IT15271: FILESET SNAPSHOT BACKUP FAILS ON SOME FILES WITH 'FILE NOT FOUND' ERRORS.

IBM Spectrum Protectâ„¢ Client 7.1.6 Downloads and READMEs

APAR status

• Closed as program error.

Error description

• When IBM Spectrum Protect client performs a fileset snapshot
  files larger than 100 MB, and files referred to with a symbolic
  link can report the following messages in the dsmerror.log file:
  ANS1228E Sending of object 'object-nameobjectnameobject-name'
           failed.
  ANS4005E Error processing 'filespace namepath-namefile-name':
           file not found
  The message ANS4005E "file not found", is false because the file
  is identified during the initial dsmc client discovery and does
  exist on the filesystem.  The SERVICE trace of the dsmc command
  will first show the file is found as shown in the following
  example:
  fs : /fs/w.c/users/.snapshots/mmbackupSnap20160316-w.c.users
  hl : /file_path
  ll : /file.txt
  Later the client will parse the same file again with a false
  result:
  fs  : /fs/w.c/users/.snapshots/mmbackupSnap20160316-w.c.users
  hl  : /w.c/users/file_path
  ll  : /file.txt
  Initial Impact:
  Medium - rarely happens.
  .
  IBM Spectrum Protect Versions Affected:
  Client versions 7.1.3.0 and above.
  .
  Additional Keywords:
  GPFS mmbackup ANS1228E ANS4005E dsmc client Spectrum Protect

Local fix

• Instead of taking a fileset snapshot for backup, take a
  whole-file-system snapshot followed by a fileset backup.

Problem conclusion

• Customer makes backups of a GPFS filesystem with mmbackup to a
  TSM server. The filesystem has several filesets and customer
  create a separate snapshot per fileset and do an mmbackup of it.
  Before fixing the issue after backup for some files, the
  'dsmerror.log' shows ANS1228E and ANS4005E errors ('file not
  found').  With the fix the mmbackup finished successful now
  without  dsmerror.log entries.
