The information on this panel is self-explanatory. There are no userselectable properties for physical devices. Icons for other storage devices such as CD-ROM drives and DAT drives can also appear in the left panel. The Power Status property shows On when a drive is spun up and Powersave when a drive is spun down. Note that SSD drives and other drives that never spin down still show On.

When you select a virtual drive from the drop-down menu, the drive space used by that virtual drive is displayed in green. 9.5 Running a Patrol Read A patrol read periodically verifies all sectors of drives connected to a controller, including the system reserved area in the RAID configured drives. A patrol read can be used for all RAID levels and for all hot spare drives. A patrol read is initiated only when the controller is idle for a defined time period and has no other background activities. To start a patrol read, follow these steps: 9-16 Monitoring System Events and Storage Devices

Monitoring System Events and Storage Devices
The information on this panel is self-explanatory. There are no user-
selectable properties for physical devices. Icons for other storage devices
such as CD-ROM drives and DAT drives can also appear in the left
panel.
The
Power Status
property shows
On
when a drive is spun up and
Powersave
when a drive is spun down. Note that SSD drives and other
drives that never spin down still show
On
.
If the drives are in a drive enclosure, you can identify which drive is
represented by a drive icon on the left. To do this, follow these steps:
1.
Click the drive icon in the left panel.
2.
Click the
Operations
tab in the right panel.
3.
Select

The LED on the drive in the enclosure starts blinking to show its
location.
Note:
LEDs on drives that are global hot spares do not blink.
4.
To stop the drive light from blinking, select

All of the drive properties are defined in the Glossary.
To display a graphical view of a drive, click a drive icon in the left panel
of the MegaRAID Storage Manager window, and click the
Graphical

Running a Patrol Read
A patrol read periodically verifies all sectors of drives connected to a
controller, including the system reserved area in the RAID configured
drives. A patrol read can be used for all RAID levels and for all hot spare
drives. A patrol read is initiated only when the controller is idle for a
defined time period and has no other background activities. To start a
patrol read, follow these steps:
