Hi,

Configuration :

Server A - library client / Data Manager
Server C - Library manager
Client is registered on Server A 
Storage agent is configured to connect to server A (devconfig)
Storage agent MUST be defined on BOTH server A and server C
And, last but not least, Paths are defined on Server C, library manager, which 
"own" the drives

Regards,

Pierre
