[gentoo-user] Extra IDE card, drives out of order

[gentoo-user] Extra IDE card, drives out of order

[Wes Gray]

I added an extra IDE controller card so I could get a 5th drive.  It's a
Silicon Image chipset (CONFIG_BLK_DEV_SIIMAGE).  When I boot into the kernel
with the module included the kernel sees the IDE channels on the new card as
the first ones and the existing IDE channels on my motherboard as the
additional ones.  So to the new kernel it sees:

/dev/hda (newly added drive)
/dev/hdb (no drive)
/dev/hdc (no drive)
/dev/hdd (no drive)
/dev/hde (my old /dev/hda)
/dev/hdf (my old /dev/hdb)
/dev/hdg (my old /dev/hdc)
/dev/hdh (my old /dev/hdd)

The kernel tries to boot off the first drive on the new controller card
instead of my boot drive, which is odd because the kernel that is running is
read off of my old /dev/hda which the new kernel sees as /dev/hde.  So the
BIOS and Grub see them in the correct order.  Hope that makes sense.  Perhaps
I could fix the problem by moving all of my drives to the new IDE card, not
sure and that's not my preferred solution.  My kernel is vanilla 2.6.15.1.

Thanks for any help.

Are you using udev? If so, you can use rules to define what you need.
Check:
http://www.gentoo.org/doc/en/udev-guide.xml and
http://reactivated.net/writing_udev_rules.html

They helped me a lot...

For grub the (hd0,0) entry is always the device the BIOS is booting.
So, its not strange, its default behavior.

You shouldn't, try booting from a LiveCD or so and writting your rules...

Remove the new card and drives then rebuild your kernel.  What 
you're looking for is IDE chipset support/bugfixes -> boot offboard 
first (make sure this is not set).

I don't think that will work.  The rules would reside in /etc on my boot drive,
and the kernel would never see them because it isn't seeing the boot drive
as the boot drive, it sees it as /dev/hde.  I think the change has to be
something in the kernel.

I didn't have that set.
