Hi Jennifer ,

Did you setup the /etc/sysconfig/hardware/hwcfg-zfcp-bus-ccw-0.0.5000 file ?
You can do that using YAST or editing the file .
The second point is a recommendation : Setup the Linux OS devices has
mini-disks ( / , /var , /usr , etc ... ) and the data at scsi . You can
setup it as EDEV in VM if you do not have FICON connections .

Best Regards,
