SCSI Scan order wrong

Asked by Eric Bursley

During a fresh installation of Ubuntu 10.04, I noticed that the Linux kernel is scanning and registering the hard drives incorrectly.

In my Dell Precision workstation 690, I have 4 500GB SATA hard drives configured in two RAID 1 sets.

/proc/scsi/scsi shows the following:

Host: scsi8 Channel: 01 Id: 02 Lun: 00
  Vendor: Dell Model: VIRTUAL DISK Rev: 1028
  Type: Direct-Access ANSI SCSI revision: 05
Host: scsi8 Channel: 01 Id: 00 Lun: 00
  Vendor: Dell Model: VIRTUAL DISK Rev: 1028
  Type: Direct-Access ANSI SCSI revision: 05

Id: 00 Lun: 00 is showing as /dev/sdb
Id: 02 Lun: 00 is showing as /dev/sda

This caused two problems during the install. One when I configured my boot partition, I had to set it to /dev/sdb. Grub failed to install to /dev/sdb, so I had to manually install grub into /dev/sdb before I got a bootable system.

I can provide what ever logs you need to debug this.
Presently my system is bootable, but still is showing the same wrong scsi scan order.

Bug #575146 status changed in linux in ubuntu:

    New => Confirmed

Status change explanation given by Philip Muškovac:

Thank you for taking the time to report this bug and helping to make
Ubuntu better. Unfortunately, we can't fix it without more information.

Please run the following command which will attach necessary
information:

apport-collect 575146

Bear in mind that when prompted to give apport-collect permissions for
Launchpad you will need to give it at least the ability to "Change Non-
Private" data as it will be adding information to your bug report.

If you cannot use apport please at least add the following information (pay attention to lspci's additional options):
First run the following commands:
1) uname -a > uname-a.log
2) dmesg > dmesg.log
3) sudo lspci -vvnn > lspci-vvnn.log
4) cat /proc/version_signature > version.log
then attach the files separately to the bug report (not pasted into comments or tar/zip-ed).

For your reference, the full description of procedures for kernel-
related bug reports is available at
https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies. Thanks in
advance!
