Configuring Disaster Recovery Site Servers

Scenarios

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

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

Log in to a disaster recovery site server.
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

Configure the script parameters.

Cross-AZ scenario:

Table 1 describes the variables in the command.

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
