Error description

  • IBM Spectrum Protect Storage Agent will crash when e.g. 'show
    sdvars' or any other show command for the 'sd' component is
    executed.
    The following is an example from the stack while running the
    Storage Agent on an AIX system:
    
    pthread_kill(??, ??) at 0x900000000528f14
    _p_raise(??) at 0x900000000528764
    raise.raise(??) at 0x900000000039e68
    abort() at 0x900000000056864
    PsAbortServer(??) at 0x100016420
    pkAbort(??) at 0x10000cfe0
    pkAcquireMutexTracked(??, ??, ??) at 0x100007e58
    sdShowVars(??) at 0x100fb3d70
    AdmShow(??) at 0x100faf364
    AdmCommandLocal(??, ??, ??, ??, ??) at 0x100270ebc
    admCommand(??, ??, ??, ??, ??) at 0x10026e868
    IPRA.$ShowConfig(??) at 0x100fb26e8
    AdmShow(??) at 0x100fb21d4
    AdmCommandLocal(??, ??, ??, ??, ??) at 0x100270ebc
    admCommand(??, ??, ??, ??, ??) at 0x10026e868
    SmAdminCommandThread(??) at 0x1006c0ab0
    StartThread(0x0) at 0x10000e190
    
    Note: Running 'show config' will also cause the Storage Agent to
    crash because it invokes 'show sdxxxx' commands.
    Note 2: Running servermon.pl will also cause this issue.
    
    IBM Spectrum Protect and Tivoli Storage Manager Versions
    Affected:
    Storage Agent 7.1.3 and higher and 8.1.x on any supported
    platform.
    
    Initial Impact: Medium
    
    Additional Keywords: STA, lanfree, tivoli, storage, manager,
    tsm, container
    

Local fix

  • when running servermon.pl against a Storage Agent that is
    exposed to the subject APAR find the following 2 lines (about
    line 830) in the script:
             `$cmd  SHOW CONFIG > $configfile`;
             print "-- Wrote $configfile\n";
    
    and comment them out:
    #         `$cmd  SHOW CONFIG > $configfile`;
    #         print "-- Wrote $configfile\n";
