If nodes from each or two partitions access the same disk -- even if they
only read and don't write data -- it is likely that not only the consistency
(correct data) of the file will be lost, but its integrety also (meaning
the file could become unreadable). The term "file" refers to both RMS files
and database files.
You really do not want to circumvent the protections that OpenVMS provides
to help you avoid partitioned clusters. Really!
