  mount [-t vxfs] -o ro,snapof=source,[snapsize=size] \
  destination snap_mount_point

source	The mount point of the file system to copy.
destination	The name of the special device on which to create the snapshot.
size	The size of the snapshot file system in sectors.
snap_mount_point	Location where to mount the snapshot; snap_mount_pointmust exist before you enter this command.
