Peter, Simon, While I believe Power9 / RHEL 7.5 will be supported with the upcoming PTFs on 4.2.3 and 5.0.1 later in June, I'm working on getting confirmation for that.

They are running rhel7.5 but on an old kernel I guess. I'm not sure that 4.2.3 works on power 9 we've asked the IBM power 9 out reach team but heard nothing back. If we can get 4.2.3 running on the power 9 nodes it would put us in a more consistent setup. Of course our current plan b is to upgrade everything to 5.0.1, but we can't do that as our storage appliance doesn't (officially) support spectrum scale 5 yet. These are my experiences of what works and nothing whatsoever to do with what's supported, except I want to keep us as close to a supported setup as possible given what we've found to actually work.

We’ve just ordered some Power 9 nodes, now my understanding is that with 7.4, they require the -ALT kernel ( https://www.ibm.com/support/knowledgecenter/en/linuxonibm/liaam/liaamdistros.htm ) which is 4.x based. I don’t see any reference in the Spectrum Scale FAQ to the ALT kernels. So what Scale code is supported for us to run on the Power9s?

The efixes will then be provided once the internal tests on RHEL 7.5 have been completed, likely a few days before the 4.2.3.9 and 5.0.1.1 PTFs GA (currently targeted around mid June).
