BE 2012, HP MSL 6030 and Starwind Tape Redirector

Excuse my bad English!

I have MS 2003R2 cluster, two nodes, HP MSA 1000 with two FC SAN switches and HP MSL 6030. HP MSL 6030 use FC. Starwind Tape Redirector installed on the first node and configered.

I have MS 2008R2 cluster, two nodes, HP P2000 with iSCSI. BE 2012 cluster installed. I use MS iSCSI initiator for configure HP MSL 6030 and i see the  library in Device Manager. But BE 2012 don't add and configure the library. How to add the library?
