Step 3: Updating Nodes of Windows Server HCI, Azure Stack HCI, and Failover clusters
18 Update firmware, BIOS, and drivers using Cluster-Aware Updating (CAU) in OpenManage Integration with
Microsoft Windows Admin Center (OMIMSWAC)
Figure 14: Schedule update
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.
Note: When components are selected and confirmed, if lockdown mode is enabled in iDRAC on the target
node, an error occurs and you cannot proceed to update. Disable the lockdown mode on the target node
that is being managed by OMIMSWAC before updating the target node. To disable iDRAC system lockdown
mode, see iDRAC documents.
