we ran into a pretty difficult to find bug with FC (would happen also with iSCSI) runing proxmox 4.3
Actually this is not a proxmox bug, but in kernel Version 3.19+ a bug in the SCSI Stack was fixed which makes using 3PAR Storage impossible.
the error in dmesg looks like this:
basically 3PAR before 3.2.2 MU3 has wrong implementation of SCSI Stack. So make sure you upgrade your 3PAR Storage to at least 3.2.2 MU3 before using proxmox! Took us a few days to find the problem as it is not very good documented.
