I agree the MDISK is R/W to the Linux guest, so it is something happening
in Linux when the device is brought online. Can you check your UDEV rules
and see if there is one that would be associated with this device that
includes-- ATTR{readonly}="1" ?

Just like all the other mdisks... I'm pretty sure the problem is in Linux
somewhere

How is MDISK 012C defined in that Linux guest's directory entry? Can you
please include the output from "vmcp q v 12c"?
Thanks, Fred

When I configure device address 12c online it comes up ro. Why is this
occurring and how do I fix it ? I've deleted and recreated disk 12c
several times.
