You *can* apply maintenance on a live system, but this is something you can do on a sandbox LPAR, certainly not on a production LPAR. And, even if you apply PTFs on a live sandbox LPAR, this practice is not recommendable. > How can you apply maintenance to omvs _and_ z/os from a different lpar?? AFAIK, this is the safest way to apply PTFs on a z/OS system; that is, from one LPAR to a 'dead' LPAR. The DDDEFs for datasets of the target (or dead) LPAR must point to the correct SYSRES volume. The DDDEFs for PATHs of the target (or dead) LPAR must be prefixed by something like '/service/' . Then, the zFS or HFS datasets of the target LPARs must be mounted on the /service/ mountpoint on the living LPAR where the apply job run. I believe this is a normal practice, which doesn't imply any risks.
