There seems that there is an issue with ATCA-HPI mapping in that
Req 4.5.7.7 says that an LED with a local control state and either an
Override or Lamp test state should set the Control Mode Read Only status
to SAHPI_FALSE, however there is no atomic way to check for support
of the Override State. Therefore, there is no obvious "safe" way to implement
the spec as stated, only best alternatives. The approach taken here is to
set the Control Mode Read Only status to SAHPI_FALSE automatically if the
LED has a local control state. This will allow for issuing the Set FRU LED
state commands, however the unsupported states (Override and/or Lamp Test)
will return the specified Completion Code of CCh(invalid date field),
as stated in the ATCA base spec.
