Source machines with no heartbeat [error 78174] RRS feed

  • Question

  • This article speaks directly to my issue - However, it lacks some details to actually be useful.

    https://github.com/MicrosoftDocs/azure-docs/blob/master/articles/site-recovery/vmware-azure-troubleshoot-replication.md


    This happens due to issues with Volume Shadow copy Service (VSS). To resolve:

    • Verify that the installed version of the Azure Site Recovery agent is at least 9.22.2. (WHERE? I am assuming on the ASR process server)

    • Verify that VSS Provider is installed as a service in Windows Services and also verify the Component Service MMC to check that Azure Site Recovery VSS Provider is listed. (MORE DETAILS, I am not exactly sure what/how this should be validated.)

    • If the VSS Provider is not installed, refer the installation failure troubleshooting article.

    • If VSS is disabled, (Are these installed on the Source Servers? I am guessing yes)

      • Verify that the startup type of the VSS Provider service is set to Automatic.
      • Restart the following services:
        • VSS service (I ASSUME, this is actually "Volume Shadow Copy")
        • Azure Site Recovery VSS Provider
        • VDS service (What is this service really called? Virtual Disk? should it be set to automatic?)
