PTF = Program Temporary Fix. IBM-Speak for a fix for a particular problem.

Thanks Kevin and Bob. PTF = minor version? I can’t think what it might stand for. Something Time Fix? Point in time fix?

Richard, I will second what Bob said with one caveat … on one occasion we had an issue with our multi-cluster setup because the PTF’s were incompatible. However, that was clearly documented in the release notes, which we obviously hadn’t read carefully enough. While we generally do rolling upgrades over a two to three week period, we have run for months with clients at differing PTF levels.

If I had to do my whole cluster at once, with an outage, I'd probably never upgrade. :) Bob Oesterlin Sr Storage Engineer, Nuance HPC Grid From: <[email protected]<mailto:[email protected]>> on behalf of "Sobey, Richard A" <[email protected]<mailto:[email protected]>> Reply-To: gpfsug main discussion list <[email protected]<mailto:[email protected]>> Date: Monday, August 15, 2016 at 4:59 AM To: "'[email protected]<mailto:[email protected]>'" <[email protected]<mailto:[email protected]>> Subject: [EXTERNAL] [gpfsug-discuss] Minor GPFS versions coexistence problems? Hi all, If I wanted to upgrade my NSD nodes one at a time from 3.5.0.22 to 3.5.0.27 (or whatever the latest in that branch is) am I ok to stagger it over a few days, perhaps up to 2 weeks or will I run into problems if they’re on different versions?
