User's Manual

A dedicated hot spare is an unused backup disk that is assigned to a single virtual disk. When a physical
disk in the virtual disk fails, the hot spare is activated to replace the failed physical disk without
interrupting the system or requiring your intervention.
For more information on hot spares including size requirements, see Protecting Your Virtual Disk With A
Hot Spare. For considerations regarding RAID 10 and RAID 50 virtual disks created using the controller
BIOS, see Dedicated Hot Spare Considerations.
