Modifying resource groups

Modify resource groups to refine resource allocations used in your resource plan. You may also want to add or remove hosts from resource groups if you have recently added or removed hosts in your cluster.

Before you begin

You must be logged in as a cluster administrator or have the Resource Groups Manage permission to modify a resource group.

1. From the cluster management console, choose your navigation based on whether the resource group is used for slot-based scheduling or multidimensional scheduling:
   • To view hosts in a resource group used for slot-based scheduling, select Resources > Resource Planning (Slot) > Resource Groups.
   • To view hosts in a resource group used for multidimensional scheduling, select Resources > Resource Planning (Multidimensional) > Resource Groups.

   Any existing resource groups display.

2. Click the name of the resource group you want to modify.

   The resource group settings display.

3. Change any settings you want.
   For slot-based resource groups, follow these guidelines:

   • If you choose Static (List of Names), see Create a resource group by host names.

     You cannot modify the number of slots per host while any of the group's resources are allocated to consumers.

   • If you choose Dynamic (Requirements), see Create a resource group by resource requirement.

     You cannot modify a group with dynamic membership while any of the group’s resources are allocated to consumers.

   For multidimensional resource groups, follow the guidelines in Creating multidimensional resource groups.

4. When you are satisfied with your settings, click Apply.

What to do next

Using the cluster management console, ensure that your resource plan is correct based on the changes you made to the resource groups.
