View CKD volume details

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

Steps

  1. Select the storage system.
  2. Select HOSTS > Mainframe.
  3. Select a CKD volume and click 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 Storage Group opens a view listing the storage groups that are associated with the volume.
