This checklist shows the sequence of tasks that you use to add one or more disks to an existing input/output adapter that has built-in device parity protection. Use this checklist if you plan to protect some or all of the new disk units with device parity protection. If you do not plan to protect any of the new disk units, use Checklist 2: Add disk units without device parity protection.
You can use this procedure whether you have mirrored protection on your system because you start device parity protection before you add the disk units to a disk pool.
