Configuring Disaster Recovery Site Servers

Scenarios

Configure disaster recovery site servers before you perform reverse reprotection for the protected instances on the console.

NOTE:

This operation is only required in 24.6.0 and an earlier version. In 24.9.0 and later versions, the disaster recovery gateway can be automatically configured.

Procedure

1. Log in to a disaster recovery site server.
2. Run the require script to configure the gateway.
   • Linux server:

     sh /opt/cloud/sdrs/register_gateway.sh

   • Windows server:

     Go to the C:\cloud\sdrs directory and double-click register_gateway.bat to run the script.

     Figure 1 Windows configuration script
     

3. Configure the script parameters.
   1. Cross-AZ scenario:
      Figure 2 Example configuration in Linux
      
      Figure 3 Example configuration in Windows
      
      Table 1 describes the variables in the command.

4. Configure the gateway for the proxy client on the disaster recovery site server:
   1. Linux disaster recovery server:

      su - service -c "/opt/cloud/sdrs/hostagent/bin/agent_config.sh --drm-ip=127.0.0.1 --ha-ip=127.0.0.1"

   2. Windows disaster recovery server:

      Open the cmd window and run the following command:

      C:\cloud\sdrs\hostagent\bin\agent_config.bat --drm-ip=127.0.0.1 --ha-ip=127.0.0.1
