Server 2008 R2 1 Qlogic HBA FC hostutils 5.3 installed. Connected luns are shown twice. I remeber that this was a problem if hostutils are not installed. But even with hostutils installed the luns are shown twice. This server only has one connection to the fc fabric.
This is the only server in our environment where we have this issue. I remember we had this once on a windows 2003 machine where snap drive wasn't installed. The installation of snap drive solved this issue. I have a virtual 2008 server FC Host utils installed snap drive installed I see the lun only once. The same setup on the physical machine shows the lun twice.
i think i have an idea why the VM didn't have a problem.
The VM is probably accessing VIA iSCSI. the other machine is probably accessing VIA FCP. with FCP the VTIC is a valid path with iSCSI it isn't. Again, this is all supposition since i don't have a diagram but thats how it played out in my head.
