Jeffrey,
Usually new blank tapes injected inside the LIB will go to Scratch pool ..then once drive pickup that media and write ..Daily,weekly or monthly backups and put those media to the corresponding Volume Pool , ..If in case if any media going to any volume pool after inventoring means we need to specify the which media ID should go to which volume pool from (Netbackup GUI>> Robot inventory >> Update Volume configuration >> Advanced option)...
In same case if any media from other Lib injected inside in another Lib....it dont have Catalog database...where it will go ?.....For this i saw in Advance option, that ....Media 5XXXX should go to Scratch, Media CXXXX should go to None pool , Media 4XXXX should go to Netbackup pool ..like this....Now i will be happy because in absence of me...onsite engineer injected that media..some other colligues do inventory ..i am sure it will go to Netbackup pool..instead of Scratch .when my shift start i will start the further import process..:
If i am wrong ....pls excuse and correct me
