Setting System Time

Setting System Time

This operation enables you to adjust the time and time zone of the system to be consistent with that of a client by modifying the cluster time and configuring the cluster time zone. By configuring the Network Time Protocol (NTP), the NTP server time can be automatically synchronized to the system. Configuring the NTP is optional, you can choose whether to configure it as your requirement.

Prerequisites

You have logged in to the DeviceManager as an administrator that has the permission. The following administrators have the permission:
  • Super administrator
  • Administrator
  • Device administrator

If interconnecting the external NTP server, make sure the server and the system management network are interworking.

Precautions

  • When the NTP service is configured, if the time difference between a cluster and the NTP server is greater than 10 minutes, manually modify the time of the cluster. Otherwise, the automatic time synchronization duration of the NTP server is too long. The cluster time can be changed either using the CLI or DeviceManager.
  • If the time difference between a cluster and the AD domain controller is greater than 10 minutes, manually modify the time of the cluster. The cluster time can be changed either using the CLI or DeviceManager.
  • If an NTP server is running in Windows, the time different between the server and cluster cannot be greater than 1000s; otherwise, an alarm will be raised. You can control the time different within 1000s using CLI or DeviceManager.

Procedure

  1. Log in to DeviceManager.
  2. Choose Settings > Cluster Settings > Basic Information > Time Settings.
  3. Setting system time.

    Table 16-2 describes related parameters.

    Table 16-2  System time parameters

    Parameter

    Description

    Value

    Cluster Time

    The value indicates the time of the system.

    [Value range]

    2000-01-01 to 2035-12-31

    [Example]

    2015-02-26 11:37:40

    Cluster Time Zone

    The value indicates the time zone of the system.

    [Example]

    (GMT+8:00)Asia/Chongqing

    NTP Service Switch

    Select Enabled. The following parameters will take effect.

    [Example]

    Enable

    NTP Version

    This parameter specifies the version of NTP.

    NOTE:
    By default, the version of the NTP is v4.

    [Value range]

    v3/v4

    [Example]

    v4

    Active NTP Network Address

    System time is synchronized to the active NTP network address of the system. After the active NTP network address is configured, click Test to test the connectivity between the system and the active NTP.

    NTP is a protocol used to synchronize the system time of a computer. A server that supports the NTP protocol can be an NTP server.

    [Value range]

    IPv4 address, IPv6 address, or domain name are supported. The domain name contains 1 to 255 letters, digits, periods (.), and hyphens (-) and cannot start or end with a hyphen (-). The top domain name cannot contain digits only.

    [Example]

    192.168.1.100 or fc00::1234 or test.com

    Standby NTP Network Address

    System time is synchronized to the standby NTP network address of the system. After the standby NTP network address is configured, click Test to test the connectivity between the system and the standby NTP.

    NTP is a protocol used to synchronize the system time of a computer. A server that supports the NTP protocol can be an NTP server.

    [Value range]

    IPv4 address, IPv6 address, or domain name are supported. The domain name contains 1 to 255 letters, digits, periods (.), and hyphens (-) and cannot start or end with a hyphen (-). The top domain name cannot contain digits only.

    [Example]

    192.168.1.100 or fc00::1234 or test.com

    1. Modify cluster time.

      1. Click Modify.
      2. In Modify Time dialog box, select the system time and click OK.

        The security alert dialog box is displayed.

      3. Confirm the information in the dialog box and select I have read and understood the consequences associated with performing this operation, and click OK.
      4. Click Close.

    2. In the Cluster Time Zone area, select a time zone and click Save.
    3. In the NTP Service Switch area, select Enable.
    4. In the NTP Version area, select the version of the NTP.
    5. In the Active NTP Network Address and Standby NTP Network Address area, set the network address or domain name of the NTP server and click Save.

      NOTE:

      You can click Test to test whether the server is available.
