{{DISPLAYTITLE:Marking/Unmarking Hot-spares for Hardware RAID Units}}
Marks the specified disk for use as a Universal hot-spare by ZFS based storage pools.  Universal spares can be used by any storage pool in the appliance and when you have multiple appliances connected to shared SAS storage then universal spares can be shared across pools across appliances.
Hardware RAID units require hot-spares to be configured within the RAID controller. To toggle marking/un-marking of the specified disk as a hot-spare simply right-click on a disk within the controller and choose ''Mark/Unmark Hot-spare''.  Note that devices marked as hot-spares within a RAID controller can only be used as a hot-spares for RAID units managed by that specific controller.  As such if a system has two or more RAID controllers each one will need one or more disks marked as hot-spares in order to get automatic healing of RAID units.  Systems using fault-tolerant software RAID at the Storage Pool level using HBAs have no requirement to specify hardware RAID hot-spares and in such cases this section does not apply.
