Removing operating system instances for each compute node

Before you unmanage a chassis that is under IBM® Flex System Manager management software management, you should remove the operating system instances for the operating systems that are running on each compute node.

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:

To remove the operating system instances for each compute node in the chassis that you want to unmanage, complete the following steps:

  1. From the management software web interface, click the Chassis Manager tab. The Chassis Manager page opens.
  2. Select the box for the chassis that you want to unmanage; then, click Actions > Related Resources > Server.
    Note: You can also right-click the name of the chassis to open the Actions menu.
    The Resource Explorer page opens, which displays a list of the compute nodes in the chassis.
  3. Click Actions > Select All to select all of the compute nodes in the table.
  4. Click Actions > Inventory > View and Collect Inventory. The View and Collect Inventory page opens. The Target systems field is pre-populated with the compute nodes in the chassis.
  5. In the navigation tree in the Collected Items box, expand Related Systems; then, click Operating System. The inventory table changes to display the operating systems that are related to the compute nodes.
    Note: If there are no operating systems displayed in the inventory table, there are no operating systems for the compute nodes. Skip to Removing guest operating system instances on virtual servers.
  6. Click Actions > Select All to select all of the operating system instances.
  7. Click Actions > Remove... to remove the operating system instances.

Proceed to Removing guest operating system instances on virtual servers for information about how to remove guest operating system instances on the virtual machines that are managed by the hypervisor on each compute node.
