I have a SBS 2003, Dell Poweredge 2850 server that has 2 SCSI drives on a perc 4i RAID controller. I would like to know if anyone has performed the following operation that I am going to describe.
I purchased a 3rd identical drive to use as a backup. If I went into the Dell array manager software and forced one of the 2 disks in the array to offline and then removed it. Then, installed the new disk in and allowed the system to sync the new drive into the array. If, after installing updates Service packs etc and something went wrong, could I power the system down, install the orignal disk I removed from the original array and boot up from that drive? Am I asking for trouble? I am a little reluctant to even test it because I am not sure that if I reset the RAID controller to force bootup from the single drive if that will cripple the working pair of drives data?
