4. After RAID online migration is finished, use Mirror Split on the
Primary OS (Array 1) to split it into 2 x RAID 1 arrays. The split
array is shown as “Array 3 Primary OS.”
5. Rename Array 3 to Backup OS with a date for easy identification.
The array is then the new backup operating system array.
The aforementioned steps of system split, system swap and system repair
assure that no matter what damage is caused to the system, it can be
repaired for immediate service after being set up, without further configu-
ration. This further increases availability of the system and minimizes
system down time caused by accidents and hardware failure.
