This window lists all configured volumes on the system and provides the following  information: Tip:  Right-click anywhere in the blue title bar to customize the volume attributes that are  displayed. You might want to add useful information, such as the caching I/O group and  the real capacity. 2. To create a volume, click  Create Volumes  and complete the steps that are described in  Chapter 6, “Volume configuration” on page 309. 3. Right-clicking or selecting a volume and opening the Actions menu shows the available  actions for a volume, as shown in Figure 8-37. – Capacity: The disk capacity that is presented to the host. If a thin provisioned or  compressed volume exists, an icon is shown next to the capacity. Therefore, the listed  capacity is the virtual capacity, which might be larger than the real capacity on the  system. – Host mappings: Shows whether a volume has host mapping:  Yes  when host mapping  exists and  No  when no hosting mappings exist. – UID: The volume unique identifier. – Pool: Shows in which storage pool the volume is stored. The primary copy, which is  marked with an asterisk (*) is shown unless you expand the volume copies. – Synchronized: For mirrored volumes, whether the copies are synchronized. – State: Provides the status information about the volume, which can be  online ,  offline ,  or  degraded . – Name: Shows the name of the volume. If a twistie sign (>) appears before the name,  two copies of this volume exist. Click the twistie sign (>) to expand the view and list the  volume copies, as shown in Figure 8-36 on page 407.
