Error description

  • 4.x mmbackup/mmapplypolicy can produce errors when
    running
    with Spectrum Protect 7.1.8 and above.
    
    Error Description:
    This customer runs GPFS GPFS 4.2.2-3 on Linux.
    Customer recently upgraded the TSM client from 7.1.4.1 to
    7.1.8.0. Since the TSM client upgrade, the GPFS mmbackup
    now fails  to run. It logs the following error :
    --------------------------------------------------------
    mmbackup: Backup of /gpfs/eichler1 begins at   Wed Oct 11

    The TSM client error log shows the following errors :
    
    ANS1579E GSKit function GSKKM_ImportKeys failed with 17:
    GSKKM_ERR_DATABASE_INVALID_FILE_TYPE
    ANS9020E A session could not be established with a TSM
    server or  client agent.  The return code is -1.
    ANS5283E The operation was unsuccessful.
    

Local fix

  • 1) Make a copy of the /usr/lpp/mmfs/bin/mmbackup file
    2) Edit the /usr/lpp/mmfs/bin/mmbackup file and change :
    
    archiveProgram=${backupProgram}
    
    to :
    
    archiveProgram="LD_LIBRARY_PATH='' ${backupProgram}"
    
    3) Make a copy of the /usr/lpp/mmfs/bin/tsbackup33 file.
    4) Edit the /usr/lpp/mmfs/bin/tsbackup33 file and change
    :
    
    $backupProgram = "/usr/bin/dsmc";
    
    to :
    
    $backupProgram = "LD_LIBRARY_PATH=\"\" /usr/bin/dsmc";
    
    Following that, the mmbackup command worked fine.
    

Problem summary

  • GPFS and IBM Spectrum Protect use gskit library and both
    include gskit library in their packages. But the gskit from
    gpfs.gskt and gskit from TSM may not be compatible.
    Since all GPFS commands set the library path to
    /usr/lpp/mmfs/lib/gsk8, TSM commands may fail if invoked
    inside GPFS commands like mmbackup or mmimgbackup.
    

Problem conclusion

  • Reset library path before GPFS commands invoke TSM commands.
