Ok, this may not be new to a lot of you or you have never even thought about it - me neither until a few days ago when I was happily unpacking our brand new Dell PowerEdge 2950.
I assemled it fast and inserted the Dell OpenManage Server Assistant CD and followed the instructions to install it, this is usually the fastest method and involves so little interaction, everything went fine and it started configuring the RAID and copying files. But after an hour or so I checked it and it was complete at 42%, and I thought lets eat lunch and give it some more time. When I got back it was still stuck at 42%. I rebooted and took the same procedure - and it stalled at 42 again.
