Have Hardware RAID1 but Redhat install sees two disks

[stevenriz]

Hi this is strange. We have an embedded Adapted controller on the mobo and we created a raid 1 mirrored disk using two drives. One is a 40gb and the other is an 80gb. We of course selected the 40gp to be the primary knowing full well that the resulting partition will be 40gb. When we return into the Adapted bios we see the raid1 partition at 37gb which seems fine. Now the issue is when we boot to the redhat installation. When doing your partitioning, it shows sda AND sdb of 38gb and 79gb respectively. I don't get it. any thoughts? Do you think it;s the fact that we have two different sized disks? I've done this before with two separate disks without issues... What do you guys think? Thanks!

Has the RAID controller fully synced the mirror?

what does fdisk say?

The raid build completes successfully and during bios splash screens, it shows one logical drive. It seems redhat can see right through that like a cheap mirror, no pun intended. I haven't loaded redhat completely to run an fdisk, it is when the configure partitions screen comes on where I see both disks, model numbers and everything!

Here is all I found on the subject so far...

Here is the manual here which I am sorting through now. It is embedded on a Super Micro X6DHE-XG2 motherboard.

I'll let you know if I find anything. Thanks for the reply.

I've seen cases (both fedora & mandriva) recently where during installation, the partitioning tools see the Raid array and the drives seperately. sda was the array, sdb & up were the individual drives (mandriva actually showed more drives than actually were there). However, when partitioning & installing these I was carefull to only work with the array, and everything went fine & you can't see the individual drives from inside the installed system. Anyway, take another look & see if sda might actually be the raid array.

Yes I am configuring only sda and installing only on sda. Will report back what I find. Thanks!
