Hot spares are only activated in response to a fault received by the zfs-retire FMA agent. There is no notion that the spares should be re-evaluated when they become available at a later point in time. Certainly a reasonable RFE, but not something ZFS does today. You can 'zpool attach' the spare like a normal device - that's all that the retire agent is doing under the hood.
