This Metalink Note ID is pretty good: 465001.1 -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Le Wen Sent: Wednesday, 17 June 2009 10:08 p.m. To: General Red Hat Linux discussion list Cc: General Red Hat Linux discussion list; redhat-list-bounces@xxxxxxxxxx Subject: RE: fixed drive name OK, my fault for not describing clearly.

So what's wrong? Also I have Oracle metalink id. Thanks everyone.

I can tell exactly what went wrong. Wait - no I can't. I get that it didn't keep sdb (do your disks change that often? What are you really trying to accomplish?) Are there any error messages? Can you paste your udev config and the output of scsi_id /dev/blockdevice ? As was said, udev is the right place to do this, you might just be missing a step.

In RHEL4, I can handle it using such method: 1. edit /etc/scsi_id.conf, change options=-b to options=-g 2. use command: scsi_id /block/sdb to get the scsi uuid of the hard drive, assume it returns 123456 3. create a rule file under /etc/udev/rules.d, which contains a line like BUS="scsi", PROGRAM="/sbin/scsi_id", RESULT="123456", NAME="sdb%n" 4. OK, each time I restart the server, the drive is fixed to sdb and never changes. However, in RHEL5, I can't do it anyway. So any clue?
