Hello Umar, which version of lvm and what distribution? There is lvmetad in newer versions of LVM and you may need to rescan PVs (pvscan --cache $PV) However using shared storage without cluster locking is nothing but asking for trouble... It is advised to either partition the storage (set zones or whatever the SAN allows) or to set global_filter/filter on both machines so each of the machines sees only appropriate LUNs it is intended to see and use.
