Raghava,

Are your servers going directly into a Fibre Channel
Switch or into a router.  Which
fc hba's are in your server???   When you do nsrjb are
you seeing the
drives???  Are you seeing errors /var/adm/messages
indicating that the
drives are missing or have disappeared??   If going
directly into a Fibre Channel
switch ask your SAN admin if they see the drives in
the Name Server.
