Generating a BMC dump on OpenBMC POWER9 processor based systems

How To


Summary

This document will guide you to generate a BMC dump on the OpenBMC POWER9 processor based systems: 8335-GTG, 8335-GTC, 8335-GTW, 8335-GTH, 8335-GTX and 9183-22X.

Objective

Generating and providing a BMC dump on the OpenBMC POWER9 processor based systems when requested by IBM supports.

Environment

To generate the BMC dump on the OpenBMC POWER systems we  use IBM OpenBMC tool.
The  tool is used to interact with the OpenBMC on the 7063-CR2, 8335-GTG, 8335-GTC, 8335-GTW, 8335-GTH, 8335-GTX, and 9183-22X products.
  • The tool can be installed on a Linux partition if one of the system partition is up and running, or from another Linux system (or partition) that have a valid connection to the BMC we want the dump for.
       To do so you can follow the document Scale-out LC System Event Log Collection Tool in section "IBM OpenBMC tool" all the steps and pre-requisites are listed.

Steps

  1.  Check if the network connection is operational by ensuring that pinging the BMC’s IP address is successful.
  2. Run the command   
    python3 openbmctool.py -H <bmc IP> or <bmc hostname> -U <username> -P <password> dump create
      when on a MacOS laptop, or command 
           
    openbmctool.py -H <bmc IP> or <bmc hostname> -U <username> -P <password> dump create
    when using a Windows laptop
  3. When you have the successful message, you are back at the prompt (below an example on MacOS)
[prompt]% python3 openbmctool.py -U **** -P **** -H xxx.xxx.xxx.xxx dump create
Attempting login...
Dump successfully created
User root has been logged out
[prompt]%
Once the dump have been generated, IBM suggest to collect the service data with the following command:
 
openbmctool.py -H <bmc IP> or <bmc hostname> -U <username> -P <password> collect_service_data
The collect_service_data option will collect all the dumps in addition of some other files such as 
- ledStatus
- parsedSELs
-SELshortlist
-sensorReadings
Then a .zip file is generated with the format 
[bmc ip]--[Date-Time-Hour]_1.19_openbmc.zip
Send the file to IBM support for review
