IT11729: ANS5250E MESSAGE ON SNAPDIFF BACKUP FOR C-MODE NETAPP FILER

IBM Spectrum Protect client 7.1.4.x interim fix downloads

APAR status

• Closed as program error.

Error description

• A snapdiff backup for a volume on a Cluster mode Netapp filer
  might stop with the message :
  
  ANS5250E An unexpected error was encountered.
    TSM function name : baPerformSnapDiff
    TSM function      : Invalid CIFS share - not a NetApp share
  or full volume.
    TSM return code   : 115
    TSM file          : backsnap.cpp (5581)
  
  Mounting a c-mode volume to a junction point named /vol will
  cause the problem.
  This often happens when migrating 7-mode volumes to c-mode
  (/vol is the default builtin name space volumes are mounted
  under in c-mode)
  In such a scenario, the volume name used in the backup command
  is not a full volume.
  The volume is a full volume if it is mounted or mapped to the
  root of the volume.
  To check this, use the Netapp Filer GUI and check that the
  volume has a namespace corresponding to the volume name used in
  the backup command and that it is mapped to the root volume.

Problem conclusion

• The code has been changed so that the client will correctly
  process c-mode volumes with manually added /vol prefix to the
  junction-path.
  For this purpose the new testflag called SNAPDIFFCMODEVOLPREFIX
  was added. The flag is specified in the client options file
  (dsm.opt) as follows:
  TESTFLAGS SNAPDIFFCMODEVOLPREFIX
  

Temporary fix

• An interim fix is currently targeted for version 7.1.4.1.
  Note that until the interim fix is actually available, this
  information is subject to change at the discretion of IBM.
