Adaptec Storage Manager-Browser Edition
At the top of the Physical Devices view, grouped to the right of
View, are three view selection buttons 
. These buttons select how Adaptec Storage Manager displays the physical devices connected to this controller.
Hot Spares
Click the Hot Spare button 
to configure a drive or drives as hot spares. Hot spare drives are assigned to protect redundant arrays in the event of a drive failure. If a drive fails in a redundant array protected by a hot spare, the array will be rebuilt using the hot spare to replace the failing drive.
A hot spare can be assigned to protect a single array or all the arrays on the controller.
Changing How Drives are Displayed
When Adaptec Storage Manager is loaded, the Physical Devices view will default to display a condensed view of the controller configuration which hides detailed information about the drives. More information is available by either positioning the mouse pointer over the device or clicking on the arrowhead to the left of a row of devices.
The selected display mode button will appear in a lighter shade of blue than the other two buttons. The default display is the Text Description View 
, but in the condensed view used when Adaptec Storage Manager is loaded, the display is the same in all three modes.
If you change the display mode by selecting one of the other view buttons, a yellow arrow will flash to the left of any devices where the current condensed display prevents Adaptec Storage Manager from showing all the information available.
An icon is always the first entry on each device line. The 
icon is used to represent a hard disk drive. If a + symbol appears with the hard disk drive icon 
, the drive is a hot spare. Different icons are used to represent other devices.
