How to find the shutdown-host's mac-address ?

[proxmoxajin]

A culster has 3 hosts , one of them was shutdown . No IPMI can be used , and I only can remote access the other 2 hosts.
Is there shutdown-host'mac address in somewhere or config-files?
Thanks!
Best Regards!

No. A mac address of remote host is not stored in any of the config files of the cluster.

The first three pairs of hexadecimal digits of a MAC determine the brand/vendor/manufacturer of the device. Maybe you can find out which ones those are? Then you only have to guess/try the last three pairs of hexadecimal digits, which are only 16,7 million different combinations, if you want to try to wake-up your unreachable system.
