What Can I Do When the Active or Standby HA Server Is Faulty and Cannot Be Automatically Recovered?

What Can I Do When the Active or Standby HA Server Is Faulty and Cannot Be Automatically Recovered?

Symptom

The active or standby HA server is faulty and cannot be automatically recovered.

Possible Causes

The hardware on the active or standby server is faulty.

Procedure

  1. Rectify the active server fault.
    1. Query the status of the standby server and wait until it is switched to the active server.

      For details about how to query the status, see Querying the Deployment Mode Status and Service Information.

    2. Query the HA configuration on the normal server.

      For details about the query operation, see Querying Deployment Mode Configuration Information.

    3. Install eReplication of the same version using the software package or a template.

      For details, see Installing the eReplication Server.

    4. Complete the HA configuration of the new server by performing 1.b.

      • If the IP address and NIC MAC address of the new server maintain the same, perform 1.e.
      • If the new server adopts a new IP address and NIC, perform 1.f.

    5. Configure the new server as the standby server and configure it to be the same as the original active server.

      For details, see Configuring a Deployment Mode.

    6. If the IP address of the new standby server' heartbeat link or file synchronization link changes, you need to reconfigure HA and DR services for the active server. Reconfiguring the DR services will interrupt services.

      For details, see Configuring a Deployment Mode.

    7. After configuration, restart the system and query the HA status to check whether HA is successfully configured.

      For details about how to query the status, see Querying the Deployment Mode Status and Service Information.

  2. Rectify the standby server fault.
    1. On the active server, query the HA configuration.

      For details about the query operation, see Querying Deployment Mode Configuration Information.

    2. Install eReplication of the same version using the software package or a template.

      For details, see Installing the eReplication Server.

    3. Complete the HA configuration of the new server by performing 2.b.

      • If the IP address and NIC MAC address of the new server maintain the same, perform 2.d.
      • If the new server adopts a new IP address and NIC, perform 2.e.

    4. Configure the new server as the standby server and configure it to be the same as the faulty server.

      For details, see Configuring a Deployment Mode.

    5. If the IP address of the new standby server' heartbeat link or file synchronization link changes, you need to reconfigure HA and DR services for the active server. Reconfiguring the DR services will interrupt services.

      For details, see Configuring a Deployment Mode.

    6. After configuration, restart the system and query the HA status to check whether HA is successfully configured.

      For details about how to query the status, see Querying the Deployment Mode Status and Service Information.
