# Convert storage groups to cascaded

Storage groups are a collection of devices that are stored on the storage system. An application, a server, or a collection of servers use them.

## About this task

This procedure explains how to nondisruptively convert a stand-alone storage group to a cascaded storage group. Once completed, the original storage group serves as the parent to a new child storage group.

In eNAS operating environments, you can also perform this operation from Storage Groups for File page (System > System Dashboard > File Dashboard > File Storage Groups).

Before you begin:

- You must have Administrator or StorageAdmin permission.

To convert storage groups:

## Steps

1. Select the storage system.
2. Select Storage > Storage Groups.
3. Select the storage group, click , and click SG Maintenance > Convert to Cascaded.
4. Type a new name over the system-suggested child storage group name.
   Storage group names must be unique from other storage groups on the system and cannot exceed 64 characters. Only alphanumeric characters, underscores ( _ ), and (-) are allowed. Storage group names are case-insensitive.
5. For storage groups where the host I/0 limits have already been set (see Host I/O limits dialog box), click the Set on Parent radio button (the default) to set the host I/O limits for the parent storage group or click the Set on Child radio button to set the host I/O limits for the child storage group.
