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 .
