The Logical Devices View
When you select the iSCSI Storage Appliance in the Enterprise View, the pools and
logical devices associated with that appliance appear in the Logical Devices View.
(A pool is a collection of disk drives combined in a RAID set. A logical device is
created within a pool and is seen as a single iSCSI target.)
The RAID level of a logical device is indicated by the number inside the logical
device’s icon. For instance, the logical device shown at right has RAID 1.
Pools protected by hot spares have plus signs (+) beside them, as shown at
right.
With tool tips enabled (see page 141), hold your cursor over any pool to see its
name and size; hold your cursor over any logical device to see its name, size,
and status. You can also click the arrow, shown at right, to view this same
information for all pools or logical devices at the same time.
Select a pool to highlight the disk drives that comprise it in the Physical Devices
View, and the logical device created from it in the Logical Devices View.
You can also select any disk drive to see which (if any) pool it belongs to. A disk
drive shaded in light blue is not part of any pool.

The selected pool includes four disk drives and has been used to create
three logical devices.
