Joining Subdisks
Joining subdisks combines two or more existing subdisks into one
subdisk. To join subdisks, the subdisks must be contiguous on the same
disk. If the selected subdisks are associated, they must be associated
with the same plex, and be contiguous in that plex. To join a subdisk, use
the following command:
# vxsd join subdisk1 subdisk2 new_subdisk
