Installing onto SCSI [hw] RAID0 Array

Lactic

Howdy.

I've got a Compaq Smart 2-SL SCSI/RAID controller with four drives set up in a RAID0 array, created in Windows using the compaq controller software I found. It gives the logical drive's geometry as 255 heads, 63 sectors/track and 8855 cylinders.

When I go to begin installing Gentoo, I setup my network just fine, "modprobe cpqarray" [works], "modprobe sr_mod" [works], "modprobe sr_mod" [works], per gentoo install instructions.

When I go to set up partitions is where I run into problems. I get errors when I try each of these (usually "You will not be able to write the partition table" or some such): fdisk /dev/hdc (This I assume is the array, as I only have one IDE hdd in here, unless that's my cdrom showing up...), fdisk /dev/ida/0, fdisk /dev/rd/c0d0. (I think those are what I tried...) I had no /dev/scsi devices, no /dev/sd? either.

One or two of these does work and let me into fdisk, but when I create a partition, it only asks what head [??] to start at, and then finishes adding. When I print the partition table, it shows the partition starting and ending at head (maybe it's sector...) 1. Needless to say, I don't need a 75GB boot partition.

Any ideas?

ok. fdisk /dev/ida/c0d0 gives me the "you will not be able to write the partition table", then "Unable to read /dev/ida/c0d0" and exits.

/dev/hdc is my cdrom, so that's out. /dev/rd/? (contains rd0-rd15 and initrd) lets me into fdisk, tells me sector size is 1024, not 512 (I think it's actually 128, maybe 512 though) and shows the geometry as 1 head, 22000 sectors, 1 cylinder...

all very odd.

*bump*

Anyone have any ideas about this?

Are none of the other raid related threads helpful?

when you first do the modprobe stuff do you modprobe sd_mod?

you listed sr_mod twice in your original post so i figured one was suppose to be sd_mod?

what does fdisk tell you when you enter /dev/sda as an argument?

Yes, I did modprobe sd_mod. And there are no /dev/sd* devices listed.
