I have already formatted, deleted, recreated, reformatted, change real addr etc
from VM, and I do not see any related messages in the server console log
either. Someone mentioned the rules, I think the rules are created
dynamically, when I config it offline I think the rules disappear. After
configuring online I get this rule
# Configure DASD device at 0.0.012c (ECKD mode)
ACTION=="add", SUBSYSTEM=="ccw", KERNEL=="0.0.012c", IMPORT{program}="collect
0.0.012c %k 0.0.012c dasd-eckd"
ACTION=="add", SUBSYSTEM=="drivers", KERNEL=="dasd-eckd",
IMPORT{program}="collect 0.0.012c %k 0.0.012c dasd-eckd"
ACTION=="add", ENV{COLLECT_0.0.012c}=="0", ATTR{[ccw/0.0.012c]online}="1"

I think the suggestion was to reformat it or erase it outside of Linux (i.e
using CMS FORMAT, CPFMTXA or ICKDSF INIT).
Are there any interesting messages in the virtual machine console log at boot
time? If you unmount and remount it, does it stay R/O? If R/O wasn't
requested on a mount, Linux only goes R/O when it encounters a problem, and it
is pretty noisy about such things.
