Error description

  • On rare occasions Tivoli Storage Manager server can crash when
    an NDMP backup or restore operation is initiated. This is the
    result of the server using a system call which is not thread
    safe.
    
    Tivoli Storage Manager Versions Affected:
    
    Version 5.x, 6.x and 7.x of the server.
    All linux and unix versions of the server can run into this
    problem.
    
    Customer/L2 Diagnostics (If Applicable)
    
    Call stack from core file may look similar to this:
     ndmpConnect (connection=)
     ndmpSession (ndmpcmdobj)
     spiSessInit (gHandle)
     ssInitStoreRemote (sessHandle)
     AfInitStoreRemote (sessP=)
     bfInitStoreRemote (moverName
     DoBackup (cmdP)
     AdmBackupNode (cmdP)
     AdmCommandLocal (cmdP)
     admCommand (cmdP)
     SmAdminCommandThread (smCmdP)
     StartThread (startInfoP)
     start_thread () from /lib64/libpthread.so.0
    
    Just before the crash, the actlog may show multiple backup node
    commands starting. It may look like this:
    
    ANR2017I Administrator ADMIN issued command: BACKUP NODE
    NDMPNODE1 (SESSION:1)
    ANR2017I Administrator ADMIN issued command: BACKUP NODE
    NDMPNODE2 (SESSION:2)
    ANR2017I Administrator ADMIN issued command: BACKUP NODE
    NDMPNODE3 (SESSION:3)
    ANR2017I Administrator ADMIN issued command: BACKUP NODE
    NDMPNODE4 (SESSION:4)
    ANR2017I Administrator ADMIN issued command: BACKUP NODE
    NDMPNODE5 (SESSION:5)
    ANR2017I Administrator ADMIN issued command: BACKUP NODE
    NDMPNODE6 (SESSION:6)
    
    Initial Impact:   MEDIUM

Local fix

  • Until fixing level is available, preventing concurrent NDMP
    operations will greatly reduce the chance of this crash from
    occurring.
