Controller
The Controller deals with creating new Arrays, reading events from the memory
buffer, setting cache and performance options. Array creation is covered in the
Arrays section of this chapter.
View Event Log
The Controller's Memory Buffer records all the events that happen on the RAID,
classified as Errors, Warnings and Information. These are very useful for
diagnosing and solving problems on your system.
To see the Event Log, right-click on the Controller icon
select Read Events from the popup menu.
Figure 53. The Event Viewer.
In the Event Viewer, you can view the events, make a permanent record by
saving them to a file, and clear the events from the Viewer. You can also clear
the events using the popup menu in Tree View.
Note that the collecting and reporting of these Events is independent from the
Alert Notification preferences set for the RAID System.
Read Bad Sector Table
To see the Bad Sector Table, right-click on the Controller icon
and select Read Bad Sector Table from the popup menu.
In the Bad Sector Table, you can view the bad sectors or media errors on disk
drives discovered during Rebuild operations. With this information you can
decide whether a disk drive is OK to keep in use or you need to replace it.
Note that the collecting and reporting of this information is independent from the
Alert Notification preferences set for the RAID System.
