First you need to disklabel da0s1 and da1s1 because you have created a slice fdisk partition table. And you might to wipe out the first blocks of a slice to create a virgin disklabel. E.g. dd if=/dev/zero bs=64k count=10 of=/dev/da1s1 Finaly you want to read the Handbook section about adding new disks - it's all explained there. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
