IT12436: SNAPDIFF BACKUP OF CMODE CONFIGURATION FAILS WITH ANS2831E.

IBM Spectrum Protect client 7.1.4.x interim fix downloads

APAR status

• Closed as program error.

Error description

• When performing a Snapdiff Backup of a CMODE Netapp
  appliance which is specifying the UNC name the backup
  will fail with ANS2831E
  .
  The following error is seen in the DSMERROR.LOG:
  ANS2831E Incremental by snapshot difference cannot be performed
  on 'volumename' as it is of type 'Unknown' and is not a
  NetApp/N-Series 'CIFS' volume.
  
  Customer/L2 Diagnostics:
  A Tivoli Storage Manager client trace with the following
  traceflags enabled Service, Snapshot, Snapshot_Detail will
  show the following errors:
  ntrc.cpp( 736): TransWin32RC(): Translated Win32 RC 2 (0x0000000
  2) from
  GetDevIoVolInfo(): from call to psGetDevIoHandle() for volume '\
  \.\volumename:'
  to TSM RC 104
  ntrc.cpp( 798): TransWin32RC(): SnapshotErrMode = 0; dwWin32RC =
   2
  psfsinfo.cpp(1630): fioStatFS():  GetLVAttrib(\\vsrex\rexeeg$) e
  rror = 104
  

Local fix

• Ensure that drive letter mapping is used with the backup is
  being ran:
  net use z: \\xxxx\xxxxx$
  Use inc z: -snapdiff (on the client command line to perform the
  backup)

Problem conclusion

• The code has been changed so that the client uses now Windows
  APIs WNet* to enumerate network resources or existing
  connections.
  For the old Windows API NetUseEnum() the new testflag called
  NETUSEENUM was added. The flag is specified in the client
  options file (dsm.opt) as follows:
  TESTFLAGS NETUSEENUM
  

Temporary fix

• An interim fix is currently targeted for version 7.1.4.1.
  The client can use Windows APIs WNet* to enumerate network
  resources or existing connections.
  For this purpose the new testflag called WNETENUM was added. The
  flag is specified in the client
  options file (dsm.opt) as follows:
  TESTFLAGS WNETENUM
  Note that until the interim fix is actually available, this
  information is subject to change at the discretion of IBM.
