OH. its a very good idea to verify the driver is at the same revision
level as the firmware. not 100% sure how you do this under CentOS, my
H220 system is running FreeBSD, and is at revision P20, both firmware
and driver. HP's firmware, at least what I could find, was a fairly
old P14 or something, so I had to re-flash mine with 'generic' LSI
firmware, this isn't exactly a recommended thing to do, but its sure
working fine for me.
