SLES9 on z/VM, autoyast and <dasd> section

Dear all,

We're trying to setup an SLES9 SP3 system
on a z/VM guest with autoyast. We would like to pre-defined an autoinst.xml
file.

It looks like the <dasd>...</dasd>
section is mandatory since autoyast does not get the dasd hardware settings
"on the fly". Unfortunately we don't know the mdisk id a priori,
so that we currently are modifying the autoinst.xml file manually for every
system with a different mdisk id.

Replacing the autoinst.xml file with
a new one during the pre-installation step (as described in the SLES documentation)
does not work since hardware detection is done before pre-installation.
Simply omiting the <dasd>...</dasd> section did not work since
yast stops working after hardware detection since it does not detect any
disk to install the system on. I tried to add a dasd= (resp. DASD=) parameter
to the parmfile but it doesn't help detecting the disks.

Does anybody know what we could do to
omit that <dasd>...</dasd> section from the autoinst.xml file?
Can we specify the mdisk id in that section with a placeholder? Or has
it really to be hardcoded in the autoinst.xml file?

    <dasd>
      <devices config:type="list">
        <listentry>
          <channel_id>0.0.0150</channel_id>
          <diag
config:type="boolean">false</diag>
          <format
config:type="boolean">true</format>
        </listentry>
      </devices>
    </dasd>
