Error description
When running more than one BACKUP STG process in parallel for the same source disk storage pool (e.g. for creating copies in different libraries or data centers), not all data will be copied to all target storage pools due to internal locks on objects. The final statistics of the BACKUP STG processes indicate successfully completed operation including all data copied but verifying the data stored in the primary disk storage pool and the copy storage pools using the Q OCC command will illustrate not all data was copied to each copy storage pool. Example: - Primary disk storage pool 1 has objects A, B and C - Two BACKUP STG processes are startet in parallel copying data to pools 2 and 3 - Objects A and C are locked by BACKUP STG copying to pool 2 - Object B is locked by BACKUP STG copying to pool 3 - BACKUP STG copying to pool 3 will silently skip A and C - BACKUP STG copying to pool 2 will silently skip B This exclusive lock behavior was introduced due to changes made for APAR IC61439. A subsequent run of the BACKUP STG process will copy the missing objects. Platforms and versions affected: Tivoli Storage Manager 5.5.4 and above, 6.1.3 and above, 6.2 and 6.3 Initial Impact: Medium Additional Keywords: tsm movement data copy pool dr disk simultaneous storage pool xlock shared lock zztsm63 zz62 zztsm62 zz61 zztsm61
Local fix
Run BACKUP STG processes for the same disk storage pool one at a time.
