We have a a server with a PERC 6/i controller. There is currently a single virtual disk on that controller, it's a RAID 5 disk with 4 physical drives. We'd like to add 3 drives to the virtual disk and convert it to RAID 6, but aren't sure if we can do that without data loss.
The Dell SAS RAID Storage Manager will allow us to make this change using the reconstruction wizard, but it does not indicate if the reconstruction will be destructive...it does 'strongly reccomend' backing up data.
One additional note, the server boots off a drive that is on this virtual disk if that makes a difference.
