To configure an AFTD device on "StorageNodeA" with the name "OracleBackup" using the folder "D:\AFTD" to the pool "Default", the administrator can use the Data Domain CLI (Command Line Interface) to access the Data Domain system and create the AFTD device. Here are the steps:

• Log in to the Data Domain CLI by entering the following command:

ssh admin@StorageNodeA

• Once logged in, create a new AFTD device named "OracleBackup" by entering the following command:

ddboost afd create --name OracleBackup --pool Default --folder D:\AFTD

• Verify that the new AFTD device has been created by running the following command:

ddboost afd show --name OracleBackup

• To make sure that the Oracle backups only use the specific storage node, you can assign the AFTD device to the Oracle backup host by running the following command:

ddboost afd set --name OracleBackup --host OracleBackupHost

• Verify the configuration by running the following command:

ddboost afd show --name OracleBackup

• To make sure that the StorageNodeA is a dedicated storage node, you can configure the storage node to only allow the OracleBackup host to use the AFTD device by running the following command:

ddboost host access add --host OracleBackupHost --afd OracleBackup

Finally, the administrator should select the “Apply” button to save the configuration.
