Two different questions...
Is the Quantum drive implemented in the tape device config file ?
It looks like it, as with the other branded Ultrium drives. see http://now.netapp.com/NOW/download/tools/tape_config/.
Will Networker invoke backups on the filer ?
I tried to do a deep dive on the issue the other week. It seems native 'dump' and 'restore' operations can be invoked with NDMP, but I did not find support
for invoking Snapmirror to tape from Networker. I got a bounce when I tried to email the NDMP support team with the question.
I do not have working experience with this configuration.
I hope this response has been helpful to you.
