Networker doesn't use all tape drives

Question

Hello, I've installed an Networker 7.2.1 environment based on Windows 2003 OS. The server is connected to an IBM Library with 3 LTO2 Drives. I've different groups running in the night, some of them use the same pool (Pool A) Every night I've got at least 4 free tapes on this pool but the software doesn't use the second tape until the first is full. So only one drive works and this stucks all the other groups, also on other pool. How Can I arrange the problem, any ideas Thank you Alberto

Of course, that what you configure. Decrease target sessions to 2 or 1 and you will use all 3 drives. Check manual to get an idea how this works and for best practice. This values should be set according to your environment.

each drive has a Target Session '5', and the same value is set for the parallelism on 'Set Up Server', if I increase this value I increase the number of the save set backed up simultaneously but on the same tape, the other two tapes are idle

Check your parallelism and target sessions.
