Managing Time Zones

This chapter includes the following sections:

Date and Time Policies

Cisco UCS Central supports global date and time policies based on international time zones and defined NTP server. Registered Cisco UCS Manager clients choosing to define date and time globally within that client's policy resolution control will defer the configuration for date and time to its registration with Cisco UCS Central.

Configuring a Date and Time Policy

Before You Begin

Before configuring a date and time policy under a domain group, this policy must first be created. Policies under the Domain Groups root were already created by the system and ready to configure.

Procedure
    Step 1   On the menu bar, click Operations Management.
    Step 2   In the Navigation pane, expand Domain Groups > Domain Group root.
    Step 3   Under the Domain Groups root node, do one of the following choices:
    • To configure the policy in the domain group root, click Operational Policies.
    • To configure the policy in a specific domain group, expand the node for that domain group and click Operational Policies.
    Step 4   In the Navigation pane, click Operational Policies.
    Step 5   In the Work pane, click DateTime.
    Step 6   In the Actions area, click Create and complete all applicable fields.

    For Operational Policies under the Domain Group root node, it is not necessary to click Create to complete all applicable fields.

    Name Description

    Create button

    Creates an instance of the policy that will be used by all Cisco UCS domains included in the selected domain group.

    Import button

    Allows you to import the policy from one of the Cisco UCS domains registered with Cisco UCS Central.

    Delete button

    Deletes the instance of the policy defined for the selected domain group.

    After you delete the policy, it remains greyed-out until you click Save. When you do so, Cisco UCS Central deletes the policy and any configuration data you may have specified. While you can create a new instance of the policy later, you cannot restore the configuration data from a deleted instance.

    To cancel the delete request, click Reset.

    Time Zone drop-down list

    Select the appropriate time zone from the list.

    Filter button

    Allows you to filter the data in the table. When you apply a filter, this button name changes to Filter (on).

    Add NTP Server button

    Allows you to add an NTP server to the selected domain group.

    Properties button

    Displays detailed properties for the object selected in the table.

    Delete button

    Deletes the object selected in the table.

    Name column

    The hostname or IP address of the NTP server.

    Step 7   Click Save.

    Deleting a Date and Time Policy

    A date and time policy is deleted from a domain group under the domain group root. Date and time policies under the domain groups root cannot be deleted.

    Deleting a date and time policy will remove all NTP server settings within that policy.

    Procedure
      Step 1   On the menu bar, click Operations Management.
      Step 2   In the Navigation pane, expand Domain Groups > Domain Group root.
      Step 3   Expand the node for a domain group containing the policy to delete.
      Step 4   In the Navigation pane, click Operational Policies.
      Step 5   In the Work pane, click DateTime.
      Step 6   In the Actions area, click Delete.

      A policy that is deleted will inherit its settings from its domain group's parent until it is reconfigured.

      Step 7   If Cisco UCS Central GUI displays a confirmation dialog box, click Yes.
      Step 8   Click Save.

      Configuring an NTP Server for a Date and Time Policy

      Before You Begin

      To configure an NTP server for a domain group under the domain group root, a date and time policy must first have been created.

      Procedure
        Step 1   On the menu bar, click Operations Management.
        Step 2   In the Navigation pane, expand Domain Groups > Domain Group root.
        Step 3   Under the Domain Groups root node, do one of the following choices:
        • To configure the policy in the domain group root, click Operational Policies.
        • To configure the policy in a specific domain group, expand the node for that domain group and click Operational Policies.
        Step 4   In the Work pane, click DateTime.
        Step 5   In the Actions area, click Add NTP Server and complete all fields.
        1. In the Add NTP Server dialog box, complete all fields.
          Name Description

          NTP Server field

          The IP address or hostname of the NTP server you want to use.

          Note   

          If you use a hostname rather than an IP address, you must configure a DNS server. If the Cisco UCS domain is not registered with Cisco UCS Central or DNS management is set to local, configure a DNS server in Cisco UCS Manager. If the Cisco UCS domain is registered with Cisco UCS Central and DNS management is set to global, configure a DNS server in Cisco UCS Central.

        2. Click OK.
        Step 6   Click Save.

        Configuring Properties for an NTP Server

        An existing NTP server's properties may be updated before saving an NTP server instance. To change the name of an NTP server that is saved, it must be deleted and recreated.

        Procedure
          Step 1   On the menu bar, click Operations Management.
          Step 2   In the Navigation pane, expand Domain Groups > Domain Group root.
          Step 3   Under the Domain Groups root node, do one of the following choices:
          • To configure the policy in the domain group root, click Operational Policies.
          • To configure the policy in a specific domain group, expand the node for that domain group and click Operational Policies.
          Step 4   In the Navigation pane, click Operational Policies.
          Step 5   In the Work pane, click DateTime.
          Step 6   In the Actions area, select the NTP server to configure, click Properties and complete all fields.

          You can also right-click the NTP server to access that option. The Properties (NTP Provider) dialog accessed by clicking Properties in the in the Actions area cannot be edited if the NTP server has been saved. To change the server name of an NTP server that was saved, delete and recreate the NTP server.

          1. In the Properties (NTP Provider) dialog box, complete all fields.
            Name Description

            NTP Server field

            The IP address or hostname of the NTP server you want to use.

            Note   

            If you use a hostname rather than an IP address, you must configure a DNS server. If the Cisco UCS domain is not registered with Cisco UCS Central or DNS management is set to local, configure a DNS server in Cisco UCS Manager. If the Cisco UCS domain is registered with Cisco UCS Central and DNS management is set to global, configure a DNS server in Cisco UCS Central.

          2. Click OK.
          Step 7   Click Save.

          Deleting an NTP Server for a Date and Time Policy

          Procedure
            Step 1   On the menu bar, click Operations Management.
            Step 2   In the Navigation pane, expand Domain Groups > Domain Group root.
            Step 3   Under the Domain Groups root node, do one of the following choices:
            • To configure the policy in the domain group root, click Operational Policies.
            • To configure the policy in a specific domain group, expand the node for that domain group and click Operational Policies.
            Step 4   In the Work pane, click DateTime.
            Step 5   In the Actions area, select the NTP server to delete and click Delete.

            You can also right-click the NTP server to access that option. An NTP server that is deleted will inherit its settings from its domain group's parent until it is reconfigured.

            Step 6   If Cisco UCS Central GUI displays a confirmation dialog box, click Yes.
