We sometimes accidently turn on one linux guest on two z/VM systems.
Both z/VM system has their own DIRMAINT
The best solution for your problem is to couple the two systems with CSE, so
that they¹ll know what the other is doing.
Before we implemented CSE, we created a service we called Janus, which we
ran in the profile of each Linux server during the CMS startup. The purpose
was to look up which system
I have not yet implemented CSE to protect our linuxes from being started
on two different LPARs. I would be interested in getting a copy of your
Janus code.
Thanks for your assistance.

There is a IP conflict and dasd R/W conflict.
So it is the same as running two linux server sharing the same IP and the same
disks?
Exactly.
And z/VM has done

If you really have two guests up at the same time, using the same DASD, I
can't believe that one or both of them haven't crashed.

Bad, BAD idea. If they are in separate systems and the disks are shared R/W,
then they will corrupt each other, and probably damage both to the point of
