Symptoms
VMware VMs are protected with the NetWorker VMware Protection (NVP) vProxy appliance.VM Image Restore process succeeds; however File Level Restore (FLR) or Instant Access (IA) restore fails.The recovery returns the following error:
The FLR logs are found on the vProxy under:
/opt/emc/vproxy/runtime/logs/recycle/vflrd
If the recover session was saved from NMC, the logs are found on the NetWorker server under:
Linux: /nsr/logs/recover/Windows: C:\Program Files\EMC NetWorker\nsr\logs\recover\

The Data Domain has NFSv4 enabled:
Figure 1: Data Domain System Manager Shows NFSv4 Enabled
The Data Domain's default-export-version is set to "4":
DD command:
sysadmin@ddve# nfs option show default-export-version
Option Value
---------------------- -----
default-export-version 4
---------------------- -----
Cause
NFSv3 is the required default for VM FLR, and IA restores as per the NetWorker VMware Integration Guide.
Resolution
Ensure that NFSv3 is enabled on the Data Domain system:
Log in to the DDEM web user interface: https://DD-ADDRESS/ddemGo to Protocols > NFSClick Enable if NFSv3 shows as "currently not active."
Figure 2: Change NFSv3 to Enabled in Data Domain System Manager.
OrEnable NFSv3 from DD command line with command:
nfs enable version 3
Ensure that NFSv3 is set as the default-export-version:
Log in to Data Domain command line as sysadmin.Confirm that the default-export-version is set to "3" with command:
nfs option show default-export-version
If NFSv3 is set to "4," change it to "3"
nfs option set default-export-version 3
Example:
sysadmin@ddve# nfs option set default-export-version 3
NFS option 'default-export-version' set to '3'.
sysadmin@ddve# nfs option show default-export-version
Option Value
---------------------- -----
default-export-version 3
---------------------- -----
Perform VM restore.
