With a Hot Spare Drive
When a physical drive in a logical drive fails and a spare drive of adequate
capacity is available, the disk array will begin to rebuild automatically using the
spare drive. This function is always enabled.
After the logical drive rebuilds itself using the spare drive, you must replace the
failed drive.
To set up a spare drive, see “Creating a Spare Drive” on page 78 or page 137.
