Subscription Status Unknown

Issue

• The JetStream DR UI may indicate the warning “Subscription status unknown. Please check the management server’s external connectivity.”

• On the Configurations screen the Subscription ID is reported with a yellow icon.

  • Mousing over the icon indicates the status “Unknown”

Troubleshooting

1. Validate the connection from the MSA to the MMS server (40.112.243.46).

   • The following error may be reported if the connection fails:

[root@fs087-msa ~]# curl -v https://40.112.243.46:443

About to connect() to 40.112.243.46 port 443 (#0)
Trying 40.112.243.46... Connection refused
couldn't connect to host
Closing connection #0
curl: (7) couldn't connect to host

2. From the MSA, navigate to /var/lib/vme2/logs/ > jss.log and review the file.

   • If there is a communication between the MSA and MMS servers an MMS connection timeout error may be reported:
     2023-12-08 14:44:18,912 ERROR [Thread-8] (ReplicationSiteHelper.java:490) MMS status check failed.
at com.jetstream.jss.task.systemtask.MmsCommunicationTask.updateStatus(MmsCommunicationTask.java:152)
     

3. Check if a firewall is blocking the MMS server (jsdr-mms.azurewebsites.net/40.112.243.46) on port 443.

Resolution

• Open port 443 on the MMS server and verify connectivity to it from the MSA using the curl command: curl -v https://jsdr-mms.azurewebsites.net:443

• If the connection appears valid, wait a period of time to see if the warning goes away automatically.

• If the warning persists, restart the vme2 service on the MSA using the command: #service vme2 restart

  • The Postgresql and Tomcat8 services used by JetStream DR software will be stopped and then restarted.

  • The Postgresql service is the MSA DB service and the Tomcat8 service is a webserver service.

• Verify that status of the MSA services using the command: #service vme2 status. Pgsql and Tomcat8 services should both appear running.
