High-availability clusters on SLES diagnostic information

This document lists the diagnostic information that helps Cloud Customer Care troubleshoot issues related to SUSE Linux Enterprise Server (SLES) high-availability (HA) clusters running SAP solutions on Google Cloud. Sharing these details when you create a support case helps Customer Care quickly isolate the root cause and reduce the overall resolution time.

Include the following details in your support case:

• A complete and detailed description of the problem or error, including the following:

  • The current application or system state.
  • The date and time when the error occurred.
  • If you're facing a performance issue with your SAP workload, then gather diagnostic information about SAP workload performance .

• If you're using Google Cloud's Agent for SAP , then generate and share the support bundle .

• If you aren't using Google Cloud's Agent for SAP , then collect information about the cluster, which includes the following:

  • From each node in the HA cluster, the TAR archive of the system report that you generate by running the SUSE supportconfig utility:

    supportconfig -l

  • The TAR archive of log files and node configurations that you generate by running the hb_report utility.

    Specify a start time ( from time ) that is approximately 1 hour before the issue occurred. Specify an end time ( to time ) that is at least an hour after the issue was resolved.

    Use the following command to run the hb_report utility, specifying the from time and to time on the '-f' and '-t' flags, respectively.

    hb_report -f " yyyy/mm/dd hh:mm 
    " -t " yyyy/mm/dd hh:mm 
    "
