IT36288: 'ANS1017E SESSION REJECTED: TCP/IP CONNECTION FAILURE' WITH AUTOMATIC CLIENT FAILOVER ENABLED AND NO SPACE AVAILABLE ON DISK

APAR status

• Closed as program error.

Error description

• When having automatic client failover enabled, the IBM Spectrum
  Protect Backup-Archive Client tries to edit and save the
  dsm.opt file without checking the free space condition on the
  disk.
  If no space is being left on the device, the IBM Spectrum
  Protect Backup-Archive Client cannot save changes in dsm.opt,
  leading finally to an empty dsm.opt file.
  
  
  The Backup-Archive
  Client detects the no space left condition as seen
  here:
  
  ANS0361I DIAG: WriteCtrlRec(): fwrite: errno 28: "No
  space left on device"
  
  but does not prevent dsm.opt from
  editing with the automatic replication information.
  
  Due to the
  empty dsm.opt file and the missing connection information, the
  Backup-Archive Client cannot connect to the Spectrum Protect
  Server anymore (ANS1017E) and the dsm.opt will need to be
  recreated.
  

Local fix

• Ensure the location being used to store the opt file has
  sufficient free disk space and is not full or likely to be
  filled.

Problem conclusion

• Now before adding info about primary or secondary servers we
  create a temporary file of dsm.opt/dsm.sys. If this info was
  added without issues then we delete this temporary file. In the
  case of failure we delete dsm.opt/dsm.sys corrupted and rename
  correctly the temporary file.
