Error description

  • The SUMMARY_EXTENDED table might have unexpected SUB_ENTITY and
    SCHEDULE_NAME associations when multiple schedules for VM
    backups are defined to start at the same time.
    The activity log and scheduler logs will report successful
    completion and correct statistics, only the SUMMARY_EXTENDED
    table is affected.
    VMware and Hyper-V scheduled backups are affected.
    This impacts all monitoring tools using this table.
    
    Example :
    
    Three schedules are defined to backup three different VM guests
    to all start at 13:25 :
    
    schedule  VM guest
    --------  --------
    sched1    dummy1
    sched2    dummy2
    sched3    dummy3
    
    Upon completion, the following might be seen :
    
    select START_TIME, ENTITY, SUB_ENTITY, SCHEDULE_NAME from
    summary_extended where upper(schedule_name) like 'SCHED%' order
    by start_time desc
    
    
       START_TIME: 2013-12-01 13:25:58.000000
           ENTITY: 6.4_VC1_DC1_POL_DM1
       SUB_ENTITY: dummy3
    SCHEDULE_NAME: SCHED3
    
       START_TIME: 2013-12-01 13:25:41.000000
           ENTITY: 6.4_VC1_DC1_POL_DM1
       SUB_ENTITY: dummy2
    SCHEDULE_NAME: SCHED1
    
       START_TIME: 2013-12-01 13:25:18.000000
           ENTITY: 6.4_VC1_DC1_POL_DM1
       SUB_ENTITY: dummy1
    SCHEDULE_NAME: SCHED1
    
    The unexpected output is :
    
       SUB_ENTITY: dummy2
    SCHEDULE_NAME: SCHED1
    
    while we should see :
    
       SUB_ENTITY: dummy2
    SCHEDULE_NAME: SCHED2
    
    Tivoli Storage Manager Versions Affected:
    Tivoli Storage Manager server 6.3 and 7.1 and later on all
    platforms
    
    Initial Impact: Medium
    Additional Keywords: tsm zz64 vmware schedule summary report
    monitor unexpected backup VM
    

Local fix

  • Avoid defining schedules to start at the exact same time.
