We have a customer that had their hard drive on their server fail a couple of weeks ago which left them down for a few days (waiting for a new drive). The owner wanted to go to a mirrored system on his NT4 server. My question is that there are c: and d: partitions on the drive. C: is where NT and the system software resides and D: is where the applications and databases are stored. If we make a mirrored set will we be able to mirror both partitions on the mirrored drive? If so is there anyspecial setup involved or is it just like creating a mirrored set of one partition?
