Replacing and rebuilding a hard disk drive (Models xx4)
Note: Before beginning these procedures, complete one of the two methods to
determine the failed hard disk drive.
Follow the steps in the “Replacing a hard disk drive” on page 38 to remove and
replace the failing hard disk drive.
After the operating system loads, the RAID application rebuilds the hard disk drive
automatically. During this process, you can use the machine normally. Rebuilding
time varies depending upon the size of the partition, the amount of data, and the
system activity during the rebuild. See Figure 50 on page 70.
