Symptoms

When performing an FLR recovery of a vProxy backup through the NMC Recover Tab the proxy is unable to mount the selected backup image.

FLR mount failure

Check the vproxy_flr recovery log located in the following folder on the NetWorker server:  
  • Linux: /nsr/logs/adhoc/nsrvproxy_flr/jobid.log
  • Windows (default): C:\Program Files\EMC NetWorker\nsr\logs\adhoc\nsrvproxy_flr\jobid.log
There is an error posted about Management credentials not being configured:

Cause

During a File Level Restore (FLR), or Instant Access Restore, the vProxy appliance creates an NFS datastore on the Data Domain and the NFS datastore/disks are exported to VMware for fulfilling the data recovery. This requires management access on the Data Domain to create and export the required data. The Data Domain's management credentials are empty (or incorrect) on NetWorker:

Empty management credentials

Resolution

  1. Log in to the Data Domain web interface using the sysadmin credentials: https://DD_ADDRESS/ddem/login
NOTE: The purpose of this is to confirm that the correct sysadmin credentials are known and the credentials are not locked. If you can log in, proceed with the next steps. If you cannot log in, consult with the Data Domain manager to get the correct credentials or consult with Data Domain support for resetting access.
  1. Log in to the NetWorker Management Console (NMC) or NetWorker Web User Interface (NWUI) using an Administrative account. For example, the default Administrator account.

NetWorker Management Console (NMC):

    1. Go to Devices -> Data Domain Systems.
    2. Right click the Data Domain and select Properties.
    3. Enter the Management User (sysadmin) and Management Password:

Management credentials in NMC 

NetWorker Web User Interface (NWUI):

    1. Go to Devices and Media -> Data Domain Systems.
    2. Select the Data Domain, then click Edit.
    3. Enter the Management User (sysadmin) and Management Password:

Management credentials in NWUI 

NOTE: The Management Host and Management Port options are optional, if nothing is specified, the default values are used. The Data Domain uses itself as the Management Host. The Default Management port (3009) is used.
  1. Perform the FLR mount operation again.

Additional Information

If another account other than sysadmin is used, it must be an account with "admin" rights on the Data Domain: https://DD_ADDRESS/ddem/#/access
