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 50.
To create a spare drive, see “Create Spare Drive” on page 113.
For more information, see “Hot Spare Drive(s)” on page 194.
Notes
• You can add physical drives to a RAID 50 array but you
cannot change the number of axles.
• If you add an odd number of physical drives to a RAID 10
array, it will become a RAID 1E array by default.
