I have a Compaq Proliant DL380 (1st generation). It has four SCSI disks connected by the integrated RAID controller. I have three disks arranged in a RAID 5 configuration as one logical disk, with the fourth disk used as an online spare.

I am trying to install Gentoo Linux 2007.0 on it. The Gentoo install CD seems to pick up the hardware fine. The logical disk shows up as /dev/ida/c0d0.

How do I refer to this device in grub-speak? I have tried root(hd0,0) (sd0,0), (c0d0,0), and many other things to no avail. I also tried using tab completion for root( and setup( ... no luck there either.

What would I call /dev/ida/c0d0 in the grub.conf file?

Thanks,
mmmmtmmmm

If I compare the device /dev/ida/c0d0 with a CCISS device then this is Controller first with disk 1 which is equivalent to hd0, but as you say its just what the OS see ..I think the partition thingi is missing here.

Goto hp and get smartstart 5.5 . This is a iso image and it is the ONLY way to configure a Compaq system. It is free or you can have it shipped to ya.
