Caution

  • Perform the start maintenance operation by using the [Start/End Maintenance] function before starting hot preventive maintenance. If the operation has not been performed, hot preventive maintenance cannot be started.

  • Hot preventive maintenance can be performed only on one component at a time.

  • This function can be performed when the component is in a normal state.

  • Be sure to use authorized maintenance parts for replacement. If components other than the authorized maintenance parts are used, operation is not guaranteed.

  • Not all maintenance parts can be replaced by using this function. Refer to the following tables for the availability of hot preventive maintenance for each part.
  • This function cannot be used under the following conditions:

    • The selected component is in the "Error" state

    • The selected component is not installed in the storage system (except drives)

    • The selected drive is being rebuilt

  • The Main CM is switched in the following conditions:

    • The Main CM is selected

    • The selected component is one of the following and the CM, on which the selected component is installed, is a Main CM

      • Memory

      • BUD

      • FAN Unit
