Linux does not need to know about the real device numbers -- it sees
only the virtual device numbers.  The fact that you've DEDICATEd the
DASDs with the same virtual device number as it's real device number is
probably helping to confuse you. ;)

In the directory for your LNXCAPD guest, the minidisk you have defined
on real DASD 2061 will have a virtual device number.  This is the number
that must appear in the "dasd=" line.  It does not need to be the same
number as the real device number of the host DASD (and should not really
be: after all, the minidisk can reside on any suitable DASD).  As Mike
and Carsten both indicated, the order of numbers in the "dasd=" line
will determine which DASD shows up as dasda, dasdb, dasdc, etc.

If the installer had added the dasd parameter line it used to the
zipl.conf it created, you might have had some help toward knowing what
was needed.
The dasd parameter "missing" from zipl.conf has caught me out on a
couple of occasions.  After install the system boots fine (the installer
having built the initrd/boottext correctly), but the first time you run
zipl (say, for a kernel update) stops the machine from booting.  When
the dasd parameter is not provided the driver senses all DASD, and when
you use the de-facto standard of Linux disks starting at 200 your CMS
disks (191 and friends) pop in ahead and b0rk up your DASD naming...

If you have moved part of your system (/usr, /var, etc) into the LVM,
you will need to run mkinitrd to ensure that the LVM activation commands
are added to the initrd.  This will make sure that all required
filesystems are available for the boot to complete.
