AIX/HMC Unable to boot with error AA00E158 with HMC

How To


Summary

Unable to boot an LPAR and stuck on error AA00E158.

Objective

Getting around an LPAR not booting due to error AA00E158.

Environment

PowerVM/VIOS
AIX
HMC

Steps

  • The first scenario is to check the profile of the LPAR causing the issue, and make sure it is not set to boot in SMS.
  • The second scenario is to check the number of partitions you have versus how many partitions are allowed as per the limitations in your environment, such as your PowerVM/VIOS Edition (PowerVM Standard Edition/PowerVM Enterprise Edition/IBM® PowerVM, Linux Edition) in case of a PowerVM/VIOS configuration.
  • The third scenario usually takes place after a power outage, you need to exit SMS and reboot the LPAR and it should boot successfully. More information about this scenario and how to fix it on;
