After adding the volumes through yast and putting them online with chccwdev, I
worked happy with them till IPL. Unfortunatelly, yast don't give that
informational massage, or I was to quick.
It was tricky to make changes to /etc/fstab when in PCOM, but we managed
to create version without that partition with: grep -v dasdf1 /etc/fstab >
/etc/fstab.temp
So, now I added to my procedure mkinitrd and zipl.

Are you sure you don't have to:
mkinitrd
zipl
ANY time you make changes to volumes?
I do which yast would, at least, give you an informational message
telling you that you need to do those steps when you add/chg/delete
dasd. Sometimes I too quick to IPL and as I start the shutdown
process...Nooooo!

Hello,
can you say, what will add the dasd permanently?
I added one dasd (through Yast - ACTIVATE - SLES9).
After reboot, that dasd is not activated at the same time when others,
so
it can't be mounted in /etc/fstab.

That file is not writable anymore in Linux 2.6., and it's going to go
away
entirely in the future (tool lsdasd will replace reading
/proc/dasd/devices).
The same operation can be performed via sysfs:
"echo 1 >/sys/bus/ccw/drivers/dasd/<device>/online"
Given that sysfs is deep nested, the tool chccwdev provides a more
user
friendly way of enabling a device.
Both operations do _not_ add the volume permanently: it will be
vanished
after
reboot again...
