Do you see any diskless MDs in the web-admin under "Wizard | Media Directors", you can also try setting one up manually there. It's been a while for me, but I think you only need to specify the MAC address.
The only MD that is in the "Wizard > Media Directors" are the Core..
Yeah, well.. I can try setting it up manually.. I`ll give it a shot!
Damn. How do I find my MAC adress ?
One way is to boot your machine with a livecd, like kubuntu 7.10, 8.4 or any other live cd distribution.
From console do: ifconfig
It is possible that there is a sticker on your network card that tell you which mac addr it has.
If you have your macine connected to lmce internal network, then from your cores console do:
You get a list with IPs and their mac addr.
Hope it will help you to find out.
