Where did my ESX boot from?

Not many might have asked this question to themselves, but I have.
While working on testing multiple servers booted with ESX Visor, Thin installer, Stateless, Classic and some times, booted from SAN, it really matters a lot to know where is your system booted from.

The command to  your rescue is esxcfg-info -b


~ # esxcfg-info -b
49545178-05741713-8d31-0df7cceac42b

Another option that is useful while dealing with multiple flavors of ESX is
~ # esxcfg-info -e
boot type: visor-thin
