I have one HP Proliant DL320 G5p, where for some reason, the AHCI mode is not enabled. According to server specs, it should have AHCI/NCQ capability, but ata_piix module gets loaded during bootup, not ahci module. Any ideas how to enable AHCI mode?
I'm not sure for this particular model server, but normally this is a *BIOS* setting for the SATA controller.

There are no settings in BIOS for AHCI mode, it's only possible to choose between raid and sata controller mode, i have chosen sata mode.

Check to see if there's a BIOS update on HP's site. I had some DL160s with an old BIOS with no option for AHCI mode. After upgrading to the most recent BIOS, the option was there.

Yes, AHCI support requires both hardware and BIOS to support it. Even if the hardware supports it, if the vendor has chosen not to implement it in the BIOS then there's nothing you can do. Sounds like a BIOS update will add AHCI support for you.

Yes, there was an update, changelog described changes regarding to sata2 drives should work properly with this update. Did the update yesterday, but nothing changed except the bios version number. Also tried ahci=on with no success.

That's probably why. To use AHCI you need to set it to RAID mode. Having done that, you can still use the drives independently if you prefer kernel RAID; you just have to go into the BIOS RAID setup and set the drives to JBOD mode (or something like that), by telling it to remove all RAID information from the drives.
Hope this helps Tony

I don't think so, because I have another DL320 (older G3 version) with same bios setup (sata mode). On that G3, ahci is working.

Well I haven't used that particular server, but was describing what I have found with other HP models (ML110 or DL360). On at least one of them, possibly both, I found that if I had the RAID mode turned off in the BIOS, then it only picked up the ata_piix driver, not ahci.
Cheers Tony

Ok, I've now checked up and it was the ML110 where I discovered that behaviour. The DL360 I worked with was completely different, using a driver called cciss.
Sorry for the misinformation.

CCISS is for smartarray cards, which are typically LSI Logic cards that HP has reprogrammed. these are 'true' raid cards, usually with battery backup writeback caches (although the battery module is an option), large onboard caches and their own embedded processor.
