storage array, the enclosure mode switches of the
MD1200 Series expansion enclosures must be set
to the Unified-Mode position.

the MD1200 Series expansion enclosure. Changing
the switch setting after the expansion enclosure is
turned on has no effect on the enclosure
configuration until the expansion enclosure goes
