Cause

The admin role is required to mount Network File System (NFS) datastores. If the DD Boost User does not have the correct role to mount an NFS datastore on to the Data Domain, instant access fails. This can be confirmed by using the user change role command to verify the DD Boost User role: user show detailed <ddboost-user> Example and sample output:(For this example, the DD Boost User is ddboost-av) user show detailed ddboost-av User: ddboost-av Uid: 502 Role: user Last Login From: management-station1.customer.com Last Login Time: Mon Apr 11 13:08:04 2025 Status: enabled Password Last Changed: Dec 31, 2024 Disable Date: never Minimum Days Between Password Change: 0 Maximum Days Between Password Change: 99999 Warning Days Between Password Change: 7 Disable Days After Expire: never

Resolution

Change the DD Boost User role to admin: 1. Log in to the Data Domain with an account that has admin privileges (for example sysadmin). 2. If the DD Boost User is unknown, run the following command: ddboost user show Example output: DD Boost user Using Token Access ------------- ------------------ ddboost-av - ------------- ------------------ 3. Use the user change role command to verify the DD Boost User role: user show detailed <ddboost-user> Example and sample output:(For this example, the DD Boost User is ddboost-av) user show detailed ddboost-av User: ddboost-av Uid: 502 Role: user Last Login From: management-station1.customer.com Last Login Time: Mon Apr 11 13:08:04 2025 Status: enabled Password Last Changed: Dec 31, 2024 Disable Date: never Minimum Days Between Password Change: 0 Maximum Days Between Password Change: 99999 Warning Days Between Password Change: 7 Disable Days After Expire: never If the role is already admin, stop using the article. 4. Use the user change role command to change the DD Boost User role to admin: user change role <ddboost-user> <role> Example and sample output:(For this example, the DD Boost User is ddboost-av) user change role ddboost-av admin Role changed for user "ddboost-av" 5.
