Removing compute nodes from cloud groups

You can remove one or more compute nodes from a cloud group when the compute node is no longer needed.

Before you begin

You must be assigned Cloud group administration role with permission to View all cloud groups (Read-only permission) to remove compute nodes.

About this task

To remove a compute node from its cloud group, the compute node must be powered on and quiesced before you switch it to maintenance mode. To successfully switch into maintenance mode, you must evacuate all virtual machines running on that compute node to other compute nodes in the same cloud group. A virtual machine will not migrate successfully if no other compute nodes in the cloud group has sufficient resources to host it. If a virtual machine cannot be migrated, you must manually stop and store the virtual machine before its compute node can go into maintenance mode.
Important: If you want to remove all compute nodes from a cloud group, you must first remove all data stores associated with that cloud group.

Procedure

  1. Quiesce the compute node.
    See Starting and quiescing compute nodes.
  2. Put the compute node into maintenance mode.
    See Putting compute nodes into maintenance mode.
  3. Click Cloud > Cloud Groups. If you are on 2.3.3.3, navigate to Cloud > Architecture > Cloud Groups.
  4. From the list of available cloud groups, select the one from which you want to remove the compute node.
  5. In the Compute nodes section, select the compute node from the menu list.
  6. Click the Delete icon to remove the compute node from the cloud group. Click OK to verify that you want to remove the compute node.
