Each storage class definition specifies an aggregate type. When you create an Infinite Volume with a storage class, only the type of aggregate specified for the storage class can supply storage for the volume. You must understand storage class definitions to create aggregates that are appropriate for the storage class.
Storage class definitions are available only in OnCommand Workflow Automation. After you understand the aggregate requirements for each storage class, you can use the command-line interface or OnCommand Workflow Automation to create aggregates for storage classes. However, you must use OnCommand Workflow Automation, not the command-line interface, to create an Infinite Volume with one or more storage classes.
When you use OnCommand Workflow Automation to create an Infinite Volume with a storage class, OnCommand Workflow Automation automatically filters the aggregates available in the cluster based on the storage class that you want to use. If no aggregates meet the requirements of the storage class, you cannot create an Infinite Volume with that storage class.
