• What is the cause and solution for SAP error message VIRT336 - Max. LPAR Weight IIP ?

  The SAP error message VIRT336 Max. LPAR Weight IIP typically relates to issues with the configuration of the Logical Partitioning (LPAR) in an IBM Power Systems environment, particularly when using SAP on IBM's infrastructure. This error indicates that the maximum weight for the LPAR has been exceeded, which can affect the performance and resource allocation for the SAP system.
  Cause:
  
  Exceeding Weight Limits: Each LPAR has a defined weight that determines its resource allocation. If the total weight of all LPARs exceeds the maximum allowed weight, this error can occur.
  Configuration Issues: Incorrect configuration of the LPAR settings in the IBM Power Systems management interface can lead to this error.
  Resource Allocation Changes: Changes in resource allocation or the addition of new LPARs without adjusting the weights accordingly can trigger this error.
  
  Solution:
  
  Review LPAR Configuration: Check the configuration of all LPARs on the IBM Power Systems. Ensure that the total weight does not exceed the maximum limit set by the system.
  Adjust Weights: If necessary, adjust the weights of the LPARs to ensure that the total weight is within the allowed limits. This may involve reducing the weight of some LPARs or redistributing resources.
  Consult Documentation: Refer to the IBM Power Systems documentation for guidelines on configuring LPAR weights and understanding the limits specific to your hardware.
  Monitor Resource Usage: Use monitoring tools to keep track of resource usage and LPAR performance. This can help in making informed decisions about weight adjustments.
  Contact Support: If the issue persists or if you are unsure about making changes, consider reaching out to IBM support or your SAP Basis team for assistance.
  
  Related Information:
  
  IBM PowerVM: Familiarize yourself with IBM PowerVM, which is the virtualization technology used for managing LPARs on IBM Power Systems.
  SAP Basis Administration: Understanding SAP Basis administration can help in managing the SAP environment effectively, including resource allocation and performance tuning.
  Performance Tuning: Regular performance tuning and monitoring can help prevent such issues from arising in the future.
  
  By addressing the configuration and weight settings of your LPARs, you should be able to resolve the VIRT336 error and ensure optimal performance for your SAP system.
