Physical/Logical View Panel
The left panel of the MegaRAID Storage Manager window displays either the
Physical view or the Logical view of the system and the devices in it, depending
on which tab is selected.
• The Physical view shows the hierarchy of physical devices in the system. At the
top of the hierarchy is the system itself. One or more controllers are installed in
the system. Each controller has one or more ports. Disk drives and other devices
are attached to the ports.
• The Logical view shows the hierarchy of controllers, virtual disks, and disk groups
that are defined on the system. (Physical drives also appear in the Logical view,
so you can see which physical drives are used by each virtual disk.)
The following icons in the left panel represent the controllers, disk drives, and other
devices:
• System
• Controller
• Port
• Array
• Virtual disk
• Physical drive
A red circle to the right of an icon indicates that the device has failed.
A yellow circle to the right of an icon indicates that a device is running in a de-
graded state.
