I'd start with the xm reference page:
That breaks down your command parameters pretty well. I don't see the -2, but -L is to dump core live, without attempting to pause the domain. It should then have the domain name and optionally file name.
If you experience an error trying to use the command, please include that as well in your messages.
Note that xm has been supplanted by xl, but on Xen 4.1 you are probably still using xm.
