Possible Causes

The possible cause of this alarm is that the component status does not meet the requirements before the restoration task is executed or an error occurs in a step during the restoration task. The error depends on the task details. You can obtain logs and task details to handle the alarm.

Procedure

Checking the component status

  1. Log in to MRS Manager and choose Services. On the page that is displayed, check whether the running status of the components meets the requirements. (OMS and DBService must be in the normal status, and other components must be stopped.)

    • If yes, go to 7.
    • If no, go to 2.

  2. Restore the component status as required and start the recovery task again.
  3. Log in to MRS Manager and choose Alarms. In the alarm list, click the row containing the alarm and obtain the task name from the Location area.
  4. Choose System > Recovery Management. Search for the restoration task based on the task name and view the task details.
  5. Start the restoration task and check whether the task is executed.

    • If yes, go to 6.
    • If no, go to 7.

  6. After 2 minutes, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 7.

Collecting fault information

  1. On MRS Manager, choose System > Export Log.
  2. Contact the O&M engineers and send the collected logs.

Alarm Clearing

This alarm is automatically cleared after the fault is rectified.
