Date: Mon, 24 Jul 2000 21:06:27 +0200 Message-ID: <6890.964465587@critter.freebsd.dk> From: Poul-Henning Kamp Sender: owner-freebsd-arch@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Matt, We have many storage devices which doesn't sport a serial number, so any "I mean this particular disk, no matter where you find it" scheme will have to be based on "in-sector" labels, be it FreeBSD or other labels. The BSD disklabel already have a field for disk-name which can be used for this, what we need is to collect these names as we see them and provide a "is this disk attached and if so where" function to look it up. This would be pretty ugly in the current setup, but pretty straight forward in the "Geom" stuff I'm working on when I have time. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD coreteam member | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
