I have a Mac mini that had OSX Leopard Server on it. We installed Lion Server on it when it first came out and put it in to a small school and gave them all the details. They were having issues and asked us to sort it all out. We had no passwords so decided to re-install the OS.
This was not a very good idea. On an internet restore it keeps stalling and telling me that I need to go to the disk utility and delete the main partition. When I do this it has the two 500GB drives combined to a master stripped drive. However everything is locked and will not allow me to make any adjustments.
Is there any way to unlock these drives and allow me to reset all the partitions and Raid configuration?
