APPENDIX A

Mapping Device Path Names

This appendix describes how to map device path names to physical system devices. It contains these sections:

Device Mapping and Logical System Board Numbers

CPU Mapping

I/O Device Mapping

Device Mapping and Logical System Board Numbers

The physical address represents a physical characteristic that is unique to the device. Examples of physical addresses include the bus address and the slot number. The slot number indicates where the device is installed.

The logical system board (LSB) number affects both the processor numbering and the I/O device paths in the server. Physical resources are assigned to LSBs in the specified domain using the setdcl command. It is the LSB numbers that the Solaris OS uses.

CPU Mapping

Each LSB has a bank of 32 processor numbers assigned to it. Each processor has two cores, and each core has two strands.
