XEN and NPIV

[Christoph_L]

Hi guys,
im testing Xen and NPIV with SLES11.

Now I have a question. What is the difference between
disk = [ 'phys: /dev/sdb, xvda, rw' ] and disk = [ 'npiv: SANID-WWPN-WWNN-TargetID-Lun#], "/dev/sdb" is an LUN connected through an virtual HBA who is created with the same parameter which will be usd by the disk = [ 'npiv: SANID-WWPN-WWNN-TargetID-Lun#] command.

My opinion is by this command [ 'phys: /dev/sdb, xvda, rw' ], the DomU will get the raw device. By this command disk = [ 'npiv: SANID-WWPN-WWNN-TargetID-Lun#] no vHBA will be create an the DomU will have access to the volume?!?!
