IJ53332: MMBACKUP MAY DISPLAY TOTAL BACKUP COUNT INCORRECTLY IF ONE OF THE HELPER NODES HAS SPECTRUM SCALE 5.1.8 OR OLDER VERSION INSTALL

APAR status

• Closed as program error.

Error description

• mmbackup command internally communicates with tsbuhelper process
  using a formatted string to get backup result and the format was
  changed in Spectrum Scale 5.1.9.0.

  to handle old format properly. As a result of it, the backup
  count from the node using old format is not correctly added up.
  

Local fix

  version is installed
