Rebuild
When you rebuild a disk array, you are actually rebuilding the data on one physical drive.
• When a physical drive in a disk array fails and a spare drive of adequate capacity is available, the disk
array begins to rebuild automatically using the spare drive.
• If there is no spare drive of adequate capacity, but the Auto Rebuild function is ENABLED, the disk array
begins to rebuild automatically as soon as you remove the failed physical drive and install an unconfigured
physical drive in the same slot. See “Making Rebuild Settings” below.
• If there is no spare drive of adequate capacity and the Auto Rebuild function is DISABLED, you must
replace the failed drive with an unconfigured physical drive, then perform a
Manual Rebuild
.
