It's possible, depends how often you've been upgrading, if nothing has ever been changed!<br />
<br />
However the Default was Power Off.<br />
<br />
Shutdown is not the same.

We are currently using vCenter 6 update 2 and see that our HA isolation reponce is set to Shutdown. But have read the default isolation response should be leave powered on. Our have been around for a while and has been through upgrade from 4.x and up. Is this old setting a carry over. We are using C.N.A / FC adapters with backend SAN

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
