Try those steps:
1. attach DASDs (e.g. #cp def t3390 <vdev> <cylinders>) to VM guest
2. set DASDs online
3. perform lowlevel format with "-d ldl" option
4. set DASDs offline
5. load "dasd_diag_mod" module
6. set DIAG on for those DASDs
echo 1 > /sys/bus/ccw/devices/0.0.0400/use_diag
echo 1 > /sys/bus/ccw/devices/0.0.0401/use_diag
7. activate DASDs
chccwdev -e 0400,0401
lsdasd

Hi again, couldn't help trying to turn on DIAG mode also.
Have been trying that before without any success.
So I tried it here as well for an extra disk /xd, but did not work so well:
Usage: /sbin/dasd_configure <ccwid> <online> <use_diag>
zlin1040:~ # dasd_configure 0.0.020c 1 1
Configuring device 0.0.020c
Setting device offline for DIAG access
Could not set the device offline for DIAG access (Ok , needs unmounted of
course)
zlin1040:~ # umount /xd
zlin1040:~ # dasd_configure 0.0.020c 1 1
Configuring device 0.0.020c
Setting device offline for DIAG access
Activating DIAG access mode
Setting device online
Could not activate DIAG access mode for device 0.0.020c <--- :(
Setting device online
zlin1040:~ # mount /xd
zlin1040:~ #
Do I need to do something special to have DIAG mode on ?
Before SLES11 there was some requirements when formatting the disk, but that
didn't help either.
Does someone have succeeded in having DIAG ON ?

It goes into the udev configuration - in this case a file named
"/etc/udev/rules.d/51-dasd-0.0.0210.rules" should have been created.
I believe YaST takes care of this as well, if you choose to go through YaST,
but I'm not absolutely sure about that one.

Thank's a lot !
That did the trick.
Does this mean I have to do this every time I add a disk, or was it because
I used
native cmds instead of yast ?
Yast ( or dasd_configure ) must be putting this info in some hidden place
??

I believe that for SLES 11 zipl.conf is no longer used to determine which
dasd to online at boot. Instead, however, you can run `dasd_configure
0.0.0210 1` before you run mkinitrd and zipl, and the specified disk should
be set online and come back online on subsequent boots.

I can't say I remember it, but I usually do due to prev. mistakes....
However, after making disk online and mounting everything, I have run
mkinitrd and zipl.
Also compared the result with the clone base machine, and it looks the
same.
It seams SLES11 does not save all disks in zipl config, just the boot
device... hmmm
I'm suspicious here, but don't know what to look for...

Hi Tore,
chccwdev -e 210
mount -a
Did you run mkinitrd & zipl after bringing the disk online and mounting
it
?
