This article applies to all JSDR software versions.<\/p>\n\n\n\n

Issue<\/h2>\n\n\n\n

Unable to access the JetStream DR UI from the vCenter. Various reasons described below may cause the problem.<\/p>\n\n\n\n

Symptom 1<\/h4>\n\n\n\n

The JetStream DR may become stuck in the “loading state” with no result and no error being reported.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Symptom 2<\/h4>\n\n\n\n

An error message may appear while the UI is being loaded:<\/p>\n\n\n\n

Error connecting to JetStream Management Server. Connection refused by Management Server. Make sure Management Server is running and services are accessible from outside.<\/kbd><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Symptom 3<\/h4>\n\n\n\n

An error message may appear when the UI is being accessed:<\/p>\n\n\n\n

Error connecting to JetStream Management Server. Make sure Management Server is running and vCenter Server is able to reach it by both its FQDN and IP address<\/kbd>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Troubleshooting<\/h2>\n\n\n\n
    \n
  1. Validate communication between the MSA and vCenter. This is mandatory for the seamless management functionality of JetStream DR. This can be validated using ping <\/strong><\/em>and curl -v<\/strong><\/em> commands.
    #curl -v https:\/\/<vCenter_IP or FQDN>:443<\/strong><\/kbd>

    \"\"
    \u00a0<\/li>\n\n\n\n
  2. Validate the MSA VM is up and running.
     <\/li>\n\n\n\n
  3. Ensure port 443 is enabled.

    \"\"
    \u00a0<\/li>\n\n\n\n
  4. From the MSA web console, check if the PostgreSQL <\/em>and Tomcat <\/em>services are up and running.
    #service vme2 status<\/strong><\/kbd>

    \"\"
    \u00a0<\/li>\n\n\n\n
  5. Re-establish the PostgreSQL and Tomcat8 services. PostgreSQL is the MSA DB service and Tomcat8 is a webserver service.\n
      \n
    • Manually start<\/strong> the services using the command: #service vme2 start<\/strong><\/kbd>.<\/li>\n\n\n\n
    • Completely restart <\/strong>both services using the command: #service vme2 restart<\/strong><\/kbd>.

      \"\"
      \u00a0<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • If it is noticed from the MSA web console that Tomcat8 service has not successfully started and continuously retries, manually restart the Tomcat8 service or consider rebooting the entire MSA VM.

      \"\"
      \u00a0<\/li>\n<\/ol>\n\n\n\n

      From JetStream DR software version 4.3 and beyond, it is possible to manually restart the Tomcat8 service. Use the following command to restart Tomcat8: #service msa-tomcat restart<\/strong><\/kbd>.<\/p>\n\n\n\n

      If you are unable to start the Tomcat8 service, contact JetStream support for additional assistance.<\/p>\n\n\n\n

      After making any changes to the MSA network, reboot the MSA VM for the changes to be reflected.<\/p>\n","protected":false},"excerpt":{"rendered":"
