I'm going to get my new small business database server in a couple days. It comes with one hard drive, but I plan on setting it up initially with a 3 disk RAID 5 system. Unfortunately, the extra drives won't be in for a few days after I get the server.
I'm using a hardware RAID controller. I want to get a head start on configuration. How "smart" is RAID in this sense? If I install and configure the OS on the single drive and then add the other two drives later to have it rebuild my data across the 3 disks?
If this is possible, is there any special procedure I need to follow?
