Removing a resource group

Edit online

You can remove a resource group from an active cluster. You do not need to stop and then restart cluster services for the resource group to be removed from the current cluster configuration.

About this task

To remove a resource group:

Procedure

  1. From the command line, enter smit sysmirror
  2. In SMIT, select Cluster Applications and Resources > Resource Groups > Remove a Resource Group and press Enter.

    SMIT displays a panel listing the defined resource groups.

  3. Select the resource group you want to remove and press Enter. SMIT displays a popup warning, reminding you that all information about the resource group will be lost.
    Note: If you have the following parent/child resource group dependency chain configured: A > B > C, and remove the resource group B, PowerHA® SystemMirror® sends a warning that the dependency links between A and B, and between B and C are also removed.
  4. Press Enter again to confirm your action.
  5. Return to previous SMIT panels to perform other configuration tasks.
  6. Synchronize the cluster configuration.

Results

If Cluster Services is running on the local node, synchronizing cluster resources triggers a dynamic reconfiguration event.
