Following the procedures below worked perfectly. I then proceeded to take
the dasd_fba_mod and add it to the /etc/sysconfig/kernel file and ran
mkinitrd to ensure that everything is there. I now have a swap device on
VDISK at system startup. -- Of course I added the entry in /etc/fstab....
Thanks to all who helped.

Subject: Re: SLES8 VDISK issue
Eric,
I remember seeing some issues with the 64bit kernel and the diag driver.
We
are just doing the equivalent of the following:
modprobe dasd_fba_mod
echo "add device range=292" >> /proc/dasd/devices
mkswap /dev/dasdg
swapon /dev/dasdg
The bottom line is that the vdisk is an fba type device. If you're not
running the 64bit, or have the correct patches, then you can do the same
with the diag driver.
