8.4.1 Advanced volume functions
Click Volumes (as shown in Figure 8-41 on page 375) and the Volumes window opens, as
shown in Figure 8-42.
Figure 8-42 Volume window
By default, this window lists all configured volumes on the system and provides the following
information:
򐂰 Name: Shows the name of the volume. If there is a + sign next to the name, this sign
means that there are two copies of this volume. Click the + sign to expand the view and list
the copies, as shown in Figure 8-43 on page 377.
򐂰 Status: Provides the status information about the volume, which can be online, offline, or
degraded.
򐂰 Capacity: The disk capacity that is presented to the host. If a blue volume is listed next to
the capacity, this means that this volume is a thin-provisioned volume. Therefore, the listed
capacity is the virtual capacity, which might be more than the real capacity on the system.
򐂰 Storage Pool: Shows in which Storage Pool the volume is stored. The primary copy is
shown unless you expand the volume copies.
򐂰 UID: The volume unique identifier.
򐂰 Host Mappings: Shows if a volume has host mapping: Yes when host mapping exists
(along with small server icon) and No when there are no hosting mappings.
Important: If you right-click anywhere in blue title bar, you can customize the volume
attributes that are displayed. You might want to add some useful information, such as,
Caching I/O Group and Real Capacity.
