Dell PowerFlex 4.5.x Administration Guide

Removing a resource group

1. On the menu bar, click Lifecycle > Resource Groups.
2. Select the resource group.
3. On the Resource Group Details page, under More Actions, click Remove Resource Group.
4. In the Remove Resource Group dialog box, select the Resource group removal type:
   • Delete Resource Group makes configuration changes to the nodes, switch ports, virtual machine managers, and PowerFlex to unconfigure those components. Also, it returns the components to the available inventory.
   • Remove Resource Group removes deployment information, but does not make any configuration changes to the nodes, switch ports, virtual machine managers, and PowerFlex. Also, it returns the components to the available inventory.
5. If you choose Remove Resource Group, perform the following steps:
   1. To keep the nodes in the inventory, select Leave nodes in PowerFlex Manager inventory and set state to and select the state:
      • Managed
      • Unmanaged
      • Reserved
   2. To remove the nodes, select Remove nodes from the PowerFlex Manager inventory.
   3. Click Remove.
6. If you choose Delete Resource Group, perform the following steps:
   1. Select Delete Clusters(s) and Remove from vCenter to delete and remove the clusters from vCenter.
   2. Select Remove Protection Domain and Storage Pools from PowerFlex to remove the protection domain and storage pools that are created during the resource group deployment.

      If you select this option, you must select the target PowerFlex gateway. The PowerFlex gateway is not removed. PowerFlex Manager removes only the protection domain and storage pools that are part of the resource group. If multiple resource groups are sharing a protection domain, you might not want to delete the protection domain.

      For a compression enabled resource group, PowerFlex Manager deletes the acceleration pool and the DAX devices when you delete the resource group.

   3. Select Delete Machine Group and remove from CloudLink Center to clean up the related components in CloudLink Center.

      CloudLink Center cleanup includes the deletion of the machine group, keystore, and approved network that is related to the resource group being deleted. These components are removed from CloudLink Center only if all the machines that are associated to the machine group are deleted first. If all the machines that are related to this machine group are not removed, the cleanup does not succeed as there are machines associated with the machine group.

   4. If you are certain that you want to proceed, type DELETE RESOURCE GROUP.
   5. Click Delete.
