• Run Now—select to apply the updates immediately.

• Select a date and time to schedule a firmware update in future.

5. Select any one of the following methods, and click Finish.

• Agent-free staged updates—updates that are applicable without a system restart are applied immediately, and the updates that

require a restart are applied when the system restarts. To check if all the updates are applied, refresh the inventory. The entire

update job fails, if the operation fails on even one device.

• Agent-free updates—updates are applied and the system restarts immediately.

NOTE: OMIMSSC supports only Agent-free updates for MX7000 Modular Systems.

NOTE: Cluster-Aware Updating (CAU)—automates the update process by using Windows CAU feature on cluster

update groups to maintain server's availability. Updates are passed to cluster update coordinator that is present on

the same system where the SCVMM server is installed. The update process is automated to maintain server's

availability. The update job is submitted to Microsoft Cluster-Aware-Update (CAU) feature, irrespective of the

selection made from the Update Method drop-down menu. For more information, see Updates using CAU.

NOTE: After submitting a firmware update job to iDRAC, OMIMSSC interacts with iDRAC for the status of the job

and displays it in the Jobs and Logs page in the OMIMSSC Admin Portal. If there is no response from iDRAC about

the status of the job for a long time, and then the status of the job is marked as failed.

Updates using CAU

Updates on servers (that are part of cluster) happen through cluster update coordinator which is present on the same system where

SCVMM server is installed. The updates are not staged and are applied immediately. Using Cluster Aware Update (CAU), you can minimize

any disruption or server downtime enabling continuous availability of the workload. Hence, there is no impact to the service provided by

the cluster group. For more information about CAU, see Cluster-Aware Updating Overview section at technet.microsoft.com.

Before applying the updates on cluster update groups, verify the following:

• Ensure that the enrolled user has administrator privileges for updating clusters through CAU feature.

• Connectivity to selected update source.

• Availability of failover clusters.

• Check for cluster update readiness and ensure that there are no major errors and warnings in the Cluster Readiness report for applying

the CAU method. For more information about CAU, see Requirements and Best Practices for Cluster—aware Updating section at

Technet.microsoft.com.

• Ensure that Windows Server 2012 or Windows Server 2012 R2 or Windows 2016 or Windows 2019 operating system is installed on all

failover cluster nodes to support the CAU feature.

• Configuration of automatic updates is not enabled to automatically install updates on any failover cluster node.

• Enable firewall rule that enables remote shutdown on each node in the failover cluster.

• Ensure that the cluster group has minimum of two nodes.

NOTE:

• For information about applying the updates, see Upgrading and downgrading firmware versions using run update method .

• For information about Dell EMC Repository Manager to download firmware and driver updates, go to Firmware and Driver update

catalog for Dell EMC Solutions for Microsoft Azure Stack HCI page in dell.com\support and download the catalog file.
