I did create the device mapper for multipathing but while testing failover is not working. So my concern is with the hba driver since I am seeing more than expected.
Thanks

Hi Rajagopal,
Do you mean to say this is typical and is resolved after we use device mapper multipathing?
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....
