I. Any configuration change is ignored

II.Physical drive change rules: no drivers accepted; in SAFE (RAID-1) mode, a single driver change will be accepted with normal driver rules (larger or equal to existing drive)

B. Upon power-up, but with no pushbutton (reset) press

I.Any configuration change is ignored

II.Physical drive change rules: no drivers accepted; in SAFE (RAID-1) mode, a single driver change will be accepted with normal driver rules (larger or equal to existing drive which must be present)

C.Upon power-up and momentary pushbutton (reset) pressed
