Rebuilding a Disk Array

When you rebuild a disk array, you are actually rebuilding the data on a replacement physical drive.

To enable Auto Rebuild, see “Making Background Activity Settings” on page 133.

To create a spare drive, see “Creating a Spare Drive” on page 173.

For more information, see “Hot Spare Drive(s)” on page 239.
