Setting the date and time

  1. Last updated
  2. Save as PDF

You can change the date and time for the controller clock and the SVP clock.

Changing the controller clock settings

Complete the following steps to change the date and time on the storage system controller.

Caution
  • If you change the system date and time when the currently set date and time is after the real time, the configuration information might not be backed up. To prevent this from happening, move the existing backup file to another folder and then change the system date and time.
  • The date and time cannot be changed while a different user is accessing the storage system.
  • If you use the SVP, make sure to also update the system date and time on the SVP.
  • To use the NTP server, make sure to use the port number 123 for communications between the storage system and the NTP server. Therefore, configure the network settings between the storage system and the NTP server so that the communications using the port number 123 are established.

Before you begin

  • You must have the Storage Administrator (View & Modify) role to perform this task.

Procedure

  1. In the maintenance utility Administration tree, select Date & Time.

    The current settings are displayed.

  2. Click Set Up.

  3. Change the settings as needed, and either click Apply to save them, or click Cancel to close the window without saving the changes.

Changing the SVP clock and time zone settings

If your configuration includes an SVP for external management servers, you need to ensure that the clock and the time zone settings on the SVP match those of the controller clock.
NoteThe SVP supports Simple Network Time Protocol version 4 (SNTPv4) for date and time synchronization.

Before you begin

  • The management client must be connected to the LAN 2 port on the SVP.
  • The management client must have already established a remote desktop connection with the SVP. Note that the connection cannot be established when you use Remote Desktop Session Host.
  • If storage systems are registered in the Storage Device List, click Stop Service for all registered storage systems in the Storage Device List window before changing the SVP clock settings.

Procedure

  1. Log in to the management client that is connected to the SVP.

  2. On the Windows 8.1 desktop, click Start Control Panel.

  3. Click Clock, Language, and Region.

  4. Click Date and Time.

  5. Click Change date and time.

  6. In the Date and Time Settings window, set the date and time, and then click OK to save the settings.

  7. Click Change time zone.

  8. In the Time Zone Settings window, select the time zone, and then click OK.

    NoteIf you do not restart the background service, the time zone change is not reflected. When the time zones remain different between the SVP and the storage system, this condition can cause error conditions.
