NVP vProxy: FLR or Instant Access Restore Fails with "Unable to create datastore. Unable to complete Sysinfo operation"

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 restore 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\

nsrvproxy_flr: vProxy Log: YYYY-MM-DDTHH:mm:SS ERROR: [@(#) Build number: ##] Unable to create datastore 'EMC-FLR-VPROXY_NAME-########' using 'DATA_DOMAIN_ADDRESS:/data/col1/NETWORKER_MTREE/FLR--SESSION_ID': ServerFaultCode: An error occurred during host configuration. Operation failed, diagnostics report: Mount failed: Unable to complete Sysinfo operation. Please see the VMkernel log file for more details.: Unable to query remote mount point's attributes 

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 
----------------------   -----

Network File System (NFS) version 3 is the required default for VM FLR, and IA restores as per the NetWorker VMware Integration Guide.
 

1. Ensure that NFSv3 is enabled on the Data Domain system:
   1. Log in to the Data Domain web user interface: https://DD-ADDRESS/ddem
   2. Go to Protocols > NFS. Ensure, NFSv3 is enabled.
   3. Click Enable if NFSv3 shows as "currently not active."

Figure 2: Change NFSv3 to Enabled in PowerProtect DD System Manager. 

nfs enable version 3

2. Ensure that NFSv3 is set as the default-export-version:
   1. Log in to the Data Domain command line as sysadmin.
   2. Confirm that the default-export-version is set to "3" with the command:

nfs option show default-export-version

3. 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 
----------------------   -----

3. Perform VM restore.

The "Unable to complete Sysinfo operation" message can appear due to other issues, see:

• Blocked NFS ports: vProxy: FLR is failing for all clients with the error "Unable to create datastore"
• NAT Environment: NVP-vProxy: FLR "Mount failed: Unable to complete Sysinfo operation"
