IC98469: UNEXPECTED SUB_ENTITY AND SCHEDULE_NAME ASSOCIATION IN SUMMARY_EXTENDED TABLE FOR VM BACKUPS

IBM Tivoli Storage Manager V6.3 Fix Pack 5 (6.3.5.000) Server Downloads

APAR status

• Closed as fixed if next.

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
