Users Guide

• Software and hardware requirements listed in the compatibility matrix of the Installation Guide are met.
• Ensure that the cluster service is up before running the update compliance. When the cluster service is down, an update compliance
report for a target node may not be generated.
• To manage a cluster, connect to the cluster using Manage as option and provide appropriate cluster administrator credentials. And
ensure that the user is part of the local user group of gateway administrators. For more information about selecting "Manage as", see
the "Get Started with Windows Admin Center" section in the Microsoft documentation.
• Ensure that inventory information for the target node has been retrieved.
• Ensure both physical, and virtual disks are in healthy state before triggering CAU.
• Ensure that iDRAC lockdown mode is disabled. To disable iDRAC system lockdown mode, see iDRAC documents.
• For 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
• Ensure that the target node is reachable using IP address, hostname, and Fully Qualified Domain Name (FQDN) of the target node.
NOTE: If the target node is not reachable, and the target node update is performed, the update status may show
failed. In this case, if you reboot the target node immediately after update and rerun the compliance, the target node
components status may show compliant, whereas the overall server update status may still show failed.
• Ensure that OMIMSWAC premium licenses are installed on all cluster nodes to use the CAU feature. To verify the licensing, you can
generate a compliance report to view the license installed on each node.
NOTE: It is recommended to validate the cluster before triggering CAU. For more information about validating a cluster,
see Microsoft documents Validate Hardware for a cluster.
NOTE: Updating a cluster where WAC is installed on a cluster node is not recommended. To support this scenario, install
the WAC on another system that is not part of the cluster and complete the update.
NOTE: While the compliance or update is in progress, it is not allowed to run any further compliance or update task for
the same cluster that includes the update requests from the MS WAC Update tools.
NOTE: The CAU feature is not supported for YX2X and YX3X models of Dell EMC PowerEdge servers.
Step 1: Generating compliance report—Target node
components in Failover Clusters and Azure Stack HCI
To generate a compliance report for target node components in Failover Clusters and Azure Stack HCI, select Update > Update Source,
and choose any of the available offline or online catalog options as follows:
Generating compliance report using online catalog
To use online catalog, OMIMSWAC must be connected to the Internet. OMIMSWAC with Internet access allows you to use the online
catalog option in the Update Source drop-down list to automatically download the catalog.
To view the compliance details, perform the following action:
1. Under Update > Update Source, choose any of the available online catalog options. The corresponding online catalog is selected by
default based on the cluster.
Available online catalogs vary depending on the cluster/target node you are connected to as follows:
• For PowerEdge servers and clusters containing PowerEdge servers: Dell EMC Enterprise Catalog which contains the validated
versions of components for PowerEdge servers.
• For MX servers: Dell EMC MX Solution Catalog which contains the validated versions of components for PowerEdge MX Modular.
• For Azure Stack HCI Cluster nodes: Dell EMC Azure Stack HCI Solution Catalog which contains the validated versions of
components for AX nodes and Storage Spaces Direct Ready Nodes.
For more information about available catalogs, see Appendix.
2. Select Next: Compliance details: to generate compliance report.
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, then OMIMSWAC downloads them from www.downloads.dell.com
to generate the compliance report.
