I re-read alexveres' first response to Chis_L's request for more info, and now I think I understand what is happening here. I must ask alexveres, do you understand the difference between capturing a BESR image and cloning a hard drive? The two processes are world apart different. The copy drive function should only be used in situations like copying the data from a non RAID drive to a newer and larger non RAID drive. I think the situation can be salvaged, but I'll first outline how I would have approached it.
1. Capture a BESR image to either a network location or external hard drive and verify the image with Recovery image browser
2. Remove the old RAID controller and install the new RAID controller.
3. Initialize the new RAID configuration.
4 Boot the server with the System Recovery Disk and restore the system from the image previously captured. Would definitely use the Restore AnyWare option, as well as options to restore the drive signature and MBR.
Hopefully the single drive the original RAID 5 array was cloned to is still intact. I'm also assuming that you are working with at least BESR 8.5. Otherwise, you will need to do an "Install in place" of the OS to salvage this. Assuming the conditions previously outlined
1. Mount the single hard drive that contains the cloned data back into the server.
2' Boot the server with the version 8.5 SRD
3. Capture a BESR image of the single hard drive that contains the cloned data to a network location or another external drive. If this drive contains multiple partitions, an image of each partition will have to be captured.
4. While still in the SRD session, restore the image(s) previously captured to the new RAID five array. Would definitely use the Restore AnyWare option, as well as options to restore the drive signature and MBR.
5. Shut down the server, remove the single drive and reboot.
I can't guarantee this will work, but from my chair, it seems like the best approach to get this server working again. The previous attempt to transfer the data was a very different departure from how this product is normally used. Hopefully this is not a production server and was just a practice server in a lab setup.
Best of Luck.
