We have HP ProLiant DL100 G2 with RAID-5 consisting of 2 logical volumes/arrays. The other day the RAID controller failed with a BSOD Fatal Hardware Malfunction (see screenshots attached). After a phys check on the controller and re-inserting it, rebooting the box shows No Boot Media present, but at least we can log into the controller configuration though it does NOT show any members now, arrays - none. If we go into Disk Utlities menu in the same controller menu, we can see all disks fine. So the controller lost the configuration for both arrays and now need to re-initialize the disks and re-create the arrays meaning it will wipe all data from the old members, which we DO NOT really want. We are expecting a new controller very shortly.
Now the question: how do we restore the old members to the new controller w/o losing the data? We dont care for the system volume (we have an image), but it's the data volume which is important (~500GB of data and no backup (I know what you think now, but the server has a secondary role and RAID-5 was sufficient redundancy for it all this time)).
Appreciate your help.
