Check if you have PTF UM32790 for z/VM540. It is on the 1002 RSU.
Are you using HYPERPAV? If so, removing HYPERPAV volume use from your VM LPAR
should resolve the problem.
We had similar problem and the applying 1002 RSU service fixed

If it shows r/w and is still not working, log the guest off and back on.
If it works then, that would indicate it is some kind of RH problem and Linux

If it still does not work, check the VM

That's easy...

The words M Multiple-write access are somewhat misleading. MW stands for
Multiwrite. M is Multiple, you wil *not* get a link when some other user has
a R/W link. With MR, one gets a R/O links when another R/W link exists.
In this case, Linux had

Good ideas!
Again, the console log would lead to the footprint of the perp that

Which leads to another place that might tell... if you have an ESM

attempts.
For example
the mount command fails.
