Hi
Not sure if you have done this already but install multipath as the os sees multiple presented luns which needs to be tied up to one by multipath also do not use the rh drivers for you qlogic it's not recommended at all for any storage solutions.

Dear Per,
can you please elaborate why the QLogic kernel module shipping with CentOS 5 / RHEL 5 is not recommended? It for sure is documented to be used at least in the NetApp host utilities guide, without any warning to prefer the driver package provided on the QLogic site. And I do not see any problem using it with CentOS / RHEL 5 device-mapper-multipath on a lot of systems.

Alexander
