AIC 7902 controller does not discover new 300 Gb hdd

Hello everybody,

I am running an old linux machine (centos 5.2) as an e-mail server.
Machine is Hp proliant ml150 with  a SCSI adaptec AIC 7902.
It holds 1 simple disk - 36 Gb and one mirror of 2 X 146 Gb HDD
I need to make an HDD upgrade and I have bought 2 new HDDs of 300 Gb (HPB9 firmware) each, which I intended to install in a new mirror.

The problem is that the controller does not detect them at all.
Disks are all U320, hot swap with correct tray kit and everything.

Any ideea what to do?

Thanks,

I have contacted HP support. They said there is no BIOS update available that would solve my problem.
The only solution is to change the server.

Thanks for you support PowerEdgeTech.

Very likely your controller needs a firmware update to handle 300GB drives.

Hi PowerEdgeTech:

Easier said than done: the controller is embedded on the MB. I was unable to find any firmware update for it on HP support sites and cannot tell what to look for on adaptec site as they speak only about stand alone controllers not embedded chipsets.
It seems this is the solution but I cannot apply it...

Hmm ... what about BIOS?  Are there available BIOS updates?  I know on the Dell side, one controller would not support 300GB drives without the proper firmware, and another (using onboard SCSI/RAID) required a BIOS update for 300GB drives.
