Cause

Name resolution issue. The wrong IP address mapped to the Data Domain in the hosts table of the NMC server.

 

Resolution

  1. On the NetWorker Management Console (NMC) server, confirm that you can resolve the Data Domain host and connect to port 161.
    nsrports -t DD_HOSTNAME -p 161

[root@lnx-nwserv]:~# nsrports -t ddve01.amer.lan -p 161
Forward lookup for ddve01.amer.lan
Query time:              0.001 sec
Canonical name (CNAME):  ddve01.amer.lan
Address (A):             192.168.9.106
Connect to port 161:     Succeeded (0.001 sec)

    If nsrports is not available you can use the following operating system commands: Linux: curl -v DD_HOSTNAME:161
    Windows (PowerShell): tnc DD_HOSTNAME -p 161

 

  1. Check the operating system hosts file on the NMC server and correct or remove any entries pointing to the IP address assigned to the Data Domain host.

  2. Restart the NMC service:
    Linux: systemctl restart gstd
    Windows:
    net stop gstd
    net start gstd
