Using management domains

Use the Management Domain page in the IBM® Flex System Manager management software web interface to establish or change your chassis-management configuration.

Note: This topic describes how to access this task in the IBM Flex System Manager Web user interface. If you are using the IBM FSM Explorer, use the finder at the top of the user interface (shown here) to locate this task:

A management domain consists of the Flex System Enterprise Chassis hardware and resources that are under management by the management software.

Access the Management Domain page by using one of the following methods:
  • From the Home page, click the Initial setup tab; then, click Select Chassis to be Managed.
  • From the Home page, click the Plug-ins tab; then, click the Management Domain link under IBM Flex System Manager.
You can use the Management Domain page in the management software web interface to perform the following chassis-management actions:
  • Manage or unmanage a chassis
    Notes:
    1. Before you unmanage a chassis, make sure that you complete the procedures that are described in Unmanaging a chassis. Otherwise, the compute nodes in that chassis will not be removed from the management software.
    2. A CMM can be managed only by one management node at a time. Additionally, if a CMM is managed by one management node, and you want to manage it with another management node, you must first unmanage the CMM on the initial management node Management Domain page. After you click Unmanage, you might have to use the lschassisind command to clear the settings that link that CMM to the initial management node. After you clear the settings, you can click Unmanage for the initial management node; then, you are able to manage the CMM with the new management node.
  • View a list of all chassis (including those that are unmanaged and those that are managed by another management node in your environment)
    Note: After initial discovery, if a chassis is unmanaged from another management node and added to the management network of your management node, click the Discover New Chassis button to refresh the list of chassis.
  • Go to the Chassis Manager page for another management node
  • Go to the Chassis Map view for a chassis, regardless of which management software manages it
Important: 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 the local subnet, make sure that the IP address that is assigned to Eth0 is on the same IPv4 subnet or IPv6 network as the IP address that is assigned to the CMM. 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.
To discover a chassis manually, complete the following steps:
  1. From the Home page, click the Plug-ins tab.
  2. Under Discovery Manager, click System Discovery.
