Lost RAID1 configuration on Intel Embedded Controller

We have an Intel 1200 BTS motherboard using the LSI ERST2 Controller.

We had 2 x 1TB drives in RAID1 with an OS installed and  2 x 3TB drives in RAID1 as  secondary storage. We disconnected the 2 x 3TB and replaced the 2 x 1TB with SSD's. We recreated the RAID1 virtual disk on the SSD's and then reinstalled the OS.

Once installation was complete we shut down the server and reconnected the 2 x 3TB drives making sure they were connected to exactly the same ports they were before anything was disconnected.

On the first boot we saw a splash screen saying there were previous RAID configurations found but the timestamps were inconsistent. Once it moved past this point the OS booted. Using the Intel RWC2 I could see both of the disks but they both reported "Unconfigured Good" as their status as if the RAID configuration wasn't there any more.

Has the RAID config somehow been wiped from the drives and is there any recovery procedures anyone can recommend to get the virtual disk back up and running?

Did you try CTRL +E during POST to see if you could import the config from those drives?

It could be possible that some of the info was stored on the original 2 x 1 TB drives, although I would think that would be a dangerous move on Intel's part.

It may also have disabled the options in the BIOS.  Press F2 at boot and make sure that RAID is enabled completely under Advanced>Mass Storage or ATA controller configuration.

Just throwing stuff out there!  LOL

Yes we made sure that was enabled and built the array out of the SSD's.

After a lot of stuffing around we pulled one disk and connected them directly to a desktop motherboard. This allowed us access to our data which I copied to another disk.

Gotta love RAID1!

RAID anything else and we would have been in trouble!!!
