When an Oracle FS System starts up for the first time after installation, that system has one Storage Domain that contains all of the drive groups that are available in the system. That domain is referred to as the default Storage Domain. You can create additional Storage Domains by removing one or more of those drive groups from the default domain and adding them to new Storage Domains.
Remove drive groups from the default Storage Domain and add those drive groups to the Storage Domain.

You can create a Storage Domain without drive groups. Such a Storage Domain contains no storage capacity and therefore cannot be assigned to a logical volume.
