Sorry but you can't. Once the spare is assigned to a raid set it cannot be assigned to another raid set.

Re: Shared Hotswap
hi bob
there is no way to share any drives across multiple controllers. each controllers firmware can handle only local drives attached to the controller.
-------------------------------------------
a single smart controller supports local spares, global spares ( a spare is assigned to multiple logical drives) and with new firmware even multiple spares within a single logical drive.
----------------------------------------
this even works across multiple channels, but all drives must be connected to a single controller
----------------------------------------
as you can only connect one cable to a backplane (two if the bus is split - but still one cable per segment), there is no physical connection between the scsi busses of two separate controllers
---------------------------------------
as a result, controllers CANNOT share spare drives.
