Hi, I am giving a Mac Mini server a clean install this week. At this point the two HDD's are not a copy of each other, however I would like to make sure the 2nd HDD will become a clone of the first one. So in case if disk failure it is easy to switch to the 2nd Hard drive. What is the best way to perform an clean install for the Mac Mini and how can I accomplish to clone the HDD's. Besides, the Mac Mini is not connected to an external screen. When clean installing the Mac Mini it will probably not be possible to open up a screen share? There are several other Macs in the network and I also have a thunderbolt cable available. Is it possible to connect the thunderbolt cable to the Mini together with a Macbook or possibly an iMac and use the macbook as external display? thanks in advance.
