Re: [Networker] Client/Group not using full parallelism

Try starting the group with only that client.
(from CLI, it is easier from the backup server
without reconfiguring the group (savegrp -c client group))
Normally, client parallellism should be used.
But this depends also where the backup is sent to
(multiplexing of the tape device and max session
per device), how many available devices you have,
or pending media request
This depends also of storagenode max session
(32 or 64 depending of backup server edition)
and max server parallelism.
My feeling is first to give a try to increase
client priority to max priority within the
backup worklist and to monitor running sessions
(device availability, current parallelism).
You may also have to increase group paralelism
on top of client priority update.

Objet : [Networker] Client/Group not using full parallelism
I have one client in a group that does not seem to be following either
the client or the group parallelism. Server is 7.4.2 sp2 running on
Win2k3 server. Client is Win2k3 server with 7.2 client. The group
parallelism is set to 18, the client is set to 4, but only one session
at a time seems to run on this client after all other clients in the
group have completed. This client is a large file server with many small
files that always seems to finish last in the group. I want it to be
running at least 4 sessions whenever possible. It's currently streaming
only 1 session with 5 more partitions to go.. Which will take all day
due to the larger sizes of the partitions (35-50 GB each). Is there a
way I get it to reach the desired parallelism to increase the throughput
??
Regards,
Paul
