rmmir volume|volume_set mirvol=snapvol \ [mirdg=snapdiskgroup]
The mirvol and optional mirdg attributes specify the snapshot volume, snapvol, and its disk group, snapdiskgroup. For example, the following command removes a linked snapshot volume, prepsnap, from the volume, vol1:
# vxsnap -g mydg rmmir vol1 mirvol=prepsnap mirdg=mysnapdg
