Goal

Description

This document describes how to check if the is system is powered on via ipmitool, Service Processor Web GUI, Service Processor CLI and if you are local to the server.

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Sun x86 Systems

Symptoms:

Server powered off, need to investigate why

Solution

Steps to Follow

Verifying system power status via ipmitool

Run ipmitool from a remote system to the Service Processor with the command shown in the example below. The resulting output will indicate whether power is on or off.

If the status is off and you expect it to be on, then refer to How to check why the system powered off, on Sun X64 servers. (Doc ID 1002941.1) to investigate further

# ipmitool -I lanplus -U root -H  chassis power status


Chassis Power is on

Verifying system power status via the Service Processor Web GUI

Integrated Lights Out Manager (ILOM) and Embedded Lights Out Manager (ELOM) based Service Processors provide an easy-to-use web interface for managing the platform. Point your web browser to the Service Processor IP address or resolving DNS hostname, and enter your login credentials when prompted.

After you have logged into the Service Processor, click "Remote Control" tab then Click "Remote Power Control" tab.

This contains the status of the platform, for example: Host is currently on

Alternatively, click the "System Monitoring" tab, then "Summary" tab where 'Power Status' will be shown.

If OFF and you expect it to be ON, then refer to How to check why the system powered off, on Sun X64 servers. (Doc ID 1002941.1)

Refer to the ELOM or ILOM Administration Guide for your platform and firmware version. Also see the ELOM or ILOM Administration Guide Supplement for your platform:

Verifying system power status via the Service Processor CLI

Log in to the Service Processor via SSH:

# ssh -l <USERNAME> <ILOM IP Address>

And use one of the following commands to determine the platform power status

ILOM

-> show /SYS
...

   /SYS
   Properties:
   type = Host System
   ipmi_name = /SYS
   product_name = SUN FIRE X4440
   product_part_number = 602-4057-01
   product_serial_number = 0812ZYX001
   product_manufacturer = SUN MICROSYSTEMS
   power_state = On

ELOM

-> show /SP/SystemInfo/CtrlInfo

  /SP/SystemInfo/CtrlInfo
    Targets:

    Properties:
        PowerStatus = on

V20/40z:

$  platform get power state

On

If OFF and you expect it to be ON, then refer to How to check why the system powered off, on Sun X64 servers. (Doc ID 1002941.1)

Verifying system power if you are local to the server

Verify the state of the Power OK LED from the front or rear of the server. LED states may vary slightly between platforms, but generally:

STEADY GREEN ON - System is powered on.
SLOW BLINK GREEN - System is powered OFF, but standby power is present.
NOT ILLUMINATED (OFF) - Server main power and standby power are off (no AC power, not plugged in, etc).

If the system is powered OFF and you expect it to be ON, refer to How to check why the system powered off, on Sun X64 servers. (Doc ID 1002941.1)

For further Information about LED states, refer to the Server Service Manual or Server Diagnostics Guide for that particular X64 system:
