veritad 2.x dose not support DMP we had a fe problems and VERITAS
SUPPORT ASKED US TO UPGRADE IT TO VERITAX 3.X ...
BETTER UPGRADE IT TO VERITAS 3.X ...
vxxm 3.x by default if it sees two paths to a disk it automatically
vxdisk list < veritas disk name >
will show you the multi[hating information ..
my advise : upgrade your vxvm ... to 3.x .. else you will have
problems with 2.x ..
