SAN not presented.

I have a linux server that does not receive the SAN presented.
below is some interesting output from dmesg

qla2300 0000:06:01.0: region #0 not a PIO resource (0000:06:01.0)...
qla2300 0000:06:01.0: region #0 not an MMIO resource (0000:06:01.0), aborting
qla2300: probe of 0000:06:01.0 failed with error -1
qla2300 0000:06:01.1: region #0 not a PIO resource (0000:06:01.1)...
qla2300 0000:06:01.1: region #0 not an MMIO resource (0000:06:01.1), aborting
qla2300: probe of 0000:06:01.1 failed with error -1

further troubleshooting is attached.

Any assistance will be highly appreciated.
How can I verify if this is a hardware/software/driver problem?

Regards
Ken

could you provide a little more details on your SAN(including array)environment?

It's the Server hardware is BL25p and the SAN is the MSA1500 the server is running Red Hat 3.4.4-2.
One of the blades works fine and can see the san presented. The other does not.

Looks like a low-level hardware problem or some parameters on the motherboard are incorrect. I would carefully dis- and then reassemble the blade to see if the problem goes away. Consider running a SmartStart disagnostic.
