Hi Patrick,

Thanks for your thoughts.

Unfortunately I wish it were as simple as this :o(

I definately have only ONE Volume DataBase. This is stored on the host that 
controls the robot.

I believe the problem lies with the fact that NetBackup needs to maintain 
it's own distributed Media Database. Each server connected to drives 
maintains it's own Database. I can prove this by running an bpmedialist 
-summary, this lists each Slave's Media database.

Once a slave server writes to a tape, it exclusively owns it by making an 
entry for the Volume ID in it's Media database. Once owned, a volume cannot 
be used by any other host until returned to the Volume manager through 
expiry. I believe it is this behaviour that is this root cause of my 
problem.

Can any-one confirm/correct my understanding/observation or answer my
operational questions:-

   o Is this behaviour correct?
   o Is there a way of modifying it so that one SU can gain access to
     the other's volumes?


Regards,

George
