Basic Lan-free question

hi, i'm new and have some questions on lan free storage agent:

1. with lan free can i still have active pool and copy pool before migrating to tape pool. i read ibm storage agent guide it seem only directly to tape.

2. If for example i have 3 client nodes, a b and c. node c i install storage agent together with ba client, node b and c only ba client, no storage agent. once i link them together how node a and b transfer backup data to node c? tcp/ip? Then from node c to device via san? Am i correct?

3. i cannot find any resources or diagrams online relates to tsm on how to zone san so that all fiber connected tsm sever, library and client can communicate, can anyone advice?

Thanks in advance
