hdparam/fio on ProLiant BL460c Gen8 (Smart Array P220i)

[bigsuport]

Hi,

the host is running Scientific Linux 6.5, kenrle 2.6.32-504.1.3.el6.x86_64. The RAID is recognized by the system and it's using hpsa driver:

 and the disc and its partiotins are propertly shown:

But when I run hdparam -I it gives an error:

# hdparm -I /dev/sda

/dev/sda:

Why is hdparam not able to print disc information?

Also, anyone has run fio over this disk? any result that I could use for comparing?

Many thanks in advance,
