Dell OpenManage Integration with Microsoft Windows Admin Center Version 3.0 User’s Guide

Prepare nodes for Failover cluster expansion


  • Ensure that 'OMIWAC Premium License for PowerEdge' is installed on cluster nodes as well as the new node.
  • For new nodes with SAS-RAID_Driver, ensure the followings:
    • Set the SATA controller to RAID mode.
    • Set the NVMe PCIe SSDs to RAID mode.

      For more information about setting the RAID mode, see Appendix

Planning before preparing a node for cluster expansion:
  • Place the new node in a rack and cable it properly.
  • Ensure the same operating system is installed on the new node as on the existing cluster nodes.
  • Connect the node using the Windows Admin Center and configure the basic settings such as username, domain, and so on.
  • Ensure new nodes are in the same domain as of cluster nodes and they are accessible by the domain administrator.


To prepare nodes for cluster expansion:

  1. Connect to the cluster using Windows Admin Center and launch OpenManage Integration extension.
  2. Select View > Expand Cluster. Another menu with drop-down appears. Select Add Nodes. Alternatively, go to the Action menu, under EXPAND CLUSTER, select Add Nodes.
  3. To display list of nodes, under Select Nodes to Prepare, click Select Nodes. The extension fetches all nodes available on the Server Manager page in the Windows Admin Center and displays the list of nodes.
  4. Under Select compatible nodes, select any nodes that you want to add to the cluster. You can also search any node using the search box or click select all check box to select all nodes. Ensure that new nodes are not part of the cluster.
    NOTE: Total number of nodes supported in a cluster is 16. For example, for a cluster with existing 4 nodes, you can select up to 12 nodes for cluster expansion.
  5. After nodes are selected, click Check in Recommendations and then click View Details to see recommended and not-recommended nodes for cluster expansion. For more information about Recommendations check, see View Recommendations check.
  6. Click Check in License Availability to verify whether new nodes and cluster nodes have 'OMIWAC Premium License for PowerEdge' installed.
    Before moving for update compliance, ensure new nodes considered from recommendations check and cluster nodes have OMIWAC premium license installed.
  7. After you successfully complete the Recommendations and License Availability check, click Save. Under Select Nodes to Prepare, click Update Compliance to check for firmware, BIOS, and drivers compliance for new nodes and cluster nodes. Using 'Expand Cluster', you can update firmware, BIOS, drivers, and system management applications of new nodes only. To generate compliance report for both new nodes and cluster nodes:
    1. Select one of the methods to download catalog files.
      • Online Enterprise catalog to download the catalog automatically from for PowerEdge servers. Online catalog is selected by default.
      • Online - MX catalog contains the validated versions of components for PowerEdge MX Modular.
        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 number of components being updated.
        NOTE: Accessing to the Internet using proxy settings are not supported.
      • Offline catalog to use the DRM catalog configured in a CIFS location.

        OMIMSWAC with or without Internet access allows you to select the Offline - Dell Repository Manager Catalog to generate compliance report. You may use this option when the Internet is not available or to use a customized DRM catalog. When internet is not available, before using offline catalog ensure DSU and IS settings are configured on the Settings page.

        • To use offline catalog, select DRM Settings to ensure the CIFS share path is configured with the DRM catalog. To create a DRM catalog, see the Technical article.

      When finished, click Check Compliance.

    2. Compliance Results displays compliance summary of cluster nodes and new nodes. Click View Details to see the compliance report or Export to export the report in CSV format. For more information about compliance report, see View hardware compliance report.
      • If cluster nodes are non-compliant, ensure the cluster nodes are compliant before adding new nodes in the cluster. To update cluster nodes, exit the wizard and go to the Update tab for cluster update using cluster-aware updating method. And then use the "Add Nodes" feature to prepare nodes for cluster expansion.
      • If new nodes are non-compliant, click View Details in the Compliance Results to verify the non-compliant components and then click Finish to update the new nodes components and keep them ready for cluster expansion. Click Update in progress - View Details to see the update status.
      • If both cluster nodes and new nodes are compliant, click exit and follow Microsoft recommended steps to add nodes to the cluster.

Next steps

After both new nodes and cluster nodes are updated, navigate to the Windows Admin Center workflow to add new nodes to the existing cluster.
NOTE: Before adding a node to the cluster, ensure that you configure the host OS network to the new nodes same as the cluster nodes.
