Troubleshooting
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 (Windows 2000 and Windows NT require the
initiator to consume one of the IDs; the default is 31) 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.
Fabric Device Mapping
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)
