System: XXXX
Non-configured device parity capable disk units are attached
to the system. Disk units can not be added automatically.
It is more efficient to device parity protect these
units before adding them to the system.
These disk units may be parity enabled and added at SST (i5/OS).
Configured disk units must have parity enabled at DST.
Select one of the following:
1. Perform any disk configuration at SST (i5/OS)
2. Perform disk configuration using DST </pre>
<p>It
is much faster to start device parity protection on the disk units at DST
before the disk units are added to the auxiliary storage pool configuration.</p>
<p>To
start device parity on the eligible disk units, do the following tasks from
the Add All Disk Units to the System display:</p>
<ol type="i"><li>Select option 2 to perform disk configuration at DST.</li>

you have PTFs loaded that enable the RAID-6 feature, the Work with Device
Parity Protection display has two options to start device parity. If you want
the disk units to be protected with a higher level of device parity protection,
the system has the appropriate hardware installed, and the PTFs that enable
the RAID-6 protection capability are loaded and applied, select the option
Start device parity protection RAID-6. If you want the disk units to be protected
with the RAID-5 protection level, select the option Start device parity RAID-5.
If you do not have the PTFs that enable the RAID-6 feature to be loaded and
applied, the Work with Device Parity Protection display shows only the option
Start device parity.</span></li>

By adding disk units before you install the operating system, you improve
your overall system performance because the operating system is distributed
across all of your disk units.
