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: . .

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