Hi Mark, I had tried that echo command but the system would not allow me to change the file. I ended up rebooting before seeing this message, that cleared whatever was preventing me from configuring it on r/w and allow me to format etc.

If not, you can put udev into debug mode to see if you can get more information that way. It may also be worthwhile to execute echo 0 > /sys/bus/ccw/devices/0.0.012c/readonly and see what happens.
