# View thin volume details

A storage volume is an identifiable unit of data storage. Storage groups are sets of volumes.

## About this task

This procedure explains how to view thin volume details.

## Steps

1. Select the storage system.
2. Select STORAGE > Volumes.
3. Filter on a thin volume type, such as TDEV.
4. Select a thin volume and click to open its Details view.
