illogical media management

Hello, I cannot found documents in the knowledge base regarding my problem.
I have an autoloader HP ultrium 448 with LTO 200/400GB that operate without
problem (it passed all the diagnostic test) and operate with my BE 10.0 correctly.
My BE 10.0 rev 5520 has the sp1, sp2 and all the hotfixes available installed.
My problem is about the rotation of the support: when my backup job need another media because the first became full, the job asks to me about inserting another media, but in the media set there are 7 media available. Obviusly the media aren't write protected and empty. In the BE option - Media management I've selected the partial media protection level and the "overwrite recyclable media... before overwriting scratch media" option and into the backup job properties i've selected the "append to media, overwrite if no appendable media is available" option. I think that's the right config, but all my backup jobs are still trying to write onto a scratch media.
I don't understand what's wrong.... When the job start take the first media of
his media set, but when it's full BE DOESN'T like all the other media in the media set.
(media are all new,empty and only labeled).
Sorry for my bad english,
i hope someone can understand (and solve) my problem.

Hi Gauri, thank you very much for your reply. I read the docs, but they doesn't solve my problem (unless there are something that i misunderstood...) My BE is configured with partial protection level, and the job is configured with "overwrite recyclable media contained in the targeted media set before overwriting scratch media" option. I have 4 media in my media set, with 1 week append period. when i start my backup job BE takes the 1st media from my media set, but when the media became full the job stops and ask me for overwritable media! I don't understand why it doesn't like the other 3 media!!!! If i move that media from the job media set to the scratch media set the job continue without problems....

Hello,

You could also create partitions, it provides more control over which media is used for backup jobs. Please refer to the following tech note to create the same:

Now i'm going to try to create a partition on my library. i'll tell to you the results very soon. But i'm still convinced that's something wrong in the behavior of my BE.

Sure! I tried a backup job with my partitioned library, but it returned the same error: when the first media became full it ask to me for a scratch media. it doesn't like the other media in his media set! I'm sure that the medias are all empty (just labelled), in the same media set and in the same partition.

Hello,

How many partitions did you create and how many tapes were there in each partition? You can put 2 tapes in one partition and then try the job. It should move to the 2nd tape.

As per the 2nd option in the default media settings, a Recyclable media is an
Allocated media that is part of a User Media set and has had its overwrite protection period expire. The media is available for overwrite operations or append operations (append operations are only possible if the append period still allows the media to be appended to). The media will be displayed in blue under the User Media set.

In your case it seems that the media is empty and not a media whose overwrite protection period has expired, thus the job could be going to scratch media.

Hope this information helps in clarifying the media behavior. If the problem persists, do write back with details.

I created 2 partitions and i put 2 tapes in the first partition, leaving the 2nd empty.
My job fills the first tape and stops, prompting for a scratch media....
You're saying that an empty media (just labeled) in my media set with 2 weeks of append period is not a recyclable media??? if this is true, why the job use the first tape? it has the same properties of append and overwrite periods!

Tomorrow i start my holidays, so i will not reply for 3 weeks.
Thank you all and see you in September.

Hello,


When a job is spanned on an another Tape, it will always ask for a new overwritable tape it cannot append on any other tape..



Thank You.

Sorry for my late, but i had some health problems... I understand that it will always ask for an overwritable tape, but a media into a media set with the protection period expired is not an overwritable media???

if you label a new tape, it is place in the scratch media set, and any job can grab it

If you then move the tape to a media set, it takes on ALL properties of the media set as of the time you move it.

if the OPP of the media set is 14 days, you will not be able to write to that tape for another 14 days.


Label the tapes, then place them in the appropriate partitions, and let BackupExec move them to the media set when it starts writing to them.

If this response answers your concern, please mark it as a "solution"

OK, thank you all.
I think that this kind of media management is a bit twisted, but it will not be a problem... thank you again!
