The drive ordering is based more on the device ordering from the pci bus scan and sata init. Check what cat /proc/scsi/scsi says. I bet the new sdb even though it's in a sata#3 socket has a lower lun than sata#2.<br><br>
And yes, this is why the transition to UUID is happening for distros like Fedora. I think Ubuntu also does drives by UUID as well. For some reason I don't find UUID=c2a3c3bd-414c-4c30-a83c-38e69551808a easier to read than /dev/sda<br>

Here is something that happened to me strange today.<br>
<br>
We have a server we are using to run VMware Server 2.0. It has<br>
2 250GB SATA drives used as a RAID1 array. These devices are sda<br>
and sdb.<br>
<br>
I noticed an ad at MicroCenter for a 1TB SATA drive @ $129. We took<br>
the ad to Fry's in Alpharetta and they matched the priced. I installed<br>
the drive in the 3rd SATA port on the MB. I booted Linux and for some<br>
odd reason Linux made the 1TB drive sdb and pused the old sdb to sdc.<br>
Not a real problem because the md driver was able to figure this out. I<br>
thought maybe the vendor who build the server plugged the cables in wrong<br>
but I checked and everything looked good.<br>
<br>
Is there a reason this happened? Can I force a drive to a device<br>
name by using a command line argument while booting Linux?<br>
<br>
On another note, I can't believe that a 1TB drive can be had for $130!<br>
We are going to use it to backup non-critical data.<br>
