A global hot spare is an unused disk that is part of the disk group. Hot spares remain in standby mode. When a hard drive that is used in a virtual disk fails, the assigned hot spare is activated to replace the failed hard drive without interrupting the system or requiring your intervention. When a hot spare is activated, it rebuilds the data for all redundant virtual disks that were using the failed hard drive.
You can change the hot spare assignment by unassigning a disk and choosing another disk as needed. You can also assign more than one hard drive as a global hot spare.
To assign or unassign a global hot spare for a hard drive, complete the following steps: Does my controller support this feature? See Supported Features.
