How to check MSA LUN online to the server from MSA P2000

[choudharya]

How can I check the given LUN onlnie to the server from any MSA.  The servers mentioned below (Lsgbldn002 and lsgbldn003) are cluster node. Out of 8 disks mapped from storage devices (HP P2000 G3 FC &  HPMSA2012)  we could see only 3disk available. Out of which 2 are mapped from HP P2000 G3 FC & 1 from HPMSA2012.  The remaining five disk  which are unavailable are from HPMSA2012. To be double sure that problem is not from OS level we have unmapped and mapped disks couple of times from storage side, still we are facing same issue.
