controllers in the left panel of the MegaRAID Storage Manager window. If the controller
is operating normally, the controller icon looks like this: . If the controller has failed,
a small red circle appears to the right of the icon. (See Section7.2.1,
Dashboard/PhysicalView/Logical View for a complete list of device icons.)
To display complete controller information, click a controller icon in the left panel of the
MegaRAID Storage Manager window. The controller properties display in the right
panel, as shown in Figure187.
Figure 187: Controller Properties
Most of the information on this screen is self-explanatory. Note the following:
The Rebuild Rate, Patrol Read Rate, Reconstruction Rate, Consistency Check Rate, and
BGI Rate (background initialization) are all user selectable. For more information, see
Section8.4, Changing Adjustable Task Rates.
The BBU Present field indicates whether a battery backup unit is installed.
The Alarm Present field and the Alarm Enabled field indicate whether the controller
has an alarm to alert the user with an audible tone when there is an error or
problem on the controller.
The controller properties are defined in Appendix C.
