Deleting a Group
You must drop all hosts assigned to a group before you can delete a group.
To delete a group, follow these steps:
Log into the Admin Interface.
Click the Hosts icon on the left tree menu.
Check that there is not a host assigned to the group you wish to delete. All hosts assigned to a group must be dropped before the group can be deleted. Dropping a host from a group does not drop the host from the cluster.
Click the Groups icon on the left tree menu.
Click the name of the group that you want to delete, either from the menu tree of from the Group Summary page.
Click the Configure tab.
Click delete. A confirmation message appears.
Click ok to permanently delete the group.
Deleting a group is a hot operation; the server does not need to restart to reflect your changes.
