Parameters

Impact on the System

Because the configuration files on the standby Manager are not updated, some configurations will be lost after an active/standby switchover. Manager and some components may not run properly.

Possible Causes

The link between the active and standby Manager nodes is interrupted.

Procedure

1. Check whether the network between the active and standby Manager servers is normal.
   1. Go to the MRS cluster details page. In the alarm list on the alarm management tab page, click the row that contains the alarm. In the alarm details, view the address of the standby Manager server.
   2. Log in to the active management node. Run the following command to check whether the standby Manager is reachable:

      ping IP address of the standby Manager

      • If yes, go to 2.
      • If no, go to 1.c.
   3. Contact the O&M personnel to check whether the network is faulty.
      • If yes, go to 1.d.
      • If no, go to 2.
   4. Rectify the network fault and check whether the alarm is cleared from the alarm list.
      • If yes, no further action is required.
      • If no, go to 2.

2. Collect fault information.
   1. On MRS Manager, choose System > Export Log.
