Error description

  • Incremental backup hangs when saving large disk managed by
    Windows HSM client.
    This happens because some migrated files need to be retrieved
    during the backup but there is a synchronization problem in the
    HSM plugin and that leads to a deadlock.
    
    Affected Products:
    Tivoli Storage Manager HSM for Windows version: 6.4.0.0,
    6.3.0.0 - 6.3.0.1 (inclusive), 6.1.0.0 - 6.1.5.1 (inclusive),
    the corresponding IBM Tivoli Storage Manager for Windows
    Backup-Archive Client versions are 6.1, 6.2 and 6.3.
    
    Customer/L2 Diagnostics :
    
    In actlog the session timeout :
       ANR0481W Session xxxx for node NODENAME (WinNT)
            terminated - client did not respond within 6000 seconds.
    
    In one of the HSM client  logs ( dsmc.log, dsmagent.log
    dsmcsvc.log )  , the following message may be seen
    
    DSMC (4188:26D0) connectToFileSpace

     E: INTERNAL: Not in critical setion: '0x0300005e (E:
