a) If no parity disks at all, permit start/auto-start for any present data disks.

 

b) If parity1 present and valid (but parity2 not present), permit start if parity is correct, and all the data devices are correct, but just in different slots.

 

If parity2 is present and valid, all devices must be present and in their correct slots, no way to get around that one.
