This topic explains how to create and delete instances by using the Advanced Settings Utility.
Use the set command to create an instance. If the instance does not already exist, and the instance number is between 1 and the maximum number of allowed instances, the instance is automatically created and set to the value specified in the set command.
Use the delete command to delete an instance. This command deletes the instance if deleting the instance does not cause the number of instances for the setting to go below the minimum number of allowed instances for the setting.
