hmm… i’m not sure if baremetal systems w/o an OS will try to pull a DHCP address unless they attempt to PXE boot by default. though as Marek said, checking your DHCPD logs my help answer that question.
if you have managed switches, such as a cisco catalyst, you can log into the switch and run a command similar to ‘show mac address-table”. that should provide you with all MAC addresses that the switch sees per physical port. the command may change across different IOS versions on cisco switches and may be completely different for other switch manufacturers. if the switch in question has both OS loaded systems and BIOS only systems, you can compare the MAC’s provided by “show mac address-table” with the output of “arp –a” after running “ping –b 255.255.255.255” on a linux system on the same subnet.

It will say that there is no available lease and give you a mac address. With the terminal, just start a pxe boot ant you will see the mac it is using. ________________________________ From: [email protected] <[email protected]> To: [email protected] <[email protected]> Sent: Tue Aug 31 10:05:30 2010 Subject: How to discover the baremetal resources & install a VM image on thesame Hi all How do I discover the MAC address of machines that are available just with only BIOS installed (no Operating System present). And I need to find the mac address of such machines that are up with just BIOS. How do i do image installations on bare-metal ? Please Guide me. Thanks.
