Solaris Enterprise Volume Manager

Hi,
I have about two volumes with plexes built out of subdisks from rood disk under rootdg and subdisks from datadg. There are no mount points associated with those volumes. Out of the two volumes one is a swapvol (name of volume ) and other is rootvol (name of the volume). My question is how do I make use of those two volumes with out crashing them.
