devNum1
user number. For NSE device, this is the device number and this should follow the following
calculation: (stageNum * MAX_DEPTH) + depthNum where stageNum denotes the stage
number, depthNum denotes the depth number of the device, and MAX_DEPTH denotes the
depth of the space stage. Both stageNum and depthNum starts from zero. For instance,
devNum1
devNum2
For NSE device, this indicates whether the NSE device is a secondary device in a doubled
NSE/SBS fabric configuration.
devNum3
altMuxVal
doubled SBS/NSE fabric configurations. If this field is zero, the default control value is
selected by the CSD (the control value depending upon the field
However, user can override this value by supplying a non-zero value for this field. This value
should not be arbitrary and should match the underlying hardware.
isLocal
microprocessor that also runs the CSD. If a device is local, the CSD will invoke any
underlying device driver API, if necessary, for a particular operation; otherwise, CSD treats
the device as a logical one, or remote, and no API calls will be made to the underlying device
driver. The
field. In other words, setting the field
will be ignored by the CSD which will treat the device logical in that situation.
