This window lists all configured volumes on the system and provides the following information: 

– 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. 

– State: Provides the status information about the volume, which can be online , offline , or degraded . 

– Synchronized: For mirrored volumes, whether the copies are synchronized. 

– 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. 

– UID: The volume unique identifier. 

– Host mappings: Shows whether a volume has host mapping: Yes  when host mapping exists and No  when no hosting mappings exist. 

– 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. 

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.
