OceanStor 2800 V5 V500R007

This document is applicable to OceanStor 2800 V5. Routine maintenance activities are the most common activities for the storage device, including powering on or off the storage device, managing users, modifying basic parameters of the storage device, and managing hardware components. This document is intended for the system administrators who are responsible for carrying out routine maintenance activities, monitoring the storage device, and rectifying common device faults.

Setting the Device Time

Setting the Device Time

If the system time of the storage system is inaccurate, change the system time of the storage system. In this way, when alarms are generated, you can accurately determine the alarm generation time based on alarm logs. This operation allows you to synchronize the client time to the storage system and set NTP automatic synchronization or manually change the system time.


  • Complete the NTP server configuration before setting NTP automatic synchronization. For details about the operations, see related configuration documents of the NTP server.
  • In an environment with the firewall function, when the NTP automatic synchronization function is enabled, you need to enable port 123.


  • Network time protocol (NTP) is a computer system time synchronization protocol, which can synchronize the computer system time to universal time coordinated (UTC). The server supporting and running the NTP is referred to as the NTP server.
  • By synchronizing the client time, you can adjust the storage system time to be consistent with the client time.
  • By configuring the NTP automatic synchronization, you can periodically and automatically synchronize a storage device with the NTP server which serves as an external time source.


  1. Log in to DeviceManager.
  2. Choose Settings > Basic Information > Device Time.
  3. Configure the storage device time.

    After this operation is executed, if the device time changes, the following impacts may be triggered:

    • If the changed device time exceeds the license validity period, the license may be invalid.
    • If the changed device time exceeds the certificate validity period, the certificate may expire.
    • If the changed device time exceeds the password validity period set by a user, the system may force the user to change the login password.

    The storage device time can be configured in the following ways:

    • Synchronize client time

      Select Synchronize client time.


    If DeviceManager cannot obtain the time zone ID, Time Zone is displayed. Set Time Zone to the time zone of the place where the client resides.


    For detailed operations of configuring automatic synchronization of the NTP server time, see section Configuring the NTP Service of the Installation Guide of the corresponding product model.

    • Manually modify time
      1. Select Manual.
      2. Click Modify.

        The Modify Time dialog box is displayed.

      3. Change the storage device time.
        • In the Date group box, change the device date.
        • In the Time group box, change the device time.
        • From the Current Time Zone drop-down list, select the time zone of the storage device.
      4. Click OK.

  4. Set NTP automatic synchronization

    1. Select Set NTP automatic synchronization.
    2. Type the IPv4 address, IPv6 address or domain name of the NTP server in NTP Server Address.
      • A maximum of two NTP servers can be added. If the time of the one NTP server cannot be automatically synchronized to devices, the system synchronizes the time of another NTP server to devices.
      • Ensure that the time of two NTP servers is consistent.
    3. (Optional) Click Test.
    4. (Optional) In NTP Authentication, select Enable.

      Only when NTPv4 or later is used, NTP authentication can be enabled to complete identity authentication for the NTP server and automatically synchronize the system clock to storage devices.

    5. Check the time difference between the NTP server and storage device and check the server status.
      • The function is supported by V500R007C20 and later versions.
      • If you have modified the NTP configuration, query the NTP server status one minute after the configuration is saved.
      • If the time difference is not 0, time is being synchronized. If the time difference is 0, time synchronization has been completed.
      • The plus sign (+) indicates that the storage system time is earlier than the NTP server time. The minus sign (-) indicates that the storage system time is later than the NTP server time.

  5. Confirm the device time setting.

    1. Click Save.

      The Warning dialog box is displayed.

    2. Confirm the information in the dialog box and select I have read and understand the consequences associated with performing this operation.
    3. Click OK.

      The Execution Result dialog box is displayed indicating that the operation succeeded.

    4. Click Close.
