IBM Spectrum Protectâ„¢ Client 7.1.8 Downloads and READMEs

APAR status

• Closed as program error.

Error description

• IBM Spectrum Protect Client might crash after a "Backup VM
  -mode=full" or "Backup VM -mode=incremental".
  
  Following error messages are an indication of this APAR:
  
  04/28/2017 12:08:53 ANS0252E The sendObj ObjAttr.objInfo is too
  long.
  04/28/2017 12:08:53 ANS5250E An unexpected error was
  encountered.
     TSM function name : vmVddkBackupVM
     TSM function      : updateObject failed for hl \FULL, ll
  \VMNAME, fs \VMFULL-VMNAME.
     TSM return code   : 2101
     TSM file          : ..\..\common\vm\vmbackcommon.cpp (2438)
  
  The client crashes due to memory overwriting and/or access
  violation and might also crash before previous message is
  encountered. No error message will be seen in that case.
  The call stack depends on what memory was overwritten.
  The issue always happens after the backup finished, so backup
  data is not affected.
  
  The issue will not be seen when using Incremental Forever
  backups (IFFINCR & IFINCR).
  
  *Note: Periodic Full backups are not supported any more starting
  IBM Spectrum Protect for Virtual Environments - Data Protection
  for VMware 8.1
  
  IBM Spectrum Protect Versions Affected:
  IBM Spectrum Protect for Virtual Environments - Data Protection
  for VMware 7.1.6.5

Local fix

• Do not use Periodic Full VM backups but migrate to Incremental
  Forever backups.
