Goal

Solaris[TM] device paths and messaging reference the ID of a given processor (in /var/adm/messages, console logs, core files, OBP probing, etc.).

This document provides the cpuid cheat sheets for the Sun SPARC Enterprise[R] M3000/M4000/M5000/M8000/M9000 (OPL) Servers.

On the Sun SPARC  Enterprise M3000, there is only one domain and only one LSB (00).

The processor numbering is based on the Logical System Board mapping therefore, the numbering is common to the Mid-Range Servers (M4000 + M5000) and High-End Servers (M8000 + M9000).
This document explains how to correctly decode an ID (cpuid and portid) to the physical location within this platform.

By correctly mapping this ID to a physical location, we know that we are servicing the right component to resolve a hardware problem. An incorrect mapping could result in replacing and/or servicing the wrong component and could cause further outages or problems on the platform.
