Adding or removing NTP servers

You can use the IBM® Flex System Manager management software web interface to add or remove a Network Time Protocol (NTP) server in your IBM Flex System environment.

Note: If you add an NTP server, you must set your keyid and password on the NTP server to match the keyid and password that you set in the management software. The process for setting the key ID and password varies by operating system. For example, if your external NTP server is running Linux, and if your keyid is 1234 and your password is my_password, you would typically modify /etc/ntp.keys by adding the line 1234 M my_password and modify /etc/ntp.conf by adding the line trustedkey 1234.

For more information about setting the keyid and password on your NTP server, see the documentation that came with your NTP server.

Note: The IBM Flex System Manager management software can point to a remote NTP server. However, all the chassis components including the CMM must directly point to the IBM Flex System Manager management software and not to the NTP server.
To add or remove an NTP server in the web interface, complete the following steps:
  1. From the Home page, click the Administration tab.
  2. Under Configuration tasks, click Configure Date/Time. The Date/Time Configuration page opens.
  3. Click the Time Server tab. The time servers that are defined in the Network Time Protocol (NTP) configuration file are displayed in the table.
  4. On the Time Server tab, the following actions are available:
    Add an NTP server
    Click Add to define a new NTP server. In the Add Time Server window, enter the settings for the NTP server; then, click OK.
    Remove an NTP server
    To remove an NTP server, select the button for the server; then, click Remove. Click OK.
    Configure an NTP server to manage the date and time
    To configure an NTP server to manage the date and time, select the button for the time server; then select the Enable NTP service box below the table. Click OK.
    Note: The poll interval for the NTP service cannot be configured manually.
  5. If you are prompted, restart the management node.
