Restoring mail items to exchange 2010 dag with load balancer fails.

When I attempt to restore the mail items the job fails.  I found the article http://www.symantec.com/docs/TECH144195 which suggests using the redirect restore to the ip address of one of the CAS nodes.  My questions are:

1. Do I use the ip of the dag server that is hosting the active database or the one hosting the copy?

2. If I select the check box for Microsoft Exchange Redirection, do I put the server in the box as \\xxx.xxx.xxx.xxx or can I just use \\servername?

Thanks,
