Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

The compvol_access attribute can be specified to the vxvset set command to
change the access mode to the component volumes of a volume set. If any of the
component volumes are open, the -f (force) option must be specified to set the
attribute to read-only.
The following example sets the makedev=on and compvol_access=read-only
attributes on a volume set, myvset2, in the disk group, mydg:
# vxvset -g mydg set makedev=on myvset2
The next example sets the compvol_access=read-write attribute on the volume
set, myvset2:
# vxvset -g mydg set compvol_access=read-write myvset2
The final example removes raw device node access for the volume set, myvset2:
# vxvset -g mydg set makedev=off myvset2
