Rebuilding a Disk Array
Notes
• You can add physical drives to a RAID 50 or RAID 60 array
but you cannot change the number of axles.
• If you add an odd number of physical drives to a RAID 10
array, it will become a RAID 1E array by default.
When you rebuild a disk array, you are actually rebuilding the data on a
replacement physical drive.
