Figure 5-13. An Array in Critical condition (left) and restored 
to Functional condition (right). 
Normally, the rebuild process begins automatically when you repair or 
replace the faulty disk drive. The Array recognizes the drive and begins the 
process a few moments later. 
If your RAID has a hot spare, the rebuild begins without waiting for a 
replacement drive. Be sure to replace the faulty drive as soon as possible. 
During the Rebuild process, the array is still available to read and write data 
but it may run noticeably slower. 
Manual Rebuild 
To initiate a manual Array rebuild: 
1.  In Tree View, select the Array icon 
 of the array 
you want to rebuild. 
2.  Right click on the icon and select Rebuild from the 
popup menu. 
OR Click the Rebuild Array 
 button in the 
Toolbar. 
3.  The Rebuild Wizard will assist you further. 
During the rebuild progress, the array will be available for use but it may run 
noticeably slower. If the beeper is enabled, it will beep slowly during this 
process. 
While the Array is synchronizing, it is still available to read and write data. If 
the beeper is enabled, it will beep slowly during this process. 
To turn the beeper on or off, right-click on the Controller icon 
 or the 
Enclosure icon 
 in Tree View and check or uncheck Beeper in the popup 
menu.
