Solution 1003335.1 : Sun Fire[TM] 12K/15K: Cheat Sheet: CPU and Domain Signatures

Applies to:

Sun Fire 12K Server
Sun Fire 15K Server
All Platforms

Goal

The purpose of this document is to define the CPU states and their derived domain states in the Sun Fire[TM] 15K.

Solution

During the life of a domain, dsmd monitors the domain state to determine if an Automatic System Recovery (ASR) action (panic recovery, reboot, etc.) or another action (timeout counters, heartbeat detection, etc.) is required.

The CPU signature state is used to derive the domain state. Some CPU signatures result in a change in the overall domain state and some do not. The table below summarizes the CPU signature states, the derived domain state (if any), and other actions/event dsmd triggers. Note this is not an exhaustive list of all CPU signature states.

CPU State               Domain State            Description/Notes
=====================   ====================== ===========================
OBP/INIT/NULL           OBP/INIT/NULL           OBP is booting

OBP/RUN/NULL            OBP/RUN/NULL            OBP is running

OBP/CALLBACK/*          OBP/CALLBACK/*          In OBP Callback

OBP/LOADING/NULL        OBP/LOADING/NULL        Solaris[TM] is loading

OBP/BOOTING/NULL        OBP/BOOTING/NULL        Solaris is booting,
                                                timeout detection is
                                                active

                                                a panic timeout, so watch
                                                for XIR resets/dumps.
