## Performing actions on volumes 

From the Volumes window, you can perform various tasks on the volumes. Click Actions  to access these operations (see Figure 7-81), or right-click the volume name, which opens a list of tasks that you can perform on the volume.

The properties of a volume that indicate the volume name, its capacity, and its sector size are shown in Figure 7-82. Each volume features a unique ID (UID), which can be discovered from the host side as a property of the logical unit. The volume that is shown in Figure 7-82 is not yet mapped to a host.

A volume can be expanded while it is online, which maintains full functionality to the connected hosts. Because not all operating systems allow concurrent expansion of their disks, precautions must be taken so that the operating system supports dynamic volume expansion. An alternative to expanding the disk is to create an additional disk and map it to the host. 

Attention:  FlashSystem 900 volumes support a maximum of eight extents. This means that you can expand a volume up to seven times.
