OK I'm not very familiar with raid so I apologize in advance if I don't explain this properly.
I have a Dell PE2850 I've been using for a few years as a web server. Recently it complained that one of the drives in the system raid 1 array was failing (though hadn't failed yet). Not wanting to risk the second drive failing I took two brand new 146GB U320 drives over to the data centre to replace the aging 36GB U320 drives.
The configuration at this point was two 36GB drives in slot 0 and slot 1, these two drives were raid 1. In slot 2 there was an extra 36GB drive that wasn't in use (wasn't initialized or part of a volume).
I went into the Dell server admin application and off-lined the spare drive and off-lined the failing drive in slot 1. I then put the 146GB drives into slots 2 and 3 (1 is empty now). I ran the create volume wizard and put the two 146s into a raid 1 volume. At this point everything is ok.
I got the Norton Ghost disc out (I was planning to mirror the OS to the new volume) and rebooted the server. At this point it says that none of the drives are responding check connectors, cables and power. I did and all the drives were green.
I asked my friend and he said it probably didn't like the fact there was nothing in slot 1, so I moved a 146GB from slot 3 to slot 1 and it now says there are no logical volumes.
When I go into the volume configuration menu it shows all the drives are ready.
How do I get it to recognize the original system volume drive in raid 1 so that I get my data back?
I appreciate any advice so I can avoid this problem in the future.
