That depends on the setup on the Tape libray, i know when i worked on Adic, you 
have to configure masking etc and partition to properly prepare the tape 
library, secoundly your server should be zoned with FC drive from ADIC, if you 
provide zoning and masking information then we can see whats happening.If you 
see the drives on the server, you are only half done, as you need proper driver 
configuration and finally jbconfig has to be properly setup.If you connect 
drives directly to the server, this may be possible but more complex as you may 
need to set each drive in FC loop mode and then get tape library to work 
properly, my openion go with Tape library masked with server and properly zone 
the Tape library ports.Does Jbconfig find the tapes and the library on the 
server, then there may be a need to map lun zero properly to the server, some 
Tape library may not work properly if lun zero is not presented 
appropriatlly...going by my memory so doublecheck what i said , as i dont deal 
with backup any more just storage.I think you need end to end review of your 
enviroment to find the issue.ThanksFazil
