disks are standby hard disks that can repair a degraded volume/Disk Group/iSCSI LUN by
automatically replacing a failed disk. Hot spare disks can be globally assigned to protect any volume/Disk
Group/iSCSI LUN within your IoSafe NAS, as long as the volume/Disk Group/iSCSI LUN matches the following
criteria:
The RAID type of the volume/Disk Group/iSCSI LUN must be one with data protection (i.e. RAID 1, RAID 5,
RAID 6, RAID 10).
The hot spare disk size must be equal to or larger than the size of the smallest disk in the volume/Disk
Group/iSCSI LUN.
