I have a Mac Pro running OSX Server 10.5.8. A RAID was set-up initially, but I have upgraded to larger hard drives. I used SuperDuper to clone the start-up disk (including all files and applications). This went great. All works perfectly.
But now, I want to install the second drive (brand new) and set-up the mirror RAID.
My question is, when I use Disk Utility and add both drives to the new RAID, will it automatically copy/duplicate the start-up disk to the new drive? Do I use SuperDuper again for the new drive, then set up the RAID?
How do I ensure the integrity of the data on the start-up drive during the process of setting up the RAID?
Thanks.
