A cell must contain at least one core group. The CoreGroupManagement command group for the AdminTask object includes the following commands:

• createCoreGroup

• deleteCoreGroup

• doesCoreGroupExist

• getAllCoreGroupNames

• getCoreGroupNameForServer

• getDefaultCoreGroupName

• moveClusterToCoreGroup

• moveServerToCoreGroup
