Removing guest operating system instances on virtual servers

If your compute nodes have virtual servers with guest operating systems, remove guest operating system instances on the virtual servers that are managed by the hypervisor on each compute node before you unmanage a chassis that is under IBM® Flex System Manager management software management.

If none of the compute nodes in the chassis have virtual servers, you can skip the process that is described in this topic and unmanage the chassis. See Using management domains for more information about how to unmanage a chassis.

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 guest 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 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. Click Actions > Inventory > View and Collect Inventory. The page refreshes, and the virtual servers are now listed in the Target systems field at the top of the page.
8. In the navigation tree in the Collected Items box, expand Related Systems; then, click Operating System. The virtual machine operating systems are displayed in the table.
   Note: If the Operating System option is not displayed as an option in the View by field, there are no operating systems for the compute nodes. Skip to Removing virtual servers.
9. Select the boxes for all of the operating systems; then, click Actions > Remove.... The virtual machine operating systems are deleted.
