Hi All, 

We have a 3+3+1 vSAN Stretched Cluster, so 2 data sites each with 3 Hosts and a witness site. 

Only vSphere Standard in place, so vSphere HA Enabled. However no DRS as no licence for this. 

We want to simulate a data site failure, what would be the best way to do this so we can effectively complete a 'Test DR Site Failover'?

Would it be to login to the hosts iLO and simply power off the HPE Hosts? Or is there a built in script to initiate the vSphere HA workflow so it would gracefully shutdown the VMs in the data site, then power them on in the remaining data site?

Thanks,
