In regard to: Re: [Networker] Question on target sessions?, Stuart Whitby...:
I'll do my Supporty bit now and say "Working as designed" :)
I would agree, *except* for the original scenario that George described.
That edge case sounds to me like a bug (or at least a deficiency that
could be rectified).

Hi,
Why is it that if the total number of save sets for a group exceeds the
value of the drive target sessions (in our case 4), and you only have
one writable tape, NetWorker will wait until the first 4 save sets have
completed before sending the next pending ones to tape?
NetWorker does ask for a second writable tape, and yes, if I had one
available, it would mount it, and then it would be writing 4 save sets
to drive 1 and 4 to drive 2, but I don't understand why it can't start
sending save sets that were previously pending to drive 1 as soon as one
of the running save sets completes. Instead, it seems to want to wait
until all 4 are complete, it then pauses for a minute and then continues
with the next 4, and so on. Is this normal behavior? It would be nice if
it could send stuff there as soon as something frees up and not wait.
We have 7.2.2 running on a Solaris test server, using a Linux storage
node. The tape library is on the storage node. It has 4 SDLT 600 drives,
each set to 4 target sessions, but I currently have only one writable
tape. The parallelism for the clients is set to default of 4, and the
server's parallelism is 20. I have a group of 8 clients and a total of
10 save sets for this test.
