Fiber Channel Zoning

All -  I am looking for some detailed guidance / assistance.   I inherited a EMC Brocade Switch (SilkWorm 200E) which has only 4 devices connected to it.  The devices are as follows (2 connections for tape library, 1 connection for HBA of backup server and 1 connection to my Celerra).   Basically there is NO configuration on the device and as a resutl I have some issues with NDMP backup to tape concurrent with other backup.   I am running a job which does NDMP to tape and this is the only backup running over the swithc.   The rest of the communication is local network, and the media server running a duplicate job from disk to tape over Fiber.    I am looking for someone to help me or tell me exactly the steps to zone my switch properly to avoid conflicts and correct my problems.    Please private message me if you can assist me in this matter?  Or simply respond to me here.
