FC3+udev+SCSI ruleset woes

[T. Horsnell]

FC3 + 2.6.11-1.35_FC3smp on Tyan/Opteron more-or-less up2date.

Hi all,
I'm trying to make a udev rule which will rename one of my SCSI disk
device names. The rule is in /etc/udev/rules.d/local1-udev.rules
and says (as per the scsi_id man page):

BUS="scsi", PROGRAM="/sbin/scsi_id", RESULT="SSEAGATE ST3146707LC 3KS08QY100007443N4Q2", NAME="raid0"

This fails to generate the device /dev/raid0, but does generate a pile of
error messages thus:

Jul 20 18:40:30 ls1 udevsend[1898]: starting udevd daemon 
.
.

The RESULT string in the rule comes from 'scsi_id -s /block/sde'
so I was hoping for a match on that disk.

[root at ls1 ~]$ scsi_id -s /block/sde
SSEAGATE ST3146707LC    3KS08QY100007443N4Q2

Any ideas what I'm doing wrong? I've tried loads of perms and combs of 
keys in the rule, and can get it to work if I use the SYSFS{vendor}
and SYSFS{model}, but they, of course, match several drives and
I dont know how to make it more specific.

Cheers,
Terry.
