IIRC, in about 2008.11 I was tasked build a cluster with SAN. The san
administrator created 3 LUNs and first time around, it showed 12 LUNs.
I think it was RHEL4. Afer installation of the multipathing software
from server vendor site, we got the 3 LUNs properly. But at that time
I did sweat a little.

Of course assuming you have two qlogic, 2 san switches etc etc.

In short, most likely yes.

BTW I am not a storage administrator....
