Error description

  • The Tivoli Storage Manager server might crash when backing up
    device configuration information if the length of a device class
    definition exceeds the maximum length allowed for Tivoli Storage
    Manger administrative commands (1500 bytes).  This can happen,
    for example, when a device class is defined using abbreviations
    for some or all of the parameter names and the parameter names
    are then expanded to their full length by the BACKUP DEVCONFIG
    command.
    .
