Hi Bruce:
The control file is on single volume all by itself.
The problem always originates from one of our test systems in our
Test SYSPLEX.
The D U command shows nothing.
MIM and z/OS levels have been verified.
Thanks,

No, I have never experienced it but I have some thoughts. However, I
would be surprised if these haven't been suggested by one or more vendors.
* do you have any other datasets on the same volume as the control file?
* can you identify the system holding the RESERVE? Is it always the
same system? Anything unusual about the z/OS or MIM level on that system?
* on the system holding the RESERVE, does a console D U command show the
device as RESERVED (-R)? This would imply a software error (RESERVE
with no DEQ to release it).
