Rebuild Rate
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 uncongured
physical drive in the same slot.
• If there is no spare drive of adequate capacity and the Auto Rebuild function is DISABLED, you must
replace the failed drive with an uncongured physical drive, then perform a Manual Rebuild.
backgrounD synchronIzatIon
Synchronization is automatically applied to redundant logical drives when they are created. Synchronization
recalculates the redundancy data to ensure that the working data on the physical drives is properly in sync.
