DES-3128 Dell EMC NetWorker Specialist for Implementation Engineers Questions and Answers

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.

The rap log on a NetWorker server is used to audit recent resource changes, and if the file is empty, it is likely because the Monitor RAP attribute on the NetWorker server is disabled. This attribute must be enabled in order for the rap log to be updated. The other options are not related to the cause of the issue.

The client that initiated the directed recover is known as the source client. This client is responsible for sending the data to the destination client. The destination client is the one that will receive the data from the source client, and the administering client is the one that initiates the recover process. The NMC client is used for monitoring the recover process.

The error "Cannot contact a portmapper on port 7937" indicates that the portmapper service, which is required for the NetWorker Extended Client installation, is not running on the Linux host. The recommended action to resolve this issue is to install the lgtoserv-[version] rpm package and reinstall the Extended client. The other options are not related to this process.
