Error description

  • The IBM Spectrum Protect Plus maintenance job completes
    as partial. The reason why this happens is when the vSnap
      Replication runs, it runs against the latest backup snapshot
      that was successful.
    
      When the Vsnap Replication completes, the snapshot just used
      for the replication becomes Locked. In order for this snapshot
      to be released a new backup job must complete prior to the
      next vSnap Replication run time and then the vSnap Replication
      must run and complete.
    
      When the vSnap Replication job runs it will use the latest
      backup snapshot to complete the replication. Once the
      replication is completed, it will release the prior snapshot
      which was locked. Then that snapshot can be deleted by the
      maintenance job.

Local fix

  •   Either increase the backup retention to be greater then the
      replication frequency or increase replication frequency to be
      less then the backup retention.

Problem conclusion

  • IBM Spectrum Protect Plus has been updated to no longer end the
    maintenance job with a partial status when a snapshot is
    locked due to it being leveraged by the replication process.
    In addition, the messages that represent this condition has been
    improved.
    

Temporary fix

  • The failure of the maintenance job to delete a locked snapshot
    can be overcome by increasing the source retention so that the
    latest snapshot for a policy will not expire prior to the
    next replication occurring.
