I tried with Intel X25-M 160 and 80 GB and a X25-E 64 GB (only because that
was what I had in my drawer). I am not sure which one of them that made it
lock up, maybe it was all of them.

Since the head is a X4150 with 8 slots and a plain LSI SAS HBA, I put
them in there instead and went ahead.

Ok, thanks for the information, good!
So it just changes the mpxio-disable="yes"/"no" in the <driver>.conf files?

That is almost what I do, except that I only have one HBA.
We haven't seen many HBAs fail during the years, none actually, so we
thought it was overkill to double those too. But maybe we are wrong?

Thanks! I will try to update the firmware in the chassis and see what that
gives. I really hesitate to use HP HBAs - if they have changed anything
from the OEM firmware it is hard to tell how compatible they are.
