To add a node to a cluster that is using authentication for SFDB tools, perform the following steps as the root user

1. Export authentication data from a node in the cluster that has already been authorized, by using the -o export_broker_config option of the sfae_auth_op command.

   Use the -f option to provide a file name in which the exported data is to be stored.

   # /opt/VRTS/bin/sfae_auth_op \
   -o export_broker_config -f exported-data

2. Copy the exported file to the new node by using any available copy mechanism such as scp or rcp.
3. Import the authentication data on the new node by using the -o import_broker_config option of the sfae_auth_op command.

   Use the -f option to provide the name of the file copied in Step 2.

   # /opt/VRTS/bin/sfae_auth_op \
    -o import_broker_config -f exported-data 
   Setting up AT
   Importing broker configuration
   Starting SFAE AT broker

4. Stop the vxdbd daemon on the new node.

   # /opt/VRTS/bin/sfae_config disable
   vxdbd has been disabled and the daemon has been stopped.

5. Enable authentication by setting the AUTHENTICATION key to yes in the /etc/vx/vxdbed/admin.properties configuration file.

   If /etc/vx/vxdbed/admin.properties does not exist, then use cp /opt/VRTSdbed/bin/admin.properties.example /etc/vx/vxdbed/admin.properties

6. Start the vxdbd daemon.

   # /opt/VRTS/bin/sfae_config enable
   vxdbd has been enabled and the daemon has been started.
   It will start automatically on reboot.
