Starting device parity protection
The best time to start device parity protection is when you add new or non-configured disk units. The Add a disk unit or disk pool wizard has steps for including disk units in a parity set and starting device parity protection.
Notes:
- All disk units in a parity set must be the same capacity.
- Systems with IOAs released before V5R2 of OS/400®, the minimum number of disk units for a RAID 5 parity set is 4. The maximum number of disk units in a parity set is 10.
- Systems with IOAs released after V5R2 can have a minimum number of 3 disk units for a RAID 5 parity set. The maximum number of disk units in a parity set is 18.
- The minimum number of disk units in a RAID 6 parity set is 4. The maximum number of disk units in a parity set is 18.
