Err... You don't need to play with the drivers/CAM stuff, why not try the natively supported gpt(8), which works great. - Map the RAID device to a single SCSI device - Do a dd if=3D/dev/zero of=3D/dev/da0 bs=3D16384 count=3D16 to wipe the M= BR - Do a `gpt create /dev/da0' to create your GPT partition table - Do a `gpt add /dev/da0' to create a GPT partition over it - You will now see something like /dev/da0p1, which can be used for subsequent disklabel(8), or just newfs -U /dev/da0p1 Cheers, --=20 Xin LI <delphij frontfree net> http://www.delphij.net/ See complete headers for GPG key and other information. --EeQfGwPcQSOJBaQU Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQFCpwhg/cVsHxFZiIoRAqeuAJ93UH9gQHIRl1YSAvPcKj3YvX5vUACfWr8R eGC07a+w65heUorZxEbUTTE= =Vea5 -----END PGP SIGNATURE----- --EeQfGwPcQSOJBaQU--
