Why am I telling you this?
A good reminder:
RAS is only important,
when you hit a failure
then it is absolutely vital
Raspberry Pi RAS nothing like POWER RAS
but then it only costs 50€$£

Ansible for AIXOn the AIX Open Source Toolbox- Open Source version – doh! [CLI based Engine]IBM just released LOTS of AIX and VIOS Playbooks
If you want Enterprise Class RedHat Ansible [Engine] with certified Playbooks- Runs on RHEL- - but can control AIX
Red Hat Ansible Tower (full browser based GUI) is available too
Open source version of Ansible Tower called AWX is available on POWER8/POWER9- But on RHEL 7 or RHEL8 on POWER- From Power Dev-Ops friends- https://www.power-devops.com/- https://www.power-devops.com/ansible-awx

lparstat reporting Dynamic Perf mode is a known bug in lparstat and (I think a couple of other).So Dynamic Performance mode = Max Performance mode on POWER9.
Don’t Panic!
POWER9 Max == Dynamic

AIX User Meeting 2 UPDATE
Can you help? PLEASE!
Older Open Source RPM packages don’t mix with the new AIX Toolbox RPMS
1. Been told stop workloads
2. Remove all the older RPMs completely
3. Add Yum from the official YUM Bundle
4. Add the RPMs you removed but only from the AIX Toolbox
5. Life is good
Exposes underlying hard mistakes!
Still working on this – update next time

Fun facts or favourite features!
AIX has a rmss command – Reduced Memory Size Simulator
usage: rmss [-s startmemsize] [-f finalmemsize] [-d deltamemsize][-n numiterations] [-o outputfile] command
rmss -c memsize
rmss -r
rmss -p
Note that the rmss command is incompatible with the AIX DLPAR
component, and its usage may result in a hung system. The drmgr command provides a safe memory removal function in a
DLPAR environment.
