        • This update need to be run on all compute nodes, broker nodes, head nodes, workstation nodes, unmanaged server nodes, and computers running the HPC Pack Client Utilities.

          Perform the following actions before installing the update
          1. Take all compute, workstation, and unmanaged server nodes offline and wait for all current jobs to drain
          2. Change the availability policy setting in the Windows Azure node template to manual
          3. Stop all existing Windows Azure compute nodes
          4. Close any HPC Cluster Manager and HPC Job Manager applications that are connected to the cluster head node
          5. Back up all HPC databases after all active operations on the cluster have stopped

          Applying the update
          To start the download, click the Download button next to the appropriate file (KB2867769-x64.exe for the 64-bit version, KB2867769-x86.exe for the 32-bit version) and then:
          1. Click Save to copy the download to your computer.
          2. Close any open HPC Cluster Manager or HPC Job Manager windows.
            Note: Any open HPC Cluster Manager or HPC Job Manager may unexpectedly quit or show an error message during the update process if left open. This does not affect installation of the update.
          3. Run the download on the headnode by using an administrator account, and reboot the headnode.
            Note: If you have HA head nodes, first update the active node, move the node to passive, and after failover occurs update the new active node. Do this for all head nodes in the cluster.
          4. Log on interactively, or use clusrun, to to deploy the fix to the compute, broker, workstation, and unmanaged server nodes.

          To use clusrun to deploy an HPC Pack 2008 R2 update on clusters that are running Service Pack 2, or higher:
          1. Copy the appropriate version of the update to a shared folder such as \\headnodename\HPCUpdates.
          2. Open an elevated command prompt window and type the appropriate clusrun command for the operating system of the patch, e.g.:
            clusrun /nodegroup:ComputeNodes \\headnodname\HPCUpdates\KB2867769-x64.exe -unattend -SystemReboot
            clusrun /nodegroup:BrokerNodes \\headnodname\HPCUpdates\KB2867769-x64.exe -unattend -SystemReboot
            Note: HPC Pack updates, other than Service Packs, are not automatically applied when you add a new node to the cluster or reimage an existing node. You must either manually apply or use clusrun to apply the update after adding or reimaging a node, or modify your node template to include a line to install the appropriate updates from a file share on your head node.
            Note: If the cluster administrator does not have administrative privileges on workstation nodes and unmanaged server nodes, the clusrun utility may not be able to apply the update. In these cases the update should be performed by the administrator of the workstation and unmanaged servers.
          3. To update workstation nodes and unmanaged server nodes you may need to reboot.

          To update computers that run HPC Pack Client Utilities apply the following actions:
          1. Stop any HPC client applications including HPC Job Manager and HPC Cluster Manager
          2. Run the update executable
          3. Reboot your client computer


          Uninstalling the update
          To uninstall the update
          1. Take all compute nodes, workstation nodes, and unmanaged server nodes offline and wait for all current jobs to drain
          2. Change the availability policy setting in the Windows Azure node template to manual
          3. Back up all HPC databases
          4. Stop existing Windows Azure compute nodes. You will need to redeploy Azure nodes after uninstalling the update. You do not need to delete them if you want to redeploy them in the future.
          5. You can uninstall the update in any order across all types of nodes.

          Some updates may apply to more than one piece of HPC Pack software. In order to uninstall those updates, remove them in the following order:
          1. Update for HPC Pack 2008 R2 Services for Excel 2010
          2. Update for HPC Pack 2008 R2 Client Components
          3. Update for HPC Pack 2008 R2 Server Components
          4. Update for HPC Pack 2008 R2 MS-MPI Redistributable Pack
          Note: If you don't follow this order, you might not be able to uninstall the updates because of dependencies across components

          Note: If you have HA head nodes, uninstall the updates on a passive head node, move the node to active, and then repeat uninstallation on the new passive head node. Do this for all head nodes in the cluster.
