Okay, after much frustration I've gotten OES2 (obviously SLES 10 SP1)
32-bit working with our HP BL460c blades and the QMH-2462 Qlogic boards
to work.

The main issue was that HP does NOT support using the native kernel
drivers, so I had to download and compile the HP drivers.

And then figure out how to setup the multi-pathing and boot from san.

Got that working.

However, it seems the default driver from HP has load balancing setup
where the LUN's are spread evenly across both paths.

My question is:

1) Is this supported with OES2?

2) Is it supported with NSS volumes on OES2?

I have tested failover and failback with plain Native Linux (ext3) and
that works fine.
