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 Locate Physical Drive, and click Go.
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 Stop Locating Physical
Drive, and click Go.
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
View tab. In Graphical View, the drive's storage capacity is color coded
according to the legend shown on the screen: configured space is blue,
available space is white, and reserved space is red. When you select a
virtual drive from the drop-down menu, the drive space used by that
virtual drive is displayed in green.
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:
