[CentOS] slightly off-topic, RAID program for on-board SAS 2308-4i ?

Does anyone know what program can be used to query the RAID status
from the OS for an on-board LSI SAS 2308-4i?

On this page:

http://docs.avagotech.com/docs/12351997

there is a curious note on the left that reads:

"Integrated MegaRAID support available upon request"

After one mostly fruitless round of chatting with LSI/Avago/Broadcom
and one completely fruitless round of chatting with HP, I found 
confirmation under the storage section here:

http://www8.hp.com/us/en/mpc/workstations/product-detail.html?oid=5225041#!tab=specs

It looks like HP didn't "request" MegaRAID support, so MegaCli and
StorCli don't see anything and neither does lsiutils (nor hpacucli,
tried just for a laugh).

Any clues appreciated. Thanks for your time.

Cheers,
Zube
