How to change the Service Console MAC address?

[mistraller]

Our network department wants MAC addresses to create DHCP reservations for all systems with a fixed IP.

We handed over all virtual MAC Addresses of all service consoles on our ESX 3.5 U4 machines. This works.

After reinstalling an ESX after a disk failure, our service console MAC has changed. I'm looking for a way to configure it to the MAC address of the former esx server installation.

Is it possible somehow?

Hi

Are you sure you did not put the Service console on one of the other nics ? I am pretty sure the mac address is the actual "hardware" mac.

Edit /etc/sysconfig/network-scripts/ifcfg-vswif0 and restart network.

Lars, Service Console uses virtual NIC with autogenerated MAC from VMware pool (00:50:56).

You can see this MAC in Service Console properties, or directly in the file I specified above.

Why not just change the MAC address in the DHCP reservation?

So much easier.

Sometimes ESX admin and DHCP admin are different people

Every change in network environment needs to be done by another department, with a change procedure, and usually takes 3 or 4 days for a non critical change.

By changing the mac address it's much quicker, no documentation has to be changed, and no other people are involved.
