IC7-G And Intel RAID problems

I have a IC7-G motherboard.
It has two SATA PORTS 0 & 1 (Intel)
I have one Seagate 120Gbyte HDD on each Port (therefore two in total).
I have a RAID 1 (Mirror) volume comprising of these disks.
One of the disks (PORT 1) has failed.
The other disk (PORT 0) is still good and the system boots.

I want to know how to recover the RAID 1 Mirror usign a new disk.

I have a brand new disk which is identical in everyway to the original two.
The RAID 1 Volume contains a Windows XP Pro SP1 system.

I have tried the following.

If I unplug the failed disk and attach the new clean disk then the system shows me that I have a RAID 1 volume with one good and one missing volume. It also shows I have a NON RAID disk attached. Both the RAID 1 volume and the NON RAID disk are shown as bootable. However the system will not boot I am guessing as both bootable it does not know what to do.

If I remove the new disk and put back the old failed disk the system boots happily.

How do I repair the RAID 1 Mirrored volume please.

The Intel BIOS RAID only allows Create / Delete or reset disks to non raid. All of which is fairly useless.

If I could get the system to boot with a clean disk in it I could use the Intel RAID utility under Windows XP to rebuild but the thing wont boot.

How do i get it to boot with the new disk. Any ideas please.

Regards,

Graham

Well ... according to Intel's documentation, you do the rebuild from the Intel Matrix Storage Manager from Windows (as you know, since you mentioned doing the rebuild that way)  ==> of course, that's difficult if you can't boot !! :-)

So ... Do you get a message from the Matrix Storage ROM at boot time about a failed or degraded array ??   Are you sure there's no option that will allow the system to boot at that point??    What message are you getting that shows two bootable volumes?   .... is there any option at that point to select one to boot from ?

Finally, according to Intel's documentation, there IS a way to rebuild the array from the BIOS Option ROM ... by pressing Control-I during POST and following the prompts ==> see Method 3 here:

There are no options on the boot it just hangs.

The RAID BIOS info screen which pops up prior to OS boot tells me that both volumes are bootable but no options in there to select between them or in the std BIOD selection.

Intel Matrix storage is for newer chipsets I think. This board has ICH5 (not ICH5R) so I dont think I can use Matrix Manager but I could be wrong its not 100% clear on the Intel site.

When you use CTRL-I the only options are those I stated (I dont know who makes this stuff but their choice of options are shall we say interesting ! ;o)

1. Create Raid Volume
2. Delete RAID Volume
3. Reset Disks to Non RAID
4. Exit

Do you think they might have had an option for er something like REDUILD RAID array ??? It would to me seem sensible given thats why we have RAID isnt it ??? LOL

My real problem I guess is how to boot so i can use the Intel Utility n XP.

I agree it's (shall we say) silly to not have a simple REBUILD option => rather defeats the purpose of RAID !!

My best guess -- and it IS a GUESS -- is that you need to "Create RAID Volume" ... and that you will be given a choice as to which volume to build the mirror from.   But I would NOT do that without a complete IMAGE of your current disk.

What I would do at this point:

(1)  Replace the disk that lets you boot okay.

(2)  Boot to an imaging program and make a complete image of your "drive" (RAID array)  [I would use Boot-It NG, but any program that will work with the RAID array is fine]

(3)  THEN shut down and replace the failed drive with the new one.   Go ahead and try the "Create RAID Volume" selection and see if it does indeed allow you to rebuild correctly.   IF not, I'd simply reset the disks to non-RAID;  then boot again and create a new RAID volume (this will, of course, destroy all of your data); and then restore your image to the new array.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

... just re-read my last post & realize #1 is not clear ==>  "Replace the disk that lets you boot okay" means to "Re-install the disk that lets you boot okay" :-)

The answer provided did give a workaround but it is not the answer i was looking for.

I am still looking for a solution as I dont want to do image copies everytime.

I feel like i should award something but its not the answer so the full 500 points offerred is a little much.

I want to be fair - thoughts please to make a fair position for all.

Graham

You shouldn't have to do image copies everytime => doing an image NOW is a good idea as a safeguard against losing everything if the direct rebuild doesn't work.   You COULD simply try it without the image ... but if you lose everything in the process you'll certainly wish you had an image :-)
