Hard Disk not detected under Linux

[Ondrej1]

I have a XW9400 with two SAS 73 GB HDDs, which are not detected under Red Hat WS 3 Linux. I have updated the bios to the latest one. I have even tried to install Linux on just one hard disk connected, but not even one disk is detected. I have tried different distributions of linux but with the same result, even the disk was replaced with the same result. Is there any other program that I can use to detect this drive?

Probably the linux kernel don't have the storage controller module (driver) to detect the disks.

You can obtain drivers from here:

See the included documentation for information about how to use them.

Can you see the disks at the BIOS level? It maybe that you have to update the configuration and re-save in order for it to become active. This happens particularly with Adaptec SCSI controllers when you are trying to build a machine with no IDE.

Yes I can see the hard disks under BIOS. Thanks for the response.

There are many documents and driver downloads for the xw9400 under

Note that you need different drivers for the x86 vs the AMD64/EM64T version of Red Hat 3.

The SLES 9 certification notes at

include other notes on necessary BIOS settings-

ACPI Bus Segmentation and HPET had to be Disabled under Advanced > Chipset/Memory in the ROM-based Setup (BIOS) for the LSI SAS1068E 8-port Controller to function.

That may apply to recent updates of Red Hat 3 as well. Look for the ACPI setting in the BIOS menus under headings similar to the following. (This is from my notes on an xw9300.)

Advanced
Chipset/Memory
ACPI Bus Segmentation > Disable
