NTP Sync

Periodically a user has the need to sync or resync one or more servers to the preferred NTP source. This might be required for various reasons including a network change, a new NTP server has been added, or a disaster recovery of an existing NTP server has taken place. Capabilities differ depending on the application. For example, The DSR Network OAM presents a broader scope of eligible servers than the DSR System OAM but the functionality remains the same.

Caution:

This operation should be planned. Critical processes are temporarily shutd down to complete the action. The user should understand the concepts of the High Availability (HA) subsystem related to Max Allowed HA Role. Reference HA (High Availability).

Note:

NTP Sync can only be performed on a server that currently reflects a Max Allowed HA Role of Standby, Spare, or Observer.

Use this procedure to perform an NTP Sync on one or more servers.

1. Click Status and Manage > HA.
2. Identify the target server(s) on which you want to perform the NTP Sync action. Confirm that all target servers reflect a Max Allowed HA Role of either Standby, Spare or Observer.
3. Click Status and Manage > Server.
4. Select one or more targets servers and click NTP Sync.
   A warning message appears:
   Are you sure you wish to force an NTP Sync on the following server(s)?
5. Click OK to continue.

The NTP sync action is invoked on the target server(s). A message is displayed at the top of the work area informing the user of the status of the operation.
