Notes:

  1. (VSP 5000 series) The journal will be created as an open system journal if you do not specify the -timer_type option. If you specify -timer_type, the journal will be created for mainframe systems.
  2. Data Overflow Watch, Cache Mode, Timer Type, Path Blockade Watch, and MP Unit ID can only be specified all at once during the create journal operation using Device Manager - Storage Navigator. You can only specify them one-by-one with CCI and also you can modify the journal type options. For details, see the Command Control Interface User and Reference Guide.
