<html><body> I have seen this with IBM HostRAID as well, and in addition when I try to install RH with a driver disk with "linux dd" it accepts my a320 driver then superseedes it with the native scsi aix27xx driver and I my host raid fails. The way I have gotten around this is to install on sda and then remove the 27xx driver and install the a320 then reboot and the raid works. Verify that the driver you have installed is up and runnng and that the native rhdriver hasent taken over.

The specific model of server is a 6024H-TR. The motherboard has two different SATA RAID controllers onboard. It's a little bit confusing, because the BIOS for both of the SATA RAID is an "Adaptec Embedded HostRAID v2.2-1.2005". However, the motherboard documentation on SuperMicro's website indicates that one SATA RAID is a Marvell 88SX6081 controller, and the other is a 6300ESB controller. We have set up two boot drives in RAID1 using the firmware from these controllers, and on boot the RH CD detects the drives using the libata ata_piix driver, but this driver doesn't recognize the RAID capabilities of the controllers and so the drives show up as two distinct /dev/sda and /dev/sdb drives. Can anyone provide pointers on how to get a 2.6 kernel working with RAID 1 on either of these controllers? -- Roger J.
