Step 3: Updating Nodes of Windows Server HCI, Azure Stack HCI, and Failover clusters
20 Update firmware, BIOS, and drivers using Cluster-Aware Updating (CAU) in OpenManage Integration with
Microsoft Windows Admin Center (OMIMSWAC)
Figure 17: CAU update status for Windows Server HCI
Status column indicates the current state of the node that is Downloading/Successful/Failed/Scheduled. To
improve security, disable the CredSSP after the update operation is complete.
Note: While the update is in progress on the Cluster aware update tab, it is recommended not to exit or
close the browser. If you close or exit the browser, node updates may fail, and the update status may not
be shown. You can check the status by using Microsoft Cluster Aware Updating tool. Cluster Aware
Updating tool coming as Microsoft Failover Clustering tool and feature’s. For more information, see
Cluster-
Aware Updating requirements and best practices in Microsoft document.
The update job continues in the background regardless of whether the UI session is alive or not. If the UI
session is alive, node level progress status is displayed. OMIMSWAC notifies once the update job is
finished. After the update compliance repot is generated, OMIMSWAC saves the information of the baseline
catalog used for each solution.
Note: The Update feature of OMIMSWAC is supported on host with Microsoft Windows Server 2012 R2
and later.
10. If you want to run update on scheduled cluster then warning message appears at top. You can still proceed
with ‘Re-run compliance’, but at any given time, only one CAU job can be scheduled per cluster. Any new
CAU job (Run now or Schedule later) will replace the existing scheduled job.
