Description
This document describes what to check if systems appears to be powered off and you expect it to be ON via ipmitool and if you are local to the server.
Symptoms:

System has lost power, system does not have any power



Steps to Follow
using ipmitool

Note: This document uses the optional service processor SMDC (Service Management Daughter Card) to get information of the system with the help of IPMI (Intelligent Platform Management Interface), therefore this Card needs to be installed and configured to follow the steps within this document.

To get information on how to install and configure the optional SMDC, please refer to the Sun Fire X2100 Server User Guide, Part No. 819-3721, Appendix C, "Using the Optional Service Processor"

Available at:

http://www.oracle.com/technetwork/documentation/oracle-x86-servers-190077.html

If the chassis has no power, the Service Processor will not function as it requires Standby Voltage. If this is the case then examination of the local server is required See "3. Verifying cause of NO power if you are local to the server" below.

If you can communicate with the Service Processor, then AC voltage is available to the server. Use the following to gather the status of the platform and to gather possible reasons of the outage using ipmitool.

There are some conditions that trigger the BMC to issue a shutdown request:

  • An over-temperature condition for more than 1 second.
  • Multiple fan failures.
  • CPU thermal trip

The fault conditions that will trigger a shutdown are:

  • Power supply have failed or have been removed.
  • A power supply has been out of spec for more than 100 mS.
  • An over-temperature condition has occurred

1. Gathering possible reasons of the outage using ipmitool

  • Use the following common ipmitool commands to gather further data as to the possible reasons for the platform state. These would be useful if you need to report a support call.
      ipmitool -I lan -H <ELOM IP or Hostname> -U <ELOM User name> sel elist 
ipmitool -I lan -H <ELOM IP or Hostname> -U <ELOM User name> sel info
ipmitool -I lan -H <ELOM IP or Hostname> -U <ELOM User name> sdr list all info
ipmitool -I lan -H <ELOM IP or Hostname> -U <ELOM User name> fru print
ipmitool -I lan -H <ELOM IP or Hostname> -U <ELOM User name> sensor

See <Document: 1009698.1> for further information on Intelligent Platform Management Interface (IPMI).

2. If the system will still not power on even if AC is available

There could be an environmental issue that might be the reason that the server will not power on or remain on. Check environment and event logs for possible causes.

3. Verifying cause of NO power if you are local to the server.

  • If the Power LED on the front or back of the system is OFF, please Ensure that an AC power cord is plugged into at least one power connector on the rear of the server and into an working AC power outlet(s).
  • If have still have no Power LEDs activity and the AC power cords are connected to the system, engage a qualified electrician to check the AC voltage on the power cords.

For further Information about LED states refer to Sun Fire X2100 Server Getting Started Guide, Part No. 819-3720 Chapter 1.6, "Powering On the Server"
