Due to a planned power outage, an administrator decides to shut down the vSAN cluster...

To shut down the vSAN cluster using the Shutdown Cluster Wizard, the administrator needs to turn off High Availability (HA) before starting the wizard. This is because HA monitors the cluster for host failures and attempts to restart the affected VMs on other hosts. If HA is not turned off, the cluster might register host shutdowns as failures and trigger unnecessary VM restarts, which can interfere with the graceful shutdown process. Therefore, the administrator should disable HA from the Configure tab of the cluster before using the Shutdown Cluster Wizard12 References: 1: Shut Down the vSAN Cluster Using the Shutdown Cluster Wizard 3 2: Manually Shut Down and Restart the vSAN Cluster 4
