    ssi and mini_el are 64bit executables, whereas they should be
    32bit
    to allow initialization to complete.
    
    
    
    # file ssi
    ssi: ELF 64-bit MSB executable, IBM S/390, version 1 (SYSV), for
    GNU/Linux 2.6.4, dynamically linked (uses shared libs), not
    stripped
    
    # file mini_el
    mini_el: ELF 64-bit MSB executable, IBM S/390, version 1 (SYSV),
    for
    GNU/Linux 2.6.4, dynamically linked (uses shared libs), not
    stripped
    
    
    Tivoli Storage Manager Versions Affected:
    Tivoli Storage Manager Server: 7.1.x on s390x Linux platform
    
    
    
    Initial Impact: Medium
    
    Additional Keywords: SP TSM Spectrum Protect core crash abend
    acsls
    

Local fix

  • Use 32bit versions of "ssi" and "mini_el" from a 6.3.x.x server,
    or uninstall the 7.1.x device driver and install  6.3.x version.
