IT42825: MICROSOFT SQL LOG BACKUP FAILS WITH EXCEPTION OF TYPE 'SQLLOGBACKUP.GENERICCIFSCONTROLLEREXCEPTION'

APAR status

• Closed as program error.

Error description

• Starting with version 10.1.11, IBM Spectrum Protect Plus allows
  to backup Microsoft SQL database logs using a SLA.
  That type of log backup is called the advanced log backup
  approach as compared to the common log approach that consist of
  the agent creating a schedule locally on the Microsoft SQL
  server to save the backups periodically.
  In an AlwaysOn Availability Group (AAG), if an error happens
  while checking the Log Sequence Number (LSN) on any of the nodes
  part of the group, the log backup using the advanced log backup
  approach can fail even if that check is successful on the active
  node.
  The following messages will be seen in the job log :
  SUMMARY,..,,CTGGA2398,Starting job for policy <SLAName>
                               (ID:<SLAID>). id -> <JobID>.
