You can perform the above step using Fail Over Cluster Manager Console as well.

2.????? Attach the ISO file to the cluster node using the OEM Lights-Out Management interface such as iLO (HPE), iDRAC (Dell), etc

3.????? While logged on to the node via iLO console, browse to the directory of CD\DVD where ISO file was mounted in step 2.

4.????? Run the command shown below to start the Setup which will Auto Upgrade the Operating System and log files are stored under C:\Temp\IPU in case the upgrade fail and one need to find the cause of it.

Get-ComputerInfo | Select OSDisplayVersion

8.????? Resume \ Un-Pause the cluster node and failback any resources that were drained before the upgrade.

Resume-ClusterNode -Name NodeName -Failback Immediate
