DR Replication – Network Communication Issue (SAP Production → DR Site)

  • 1.  DR Replication – Network Communication Issue (SAP Production → DR Site)

    Posted 11 hours ago

    HI,

    We are facing an issue with our SAP Production to DR replication. The delta log shipment, which runs weekly, is intermittently failing due to network communication drops between the on-prem environment and the PowerVS DR setup.

    Infrastructure Details:

    • DR environment is hosted on IBM PowerVS

    • Connectivity established through a GRE tunnel between:

      • On-prem Gateway Appliance

      • PowerVS environment

    • The Gateway Appliance maintains an IPsec tunnel with the on-prem Palo Alto firewall

    Problem Observed:

    We are experiencing intermittent network communication failures, causing delta log shipment interruptions.
    The issue appears to occur along the path:
    On-prem → IPsec Gateway → GRE Tunnel → PowerVS

    Requesting to check if anyone has faced a similar issue in a setup involving an on-prem gateway appliance (IPsec with Palo Alto) connected to IBM PowerVS through a GRE tunnel. Any shared experiences or guidance would be helpful.
