If these are SCSI drives you would be better off if you started out with 8

3 drives: Raid striping is across only 2 drives. Ultimate performance
killer. Legendary. Across multiple OS's, not just IBM i. Google 3 drive
raid set.
4-7 drives: Raid striping is across 4 drives.
8 or more drives: Raid striping is across 8 drives.

Can you see the difference there?

Can you start raid, add drives and balance data to ASP1 with the system
up,
or do you need to it in a controlled environment using SST/DST.
