Full Stack Cluster-Aware Updating for Azure Stack HCI clusters using the OpenManage Integration snap-in

Windows Admin Center with the Dell extension makes it easy to update an Azure Stack HCI cluster using the cluster aware update feature. The feature updates the operating system and Dell-qualified firmware and drivers. When an update is selected, all the updates are installed on the cluster nodes. A single reboot is required to install operating system, firmware, and driver updates per server.

Note: Full Stack Cluster-Aware Updating (CAU) is only available on Azure Stack HCI clusters built using the Azure Stack HCI operating system. For more information about CAU, see Cluster-Aware Updating Overview.

Note: Full Stack CAU is a licensed feature. Ensure that the OMIMSWAC license is installed before proceeding.

To perform both operating system updates and hardware upgrades on Azure Stack HCI cluster nodes, carry out the following steps:

In Windows Admin Center, select Updates from the Operations menu.
You must enable CredSSP and provide explicit credentials. When asked if CredSSP should be enabled, click Yes.

The Updates page is displayed.
For an operating system update, see Microsoft's Azure Stack HCI documentation.
On the Install updates page, review the operating system updates and select Next: Hardware updates.
If the Dell OpenManage Integration extension is not installed, click Install to accept the license terms and install the extension. If you have already installed the OpenManage Integration extension, click Get updates to move to the Hardware updates page.
On the Hardware updates page, review the prerequisites listed to ensure that all nodes are ready for hardware updates and then click Next: Update Source. Click Re-Run to run the prerequisites again.
You must meet all the prerequisites listed on the Prerequisites tab, otherwise you cannot proceed to the next step.
To generate a compliance report against the validated Azure Stack HCI catalog, follow these steps on the Update source page:
- Select one of these methods to download catalog files:
  - Select Online (HTTPs) - Update Catalog for Microsoft HCI Solutions to download the catalog automatically from dell.com. The online catalog option is selected by default. Online catalog support requires direct Internet connectivity from the Windows Admin Center gateway. The overall download time of a catalog depends on the network bandwidth and the number of components being updated.
    Note: Accessing the Internet using proxy settings is not supported.
  - Select Offline - Dell Repository Manager Catalog to use the DRM catalog configured in a CIFS location. OMIMSWAC with or without Internet access allows you to select Offline - Dell Repository Manager Catalog to generate a compliance report. You can use this option when the Internet is not available. For more information, see Obtaining the firmware catalog for AX nodes or Ready Nodes using Dell Repository Manager.
  - To use the offline catalog, select DRM Settings to ensure that the CIFS share path is configured with the DRM catalog.
- To use the Dell System Update (DSU) and Inventory Collector (IC) tools, select Advance setting and then do the following:
  - Select Manually configure DSU and IC and then select Settings to manually download and configure DSU and IC tools in a shared location. Dell Technologies recommends using this option when OMIMSWAC is not connected to the Internet. DSU and IC settings that are configured using Update Tool settings in the OpenManage Integration extension are also available under Advanced settings in the OpenManage Integration snap-in.
  OMIMSWAC downloads the catalog, collects the DSU and IC tools that are configured in the Settings tab, and generates a compliance report. If DSU and IC tools are not configured in the Settings tab, then OMIMSWAC downloads them from https://downloads.dell.com to generate the compliance report.
On the Compliance report tab, view the compliance report. When finished, click Next: Summary.

The 'upgradable' components that are 'non-compliant' are selected by default for updating. You can clear the check box for the selected components or select the 'non-compliant,' 'downgradable' components. However, if you want to change any of the default selections, ensure that the dependencies between the corresponding component firmware and drivers are met.
On the Summary tab, review the components to be updated and then click Next: Download updates. The download task continues in the background whether the UI session is live or not. If the UI session is live, the node level progress status is displayed. OMIMSWAC creates a notification when the download task is finished.

Note: While the download is in progress, it is recommended that you do not exit or close the browser. If you do, the download update operation may fail.
If the download operation fails, check the log files stored at the following paths for troubleshooting purposes:
- Gateway system—<Windows Directory>\ServiceProfiles\NetworkService\AppData\Local\Temp\generated\logs
- Windows 10 gateway system—<Windows installed drive>\Users\<user_name>\AppData\Local\Temp\generated\logs
- After the cluster update is over, DSU logs for individual nodes can be found in the <Windows Directory>\Temp\OMIMSWAC folder on the respective nodes.
To run the compliance report again, click Re-run Compliance and repeat steps 4 to 7.
After the updates are downloaded, follow the instructions in the Windows Admin Center to install both operating system and hardware updates. If the UI session is live, the node level progress status is displayed. Windows Admin Center creates a notification once the update is completed.
