Cause

The NVE Domain Name System (DNS) is not properly configured to provide name resolution in the environment. As per the "Verify the DNS configuration" section in the Dell EMC NetWorker Virtual Edition Deployment Guide:

Before you deploy the NVE, ensure that the DNS server is configured correctly for the hostname and IP address of the vCenter server and the NVE appliance. Incorrect name resolution results in runtime errors and configuration issues.

Resolution

1. Connect to the NVE over SSH as admin.

NOTE: If the NVE is not accessible over SSH, you can connect to it using vSphere web console, from vSphere you can log in directly as root.

2. Switch to the root account: sudo su -
3. Confirm which DNS servers (if any) are defined in the NVE's resolv.conf file: cat /etc/resolv.conf
4. Modify the /etc/sysconfig/network/config file to contain the correct DNS servers and search suffix,

a. Look for the line containing NETCONFIG_DNS_STATIC_SERVERS and add the DNS servers, for example: 
NETCONFIG_DNS_STATIC_SERVERS="192.168.9.100 10.10.10.2"

b. Look for the line containing NETCONFIG_DNS_STATIC_SEARCHLIST and add any search domains. This typically includes the NVE's domain name and any additional DNS server domains.

NETCONFIG_DNS_STATIC_SEARCHLIST="amer.lan"

5. Save the file and confirm that the changes were applied to the /etc/resolv.conf file: cat /etc/resolv.conf

NOTE: If changes were not applied, run: netconfig update -f

6. Confirm that you can ping and resolve the DNS server:

ping DNS_SERVER_IPADDRESS
nslookup DNS_SERVER_IPADDRESS

7. Once DNS is properly responding, return to the NVE installation user interface and retry the task.
