I experienced the same situation and even the other side of it.

Tape drives set to 5 target sessions, client set to 15 parallelism.
During backup, some time it only stream 4 sessions, there are times
that it streams 8 sessions which is more than the tape drives target
session.

According to the instructor during my Networker training days, target
session per drive is not hard set, the server parallelism is what really
controls the save streams, if you have multiple clients starting at the
same time, that can limit your savestream per drive.

Are the savesets or file systems individually entered in each clients
'Save sets' list or just 'All', if you use 'All', you only have 1
savestream for that client.

I have 4 SDLT 220 drives on a StorageTek L180, I am trying to load up
1
drive with 10-15 savesets.

I have a group with 4 clients in it each with 4-5 savesets.
Clients are each set at Parallelism of 4.
Server Parallelism is 48.
Each Tape drive is set at Parallelism of 20.

When I run the savegroup I only get 4 sessions per drive.

I have stopped and restarted all Networker processes just in case and
that has not made any difference.

Backup Server: Solaris (Sparc) 8 / Networker 6.1.4 Network Edition
Clients: Solaris (Sparc) 8 clients running Networker 6.1.3

Any idea as to what I'm missing here?

Thanks.
