Selecting chassis for management

The Management Domain page enables you to select which Flex System Enterprise Chassis to manage.

About this task

You can use the IBM® Flex System Manager management software to select one or more discovered chassis for management. On the Home page, click Select Chassis to be Managed; the Management Domain page opens. The Management Domain page lists the names and Chassis Management Module (CMM) IP addresses of discovered chassis.

The Management Domain page also has one management option check box:
Authenticate using the Flex System Manager user registry
Select this box before you click Manage if you want to configure the chassis for centralized user management mode. If you select this option and click Manage, a Request access window opens and you are required to enter administrator account credentials.
Note: The default credentials are the administrator user ID and password that you established in the setup wizard. Make sure that you log in with the administrator account credentials that will be used to access the CMM after centralized management is complete; this account will be logged in the audit trail.
For more information about how the CMM is configured in centralized user management mode (including the RECOVERY_ID account), and for details about changing centralized management settings, see Using centralized user management. For an overview of centralized user management mode, see Centralized user management.

An IPv6 Unique Local Address (ULA) is set on each chassis component when the chassis is centrally managed. The IPv6 ULA is required for the management node to have routable IP addresses on the management network to communicate with each chassis component. The IPv6 ULA is set with the same 64-bit prefix as the chassis CMMs.

After you select the chassis that you want to manage and select the configuration options for the chassis, click Manage.

Important:
  1. The Management Domain page displays only the Flex System Enterprise Chassis that are on the same local subnet as the management node. To manage a chassis on another subnet, you must first discover the chassis manually. After the chassis is discovered, it appears in the chassis list on the Management Domain page.
  2. When you manage a chassis that has an IBM Flex System V7000 Storage Node installed, the management software overwrites the preexisting SSH key for the user ID superuser. After the management process is complete, you can reapply the previous SSH key.

For more information about how to change the user management mode of a managed chassis from decentralized to centralized, see Changing the user management mode of a managed chassis.

To discover a chassis manually, complete the following steps:
  1. On the Management Domain page, select the Discover New Chassis button.
  2. Select the Add or remove remote chassis option.
  3. Add the IP address of the remote chassis and select the Add option.
  4. When all the remote chassis IP addresses are added, select the Save and Discover button.
Attention: If the chassis is not added to the Management Domain page after discovery, verify that the chassis is reachable on the management network from the management node.
Note: If one or more chassis are not shown in the table, make sure that a Chassis Management Module (CMM) in the chassis is cabled to the top-of-rack switch in your hardware configuration. See Cabling the chassis for more information.
For more information about managing a remote chassis on a different subnet than the management node, see Managing a remote chassis.

For information about changing the user management configuration from decentralized to centralized, or centralized to decentralized, see Changing the user management mode of a managed chassis.
