I have a client whose old server has just stopped working and the manufacturer has diagnosed mainboard failure and have put a new one in the post which arrives today.
My question is that the server has a muli-disk RAID array but I don't know what RAID system was used (i.e. RAID 1 e.t.c.).
Once I replace the mainboard, how would I go about rebuilding the raid array without choosing the wrong option and without losing the data which is vital? Would the raid controller just detect what sort of array was already in place from the hard drives themselves?
