SCSI Address Mapping

The driver emulates six SCSI buses per HBA to map all 126 possible AL_PA to Target

IDs.

The first bus is a dummy bus used to delay the initial inquiry scan until after discovery

completes. The 31 target IDs per bus are then mapped to either ascending or

descending SEL_IDs (based on the ScanDown registry parameter).

NOTE: The driver uses the first bus if the parameter MapBus0=1 is used.

In a fabric (switched) environment, devices are initially created in the order that they

are returned from the Simple Name Server (SNS). Once created (at boot), the devices

continue to be tracked based on:

–WWPN:HardAddress=0;MapNodeName=0

–NodeName:HardAddress=0;MapNodeName=1

–D_ID:HardAddress=1; (MapNodeName=don't care)
