ONTAP MetroCluster

Synchronize the system time using NTP in a MetroCluster IP configuration

Each cluster needs its own Network Time Protocol (NTP) server to synchronize the time between the nodes and their clients.

About this task

  • You cannot modify the time zone settings for a failed node or the partner node after a takeover occurs.

  • Each cluster in the MetroCluster IP configuration should have its own separate NTP server or servers used by the nodes and IP switches at that MetroCluster site.

  • If you are using the MetroCluster Tiebreaker or ONTAP Mediator, it should also have its own separate NTP server.

  • This procedure shows how to configure the NTP after you have already set up the MetroCluster IP clusters. If you used System Manager to configure the clusters, you should already have configured the NTP servers as part of cluster setup. See Set up a MetroCluster IP site for details.

Depending on your ONTAP version, you can configure the NTP from the Cluster or Insights tab in the System Manager UI.

Cluster

In System Manager, you can configure the NTP from the Cluster tab using two different options, depending on your ONTAP version:

ONTAP 9.8 or later:

Use the following steps to synchronize the NTP from the Cluster tab in ONTAP 9.8 or later.

Steps

  1. Go to Cluster > Overview

  2. Then select the More option and select Edit.

  3. In the Edit Cluster Details window, select the +Add option below NTP Servers.

  4. Add the name, location, and specify the IP address of the time server.

  5. Then, select Save.

  6. Repeat the steps for any additional time servers.

ONTAP 9.11.1 or later:

Use the following steps to synchronize the NTP from the Insights window in the Cluster tab in ONTAP 9.11.1 or later.

Steps

  1. Go to Cluster > Overview

  2. Scroll down to the Insights window on the page, locate Too few NTP servers are configured, and then select Fix It.

  3. Specify the IP address of the time server, and then select Save.

  4. Repeat the previous step for any additional time servers.

Insights

In ONTAP 9.11.1 or later, you can also configure the NTP by using the Insights tab in System Manager:

Steps

  1. Go to the Insights tab in the System Manager UI.

  2. Scroll down to Too few NTP servers are configured and select Fix It.

  3. Specify the IP address of the time server, and then select Save.

  4. Repeat the previous step for any additional time servers.
