Is there a way to set off a VMware HA event in a cluster without causing a PSOD or killing the NIC?

The only 2 ways I'm aware of are unplugging the NIC or powering down the host.

I believe there is a way to set off isolation mode.  However, I'm still looking into trying to figure that one out.

To force a HA event a host must be isolated from the rest of the cluster on the vmkernel port where the service console resided, or in the case of multiple service consoles (managment network in ESXi) all must be unreachable for HA to kick in. As coolsport00 indicates this can happen if the network cable is unplugged or if the host is powered down suddenly (yank the power cables).

The only other way I know of to simulate this (and I have done this at my remote DR site) is to go into the physical switch and administratively set the port down.

One of the best HA articles I have read is http://www.yellow-bricks.com/vmware-high-availability-deepdiv/ - highly recommended.

Good Luck
