Disk Array Rebuild
When you rebuild a disk array, you are actually rebuilding the data on one disk
drive. Normally, a disk array would rebuild itself using a hot disk drive, after going
Critical. However, if the Auto Rebuild function is disabled or no spare drives are
available, you must initiate the procedure.
To enable Auto Rebuild, see “Background Activities” on page 71.
To create a spare drive, see “Create Spare Drive” on page 146.
For more information, see “Hot Spare Drive(s)” on page 247.
