5.3.1.3
Hot-spare drive in RAID1 or RAID5 systems
A hot spare drive is a drive included in the device as spare.
If you have ordered a device with a hot-spare drive, your device is equipped with this hot-
spare drive in the factory state.
If a defective drive is detected in the RAID1 or RAID5 system, the hot-spare drive is
automatically integrated instead of the defective drive during operation and assumes its
function.
Data synchronization to the hot-spare drive starts automatically.
