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 An icon showing the letter i to open the Details view.

    The Details view links you to views displaying objects contained in and associated with the virtual volume. Each link is followed by a number, indicating the number of objects in the corresponding view. For example, clicking the number next to Storage Group opens a view listing the storage groups that are associated with the volume.
