detrmining mac address on a new 11.23 server

Bob Carback — Mon, 07 Aug 2006 15:03:46 GMT

I have a new Itanium server. I plan on building this server from a Golden Image archived on my ignite server. I need to place the mac address of the new server into the /etc/bootptab file. How can I determine the mac address of the new server?

lanscan will give you the mac address...

Shalom,

lanscan displays all MAC addies,

ifconfig lan0 (use the lan you want) provides this information for a specific interface.

I am unable to lanscan as there is no OS installed as of yet.

assuming that you are on the same lan/vlan with this new server. otherwise you will not be able to ignite it anyway.

If this is correct, from the ignite server, run

arp -a

command and with a little bit of luck, you can easily eliminate the server names and ip addresses you already know, leaving you the interface you are looking for. formatting of the mac address is a little awakward as arp seems to disregard the trailing zeros in the macc address but nothing of a showstopper.

hope it helps.

You should be able to do it from the MP

use the following MP commands
IN (information)
LanAddress

:-)) It's most probably printed on the NIC so why don't you just take a look...

You might also get it from the switch it is connected to if you talk to your LAN admin.

It is likely not to get a way to know th MAC
without confirm the MAC on the NIC.

None of these worked. I found the answer --

on bootup, interrupt the boot process and from the EFI boot manager menu choose 'System Configuration', then 'Advanced System Information', then 'Display All Information'. Page through until LAN information including MAC is displayed.

Hi Bob,

in order to boot an Integrity system from an ignite server, you have to perform the lanboot command in EFI:

Shell> lanboot select
01 Acpi(000222F0,0)/Pci(1|0)/Mac(00306E0E5268)

The command will show you all bootable NICs including their MAC addresses.
