Description Jack Neely 2007-02-27 00:41:00 EST
Description of problem:
I have installed a Promise SATA controller and 2 identical Seagate HDs in a Dell

  02:01.0 Mass storage controller: Promise Technology, Inc. PDC40718 (SATA 300
TX4) (rev 02)

The kernel correctly sees /dev/sda and /dev/sdb and I have done some tests to
partition and check for DOA HDs.  (Bad blocks test, etc.)

Anaconda from the FC6 CDs takes me to the partition configuration screens and
presents me with /dev/mapper/mpathp0 and /dev/mapper/mpath1.  This isn't right.

Version-Release number of selected component (if applicable):
anaconda (FC6 gold ISOs)

How reproducible:

Talked with pjones on irc a bit.  He suggested I try installing with the
"nompath" option to the boot kernel which did work.  I was able to install normally.

He also suggested that the serial numbers of my new hard drives were probably
the same, however they are indeed different.  I'm attaching the hdparm -I output
from both HDs.

Comment 6 Greg Diebel 2007-06-12 16:42:55 EDT
This happens for me on F7, using 2 identical Maxtor STM3160812AS 160GB SATA
drives. The board is Intel D945GCCR (no onboard RAID) As per #3, the drives do
not have identical serial numbers

Using nompath resolves the issue. If this situation occurs frequently with
multipath why is it the default?
Comment 7 Jack Neely 2007-06-12 16:48:30 EDT
I can confirm that my machine has the same bug in F7 as well.
Comment 8 Harold Pritchett 2007-06-12 19:34:13 EDT
I also have the same problem with F7.  Two Maxtor 500Gb drives to be formatted
as raid1 and LVM.  O/S to be installed on a third drive (80Gb WDC)

/dev/sda WDC WD800BB-32FRA0
/dev/sdb MAXTOR STM350063A
/dev/sdc MAXTOR STM350063A

Machine is a 5 year old P4 (TYAN S2090 Trinity i845 MotherBoard), 1.6 GHz P4
processor 1GB ram.

This bug is no longer reproducible in newer versions of Fedora.

FWIW: The comments in this bug regarding the "nompath" option (thank you!) helped me work around this very issue with my Fedora 10 install yesterday (February 9, 2009).  Until I ran the install with the nompath option I could not get Fedora to see my two 320gb SATA Maxstor drives.  I tried various BIOS settings and the nodmraid option which did not work.  I even dd if=/dev/zero of=/dev/sd[ab] when someone suggested "meta data" on the drives may be leading Fedora install program to only suggest /dev/mapper option.
