3.4.2 Viewing Extents on a Volume (Extents Tab)

An extent (also known as a “physical extent”) is a contiguous set of logical blocks (LBs)

When a volume is selected in the Main Display, you can use the Extents tab to view
information about the extents on the selected volume. Initially, the Extents tab shows
basic extent information, as shown in Figure 3-30. This read-only screen provides drive
links below the first Description column that, when clicked, display the selected drive
in the Extents tab of the Physical Storage View (see section 3.4.2).
