I'm on the process of replacing a couple of old hard drives on my ESXi Server, but I don't know where the OS is Installed.
esxcfg-info -e
Run the following command.
esxcli system boot device get
Output:
Boot Filesystem UUID: 7f1ee37c-7b1bb9f9-574b-eca50bbdb3c2
Boot NIC:
Stateless Boot NIC:
The next question is how to connect that UUID to a Physical Drive.
Run:
esxcli storage filesystem list
Output
