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

OBP/EXIT/OBP_RESET      OBP/EXIT/OBP_RESET      Domain Exited OBP, console unavailable 

OBP/EXIT/FAILED         OBP/EXIT/FAILED         OBP failed to reach ok prompt

OBP/ERROR_RESET_SYNC/   OBP/ERROR_RESET_SYNC/   OBP is in sync callback to OS, timeout detection is active. This is similar to a panic timeout, so watch for XIR resets/dumps.
                        NULL

OBP/EXIT/               OBP/EXIT/               OBP exited, console

ERROR_RESET_REBOOT      ERROR_RESET_REBOOT      unavailable. dsmd will reboot the domain.

OBP/ERROR_RESET/NULL    OBP/ERROR_RESET/NULL    In OBP because of a reset error.

OBP/CALLBACK/HALT       OBP/CALLBACK/HALT       OBP running, domain halted.

OBP/*/DEBUG             OBP/*/DEBUG             OBP is running as a debugger, timeout detection is suspended.

OS/OFFLINE/NULL         */*/*                   CPU is offline.

OS/QUIESCE_INPROGRESS/  OS/QUIESCE_INPROGRESS/  OS quiesce in progress.
NULL                    NULL

OS/QUIESCED/NULL        OS/QUIESCED/NULL        OS quiesced.

OS/RESUME_INPROGRESS/   OS/RESUME_INPROGRESS/   OS quiesced, resume in progress. Heartbeat monitoring is (re)started.

OS/DETACHED/NULL        */*/*                   CPU detached. CPU is not monitored.

OS/EXIT/PANIC           OS/EXIT/PANIC           OS panicked, panic flow started. Timeout detection is suspended.

OS/EXIT/DEBUG           OS/EXIT/DEBUG           OS panicked and is dropping into the debugger.

OS/EXIT/PANIC_CONT      OS/EXIT/PANIC_CONT      Exited debugger and continuing panic flow.  Timeout detection is active.

OS/EXIT/DUMP            OS/EXIT/DUMP            Panic dump has started. Timeout detection.
