Resetting the service processor

Use this procedure to reset the service processor.

Note: Use this procedure only under the direction of your next level of support or your hardware service provider. During this procedure you will be powering off the system and removing and reapplying AC power.
  1. Inform anyone using the server that it will be shut down.
  2. Stop all applications that are running on the server.
  3. Stop the operating system and server by choosing from the following options:
    • If you have an HMC, shut down all logical partitions and the server. For instructions see Powering off the managed system. Then continue with step 6.
    • If you do not have an HMC, continue with the next step.
  4. Log in to the system as a user with the authority to run the appropriate shutdown command.
  5. At the command line, enter one of the following commands:
    • If your system is running AIX®, type shutdown
    • If your system is running i5/OS®, type PWRDWNSYS *IMMED
    • If your system is running Linux®, type shutdown -h now
    These commands stop the operating system. The system power turns off, the power-on light begins to slowly blink, and the system goes into a standby state.
  6. Unplug the AC power cord and replug it back in.
  7. Start the server. The service processor is reset. This ends the procedure.
