Change Network Settings After Deployment

Quantum recommends configuring the network settings during installation so that the StorNext Connect system and services are working together from the start. However, some optional settings can be configured at a later time; for example, as the environment scales and changes, a simple NAS-only configuration might later require DNS and NTP. The following sections provide tasks and considerations for the StorNext Connect system if you change settings after the system is operational.

If you add DNS, stats for previously configured clients may no longer be accurately reported. In that case, check that stats are still being reported. Contact Quantum support if they are not.

If using the NAS App, verify that hostnames displayed are correct.

Quantum strongly recommends using an NTP server. If NTP is not configured, and client stats are transmitted with a time that is later than the time on the StorNext Connect system, the stats are discarded and StorNext Connect does not report accurate monitoring stats.

Complete the following steps to add NTP after installation which ensures the StorNext Connect system reports accurate statistics going forward.

Verify that NTP is set up on the appliance (both nodes of a dual-node appliance) and on all clients in the workspace, and that they are configured to use the same NTP server.

If the NTP server is not set up, Quantum recommends the following steps to set up and start the NTP server time on the appliance server (MDC) node(s) and the clients in the workspace.

  1. Ensure that your local NTP server or public NTP server entry exists in the /etc/ntp.conf file of each host.

    Example

    server us.pool.ntp.org

  2. Ping the selected NTP server to make sure it is accessible.

    ping <NTP server IP address or hostname>

  3. Verify the NTP server entry exists in the /etc/ntp/step-tickers file. If not, add your server.

    Example

    us.pool.ntp.org

  4. Restart the ntpd service:

    service ntpd restart

  5. Verify the ntpd service is running:

    service ntpd status

  1. In StorNext Connect, in the Discover Components app, click Rediscover to update system information.
  2. In the Monitor Performance application in StorNext Connect, verify the Connector is passing the client's statistics to the StorNext Connect system:
    1. Click Client view.
    2. Select the client in the Client list, and click Update.
    3. Confirm that the application displays the client's statistics.
