Writing 1 MB of zeros to the raw disk device has always been enough to make sure a drive is treated as new.
My experience is mostly with FreeBSD, but a zpool export .. reboot .. zpool import [-f] cycle has fixed up things for me before. Or zpool clear <device> ..... On Solaris based systems I understand the FMA may need to be examined or cleared.
