Configuration of "Remote-updating mode" in Cluster-Aware Updating (Windows Server 2012r2) RRS feed

  • Question

  • Hi,

    I'm looking for exact steps (point 1-x) regarding Configuration of Remote-updating mode in Cluster-Aware Updating. There are extra steps needed since this one involves connecting from remote PC to a cluster with CAU. Those options are needed when setting up Self-updating mode:

    remote update for cau

    Microsoft covered Self-updating mode pretty well, but Remote-updating mode is just little here and little there:

    "Remote-updating mode For this mode, a remote computer, which is called an Update Coordinator, is configured with the CAU tools. The Update Coordinator is not a member of the cluster that is updated during the Updating Run. From the remote computer, the administrator triggers an on-demand Updating Run by using a default or custom Updating Run profile. Remote-updating mode is useful for monitoring real-time progress during the Updating Run, and for clusters that are running on Server Core installations."

    "You must install the Failover Clustering Tools as follows to support the different CAU updating modes:

    • To use CAU in self-updating mode, install the Failover Clustering Tools on each cluster node.

    • To enable remote-updating mode, install the Failover Clustering Tools on a computer that has network connectivity to the failover cluster."

    https://docs.microsoft.com/en-us/windows-server/failover-clustering/cluster-aware-updating

    "Remote-updating Enables you to start an Updating Run at any time from a computer running Windows or Windows Server. You can start an Updating run through the Cluster-Aware Updating window or by using the Invoke-CauRun PowerShell cmdlet. Remote-updating is the default updating mode for CAU. You can use Task Scheduler to run the Invoke-CauRun cmdlet on a desired schedule from a remote computer that is not one of the cluster nodes."

    https://docs.microsoft.com/en-us/windows-server/failover-clustering/cluster-aware-updating-faq

    This is some partial info. I'd need step by step configuration plus what  you exactly do on remote PC vs what you do on a cluster with CAU. Firewall, remote management etc...

    Thanks for your time!

  • Hi,

    Thanks for your question.

    Now prestage for CSU setup in GUI from a remote PC is same within the cluster nodes, we can refer to the following blog,

    https://www.altaro.com/hyper-v/cluster-aware-updating-hyper-v-basics/

    Furthermore, how we said that CAU has two modes, the remote-updating and the self-updating modes, and that it was important to know the difference. The first reason was that you couldn’t run the remote-updating from a cluster node. The distinction really comes into play when you start talking about Pre- and Post-Update scripts.

    When you perform a remote-updating (that’s when you go into the CAU GUI and select Apply cluster updates or use Invoke-CauRun in PowerShell), the script has to be visible from all nodes, and I think it also has to be accessible from the point you’re running the update from. Basically, I never got it to work right unless I had it on a share with read and execute permissions given to my administrative account, each computer node account, and the cluster node accounts (that includes the CAU account).

    For this details, we can refer to this blog,

    https://www.altaro.com/hyper-v/cluster-aware-updating-hyper-v-pre-post-scripts/

    Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.

    In addition, for the reqirements of CAU deployment, we can refer to the following section of CAU hardware and software requirements,

    https://docs.microsoft.com/en-us/windows-server/failover-clustering/cluster-aware-updating

    https://docs.microsoft.com/en-us/windows-server/failover-clustering/cluster-aware-updating-requirements

    Hope above information can help you.

    Highly appreciate your effort and time. If you have any question or concern, please feel free to let me know.

    Best regards,

    Daniel
