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.
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. This operation is initiated only when
the controller is idle for a defined time period and has no other background activities.
You can set the patrol read properties and start the patrol read operation, or you can
start the patrol read without changing the properties.
To set the patrol read properties and then start a patrol read, follow these steps:
1. Click a controller icon in the left panel of the MegaRAID Storage Manager main
menu.
2. Select Go To>Controller>Set Patrol Read Properties.
