What is the point of media sets...they don't work! 2

[ilpadrino]

Can someone help me understand what this software wants out of me? I want to duplicate disk-based jobs to tape using a 15-slot library. I can't create the duplicate job without designating a media set. So I have to put the tapes into a media set. But then after one tape, the job pauses (Queued) until I either move the tapes to scratch media or set overwrite protection to "None".

I had the media set settings as infinite overwrite protection and infinite append. All the tapes were allocated on the same day (after inv and erase) all there are over 10 with 100% capacity available.

Any help would be appreciated.

Dont move them to a media set. Move them to scratch media.
Set the target media set to overwrite protect for x amount of days after the jobs run. You dont have to put tapes in a media set at all. They should belong to scratch if they are new or belong to a media set and after x amount of time the overwrite protection period will expire and they become overwritable. Infinite overwrite ..once you write to them you will never be able to write to them again without moving them to scratch. Change the OP period on that media set

When creating the duplicate job it won't let me select scratch media for the media set, and won't let me submit the duplicate job without a media set.

Submit it to the media set you want it to goto. After the job run it will be assigned to the media set you specify. If the media is in scratch ANY job can use the media then it will be assigned to the media set and its properties.

Example: Let say you place 5 tapes in the autoloader. New tapes, erased, etc. They will by default belong to scratch media...or you could move them to scrath media. Create a media set called Tape_media_set. Set the overwrite protection to the media setup 5days and infinite allow append. WHen you run the dupe job point the job to Tape_media_set. Since the tapes are in scratch they are only available for jobs that have overwrite operations or append/overwrite. After the dupe job run..whatever tapes it use will be assiged to the Tape_media_set. They will be protected for 5 days. No other job can overwrite them. After 5 days the become expired. Any job targeting the tape_media_set will re-use these tapes.

Read these technotes and it should clear everything up.

Thank you. That help a lot. And it has worked exactly as you stated the last couple days. Now I just need to see if the timing on the overwrite protection will be correct and if the media can stay in the media set once it becomes recyclable. Otherwise I'll just erase it again.
