Removing virtual servers

Before you unmanage a chassis that is under IBM® Flex System Manager management software management, you should remove all of the virtual servers that are associated with the compute nodes.

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 virtual server instances for each compute node in the chassis that you want to unmanage, complete the following steps.

Note: If you just completed the procedure in Removing guest operating system instances on virtual servers, the inventory for the virtual servers is already displayed in the management software web interface. Skip to step 5.
  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 Server. The inventory table changes to display the servers and virtual servers that are related to the compute nodes.
  6. In the table, select the boxes for all of the virtual servers.
    Note: To reorganize the table so that all of the virtual servers are listed together, sort the table by clicking the arrows in the heading for the Type column.
  7. Select the boxes for all of the virtual servers; then, click Actions > Chassis > Remove.... The virtual machine operating systems are deleted.
    Note: For Power Systems™ compute nodes, you must first remove the host server from the IBM Flex System Manager management before removing the virtual servers and their associated Operating System managed endpoints (if any). To remove the host, complete the following steps:
    1. Select the Virtual Server to be removed.
    2. Click Actions > Remove Resources > Server.
    3. Select the host Power Systems compute node.
    4. Click Actions > Remove....
    5. Click OK when you see the removal confirmation. The Power Systems compute node, associated virtual servers, and associated operating system managed endpoints will be removed from the IBM Flex System Manager interface.

After you complete the preceding procedures, and the compute node operating systems, compute node guest operating systems, and virtual servers for the compute nodes have been removed from management, you can unmanage the chassis. See Using management domains for more information about unmanaging a chassis.
