Mutilistream Job does not start after resuming from Suspend state

Dear all,

Master/media NBU : 6.5.6 | Win 2003 EEx64

Policy with Multistream enabled, doesnt start after i resume from suspend. Rather, the parent job stays in Queue and childjobs show in suspend state. MPX level= 32 is set to all jobs and still its not able to write along with other few backup jobs (not multistreamed) are running.

Scenario:

1) We have 4 drive mapped to the media server, i downed 3 drives and started two policies

             Policy1 : MPX 32 | not multistreamed | 3 jobs (3 clients)

             Policy2:  MPX 32 | multistreamed | 5 jobs (1 client)

2) Alll 8 jobs started writing on the drive D1 (rest 3 drives are in down state)

3) Suspended the Policy 2 parent job and resumed after a while. The job is unable get the drive.

             Parent : Queue & Child: Suspend state

4) When i UPed the other drive D2, then the parent job started writting on drive D1.

 

Its weired why the Parent job did not start after resuming, though there were only 3 job runnign on the drive and MPX is set to 32.

 

Any inputs or idea on this case?

    It indicates that Storage unit is unable to allocate drives for the job.

    I have attached the nbrbutil dump while the job was in queue

    then are they mounted with media inappropriate for the resumed jobs?

    I have a feeling you're going to say "No. The loaded tape(s) are in the correct pool, retention level etc etc" & the drives do allow multiplexing etc etc .... if that is the case I haven't a clue.

    The loaded tape in the drive are in correct pool, retention and drive is set to multiplexing, the resumed job only goes active on the drive with loaded tape, when a different drive is available.

    when a different drive is available."

    Huh? So it waits for something it doesn't need to become available before it uses something it does need that's always been available? Where's the logic there?

    Correct, Thats the problem... It waits for other drive to be available (with no jobs), but nevers uses it; rather it goes active on the drive in which it was writing earlier before suspend.

    i.e. jobs are not resuming until a second drive is made available & then the resumed job uses the other tape drive?

    Or is it that you just need to know how to resume a job? If the latter it should've really been a separate discussion, but....

    from the GUIs "Help":

    To resume a suspended or an incomplete job

     

     

    • 1. Open the Activity Monitor and select the Jobs tab.

     

     

    2. Select the suspended or the incomplete job you want to resume.
    3. Select Actions > Resume Job. All selected jobs are resumed.
     
    Note: Only the backups and the restores that contain checkpoints can be suspended.

    [[or right-click job(s) & select "Resume Job"]]

    MariusD,

    Are your jobs multistreamed and experiancing the same senerio as mentioned in my post?
