Catalogue backup failing

[C_Moisan]

Hello. I am testing 7.6.1.1 in my lab and I'm having a problem with my catalog backups. They are failing with a code 96 (unable to allocate new media for backup, storage unit has none available(96)). I compared with my production master and the policy is configured exactly the same. One thing that I can see being different is when the backup starts, the media server is the master itself. The thing is, the master is only active for disk and we want it to stay that way. The storage units are not using the master as media server so I don't understand that behavior... Anyone ever saw something like that?

Thanks!

What storage units do you have in the lab?

Which STU is selected in Catalog Backup policy?

If you have a disk STU in the lab, you need to select it explicitly in the policy.
Any Available setting (default) will not work for Basic Disk.
Disk STUs have a default setting of 'On Demand Only'. This means that STU must be explicitly selected.

I have 2 storage units and they are both tape STU. I have an STU group but I am using a specific STU in this case. I don't have a disk STU.

Check output of available_media on the lab master.

The robot in the STU needs media of the correct density (that matches STU density and tape drive density) in Catalog_Backup pool or in Scratch pool (if defined).

Here is the available_media output:

The other policies work flawlessly, by the way. It's just the catalog backup that doesn't work and it really seems to be related to the fact that it's using the master as a media server even though it shouldn't...

[Marianne]

You don't have any tapes in CatalogBackup pool and Scratch tapes are not in the robot.

[C_Moisan]

Ok, I spoke with my colleague and some of those tapes are from another incarnation of the lab... So I guess there is no scratch available to be put in the catalogue pool. We removed the old tapes and put some in the scratch pool and it worked. Thanks for letting me know about the available_media command!

Thanks!

HI

you have following tape available either move one tape in CatalogBackup pool or move them into scratch pool to pickup automatically
