Symptoms

License server hostname has changed

NetWorker Management Console (NMC)

On the NetWorker server, launch the NMC Administration window, right-click the server, and then select Properties from the list. In the Licensing tab of the Server Properties window, browse to and select the license file to populate the CLP license text field.

While validating license file from NMC the following error appears:
 

Checking CLP connection using '/nsr/lic/licspec.properties'.
Checking license properties file '/nsr/lic/licspec.properties'
Found 'license.path=/nsr/lic/_NETWV_3651067_06-Oct-2018.lic'

FAILED
 
The lmgrd service is running, but the error still appears "Cannot read data from license server system"

Cause

NetWorker Server was connected to the old license server.
The hostname of the license server has changed.
Port 27000 and 27001 was not opened.

Resolution

  1. Killed the lmgrd service
  2. Start lmgrd service and read the license file
[root@emc]# lmutil lmreread -c /opt/emc/licenses

lmreread successful
  1. Check connectivity between the License server and NetWorker server. nslookup and ping is working fine but when we check for port its failing on license server
[root@emclicenseserver]# curl -kv hostname:27001
* About to connect() to hostname port 27001 (#0)
* Trying 10.33.16.154... Connection refused
* couldn't connect to host
  1. Open ports 27000 and 27001 at OS level and open it
  2. Update the license server name as specified in license file in nsradmin as it has old license server name and user has changed the hostname
