Configuring Domain Groups

This chapter contains the following sections:

Domain Groups

Cisco UCS Central creates a hierarchy of Cisco UCS domain groups for managing multiple Cisco UCS domains. You will have the following categories of domain groups in Cisco UCS Central:

  • Domain Group — A group that contains multiple Cisco UCS domains. You can group similar Cisco UCS domains under one domain group for simpler management.

  • Ungrouped Domains — When a new Cisco UCS domain is registered in Cisco UCS Central, it is added to the ungrouped domains. You can assign the ungrouped domain to any domain group.

If you have created a domain group policy, and a new registered Cisco UCS domain meets the qualifiers defined in the policy, it will automatically be placed under the domain group specified in the policy. If not, it will be placed in the ungrouped domains category. You can assign this ungrouped domain to a domain group.

Each Cisco UCS domain can only be assigned to one domain group. You can assign or reassign membership of the Cisco UCS domains at any time. When you assign a Cisco UCS domain to a domain group, the Cisco UCS domain will automatically inherit all management policies specified for the domain group.

Before adding a Cisco UCS domain to a domain group, make sure to change the policy resolution controls to local in the Cisco UCS domain. This will avoid accidentally overwriting service profiles and maintenance policies specific to that Cisco UCS domain. Even when you have enabled auto discovery for the Cisco UCS domains, enabling local policy resolution will protect the Cisco UCS domain from accidentally overwriting policies.

Important:

  • Make sure to create a separate domain groups for all modular server domains. Also make sure the modular server domain groups are not hierarchical.

  • You must create separate infrastructure firmware policy for modular domains in Cisco UCS Central. The infrastructure firmware policies must be unique to modular servers. This will prevent any firmware policy resolution issues with other domain groups.

        Step 5   Click Change Group Membership.
        Step 6   In the Select Domain Group dialog box, do the following:
        1. Uncheck the check box for the domain group from which you want to remove the domain.
        2. Check the check box for the domain group to which you want to add the domain.
        3. Click Submit.

        Removing a Cisco UCS Domain from a Domain Group

          Step 1   On the menu bar, choose Physical > Compute.
          Step 2   In the left pane, expand Multi-Domain Managers.
          Step 3   In the left pane, expand UCS Central Accounts and then click the Cisco UCS Central account.
          Step 4   In the right pane, click the All UCS Domains tab. Then click the row in the table for the domain that you want to remove from a domain group.
          Step 5   Click Ungroup Domain.
          Step 6   In the UCSM Domain dialog box, click Submit.

          Creating a Registration Policy

          The registration policy contains the domain group policy qualifications for the domain group policies.

            Step 1   On the menu bar, choose Physical > Compute.
            Step 2   In the left pane, expand Multi-Domain Managers.
            Step 3   In the left pane, expand UCS Central Accounts and then click the Cisco UCS Central account.

            1. Click +. This displays the Add Entry to dialog box.
            2. In the Add Entry to dialog box, enter the minimum and maximum IP addresses and click Submit.
