Hi For sure no problems, I see this about everyday, the major reason is that the rh driver is not certified for use with Dell,HP or IBM for that matter, if we get a support request where I work and the RH driver is used for the qlogic card then customer must install the certified driver from the vendor, this has a lot to do with compabillity with the bios etc, I am not saying that the RH driver is bad it is just unsupported by most vendors.

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.
