Hey, all --
This is returning to an old question for me, as I've started creating
10.1 installation profiles now that the zypp/zmd issues seem to be
fixed.
I'm trying to install onto a server with the following:
- 2 x 80GB SATA, on a Silicon Image controller, exported as JBOD.
- 3 x 250GB SATA, on a 3ware 9550 controller, exported as a single RAID
5
I'm creating a software RAID 1 on the 80GB drives, and using that as the
root partition.  The RAID5 being partitioned for LVM, though not
allocated yet.
When autoyast starts the install, it autodetects the installed hardware
(in, I think, alphabetical order?).  The 3ware RAID array is detected as
/dev/sda, and the two SiI disks as /dev/sdb and /dev/sdc
When the install is complete and the system reboots, this order has
switched; the SiI disks are /dev/sda and /dev/sdb, and the 3ware RAID is
/dev/sdc.
You have to load the modules for your controllers in the right order. Put
them
into the <initrd_modules> section in your profile in the proper order, the
3ware module first and then the other one.
Well, I'm hoping to have the 3ware RAID as /dev/sdc, so I have my initrd_modules section set up this way:
    <initrd_modules config:type="list">
      <initrd_module>
        <module>amd74xx</module>
      </initrd_module>
      <initrd_module>
        <module>sata_sil</module>
      </initrd_module>
      <initrd_module>
        <module>3w_9xxx</module>
      </initrd_module>
      <initrd_module>
        <module>processor</module>
      </initrd_module>
      <initrd_module>
        <module>thermal</module>
      </initrd_module>
      <initrd_module>
        <module>fan</module>
      </initrd_module>
      <initrd_module>
        <module>jbd</module>
      </initrd_module>
      <initrd_module>
        <module>ext3</module>
      </initrd_module>
      <initrd_module>
        <module>raid1</module>
      </initrd_module>
    </initrd_modules>

But it looks like it doesn't apply to the autoinstall process; the detection order is correct after the first installed boot, but not during the install process itself...
