We are currently in the process of migrating from our old storage to the VNX with VPLEX from EMC.
We have managed to successfully claim the luns from the HP XP for 2003 MSCS and 2008 MSCS.
Not so successfull with 2012 WSFC.
I am able to claim the LUN from the HP XP but as soon as you bring the server back up after creating the storage view the disk become critical on the VPLEX and RAW in windows but obviously not useable.
I have logged a call with EMC but no joy and posted on an EMC forum with someone replying.

Would simply running Clear-ClusterDiskReservation -Disk # fix this issue?
Thing is the disks are not clustered they are presented from seperate storage arrays and the WSFC is for SQL 2012 AlwaysOn.
