yes, each device has a target and max sessions value

our vtl devices all emulate a dlt7000 so I use this script to set these
settings to one:

#make dlt700 target sessions go to 1
nsradmin -i - <<EOF
show name;target sessions;max sessions;media type
print type: nsr device;media type:dlt7000
update target sessions:1
update max sessions:1
EOF 


while our PTL devices have target sessions set to 25


BEWARE!  there is a design flaw in networker that causes the lowest
target sessions value to be active for devices which have a different
target session setting

I swear this makes no sense and I have asked for a RFE to fix it

The manifestation is that the other devices (in my case LTO3) in a
different jukebox inherit the low target session value for any storage
node that can see both PTL and VTL

So when you go to use the PTL, you end up with target sessions 1 which
really screws the pooch

so before I use PTL, I have to reset the VTL drives so target sessions
equal those of the PTL:

#make dlt700 target sessions go from 1 to 25
nsradmin -i - <<EOF
show name;target sessions;media type
print type: nsr device;media type:dlt7000;target sessions:1
update target sessions: 25
EOF

maybe this is fixed in 7.3.3 (I'm going there today from 7.3.2) -
there's a chance - right?

cheers

Subject: [Networker] paralellism

Hey Guys,

We're looking at possibly purchasing an inline dedup VTL.  But as you
would expect it dedups best if you can send one stream per virtual drive
to the VTL.  I can't figure out how to limit the parallelism to that
particular autochanger but allow it to our real library.  It would be
really nice if target sessions would limit to that number, but it
doesn't. The only thing I can think to do is possibly have one save
group the a save group parallelism = number of drives.  But that seems
really limiting to be able to only have one group.

Am I missing something that can be done to just turn off parallelism for
a particular drive/library?

Thanks!

Joel
