2700 Failed to synchronize cluster time to NTP server

User response

There are three main causes to examine:

• The cluster NTP network time server configuration is incorrect. Ensure that the configured IP address matches that of the NTP network time server.
• The NTP network time server is not operational. Check the status of the NTP network time server.
• The TCP/IP network is not configured correctly. Check the configuration of the routers, gateways and firewalls. Ensure that the cluster can access the NTP network time server and that the NTP protocol is permitted.

To fix the issue:

In the management GUI, go to Settings > System > Date and Time to verify that NTP is configured correctly.

1. Ensure that the IP address is correct.
2. Set the time zone to the geographical location of your system.
3. If the NTP server uses authentication, ensure that the type and parameters match the configuration of the server.

If the problem persists, check for problems outside of the system, for example:

1. Ensure that the NTP time server is functioning correctly.
2. Ensure that the IP network is configured to allow connections between the NTP server and all nodes in the system.

If NTP is no longer required, set the date, time and time zone manually. If you are located in the same time zone as the system, you can choose to use your browser settings to do this. Alternatively, you can use the command-line interface as follows:

• Use the chsystem command with options -ntpip or -ntpip_6 to configure the NTP server address. Include the -ntpauthtype, -ntpauthkey and -ntpauthid options to configure authentication. To stop using NTP, set the address to 0.0.0.0.
• Use the command settimezone to set the time zone.
• Use the command setsystemtime to set the time and date manually.

This error is automatically fixed when a request to the NTP time server succeeds or if the time is set manually.
