parallel processing

Hi,

we have a tape library with 4 drives.

Is it possible to limit the concurrent drives for a job to 1 specific drive ?

thanks !

Aren't you planning to share the library among different products/backup servers, by any chance? If so, then, it's not possible, unless you partition the library. Thanks!

Feature request for GFS media pools : Jobs pointed to this media pool can only use 1 drive

Can you describe the use case, since I don't seem to follow it - starting from Update 4 you can define number of parallel tasks a GFS media pool can handle. You can set there 1 to make it use only 1 drive at a time. However, there is no way to tie it to specific drive.

Thanks!

We backup multiple remote locations to one central site. There we create a tape job for each location, having one tape per location. All tape jobs start at the same time. A random tape job then is using multiple tapes instead of one tape (even when there is enough free space on the tapes), which is something we dont seem able to control. Basically we want make sure that per tape job, only one drive is being used. A second tape is fine, but only when the first tape is full.

Might be a misconfiguration or something, can you shed a light on your deployment? How media pool(s) configuration looks like: media set settings, overwrite protection period, number of parallel streams, etc.? Thanks!

Ouch..... the use of 2 tapes is correct. It happened to be that the free space indication of the 1st tape was in number exact the same as the free space on the 2nd tape. However GB and TB was the difference

No feature request needed, as it works as expected

Sometimes it just slips from your attention, no worries

Anyway, glad to hear your problem has been solved; thank for updating the topic!
