Lost RAID1 configuration on Intel Embedded Controller
Posted on 2014-01-12
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?
