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.
