Migrating #AIX to 7.2 TL4 - Be aware that sendmail has changed. Non-root users may not be able to send mail.
If you edit privcmds file, you need to run setkst after to update the kernel security tables.

Anybody else seeing this error from PHA clcycle command?
I see it at PHA 7.2.2 SP2, any other 7.2.2 levels affected?
# clcycle
The cluster log entry for clxd.log could not be found in the HACMPlogs ODM.

After installing #VIOServer 3.1.0 I noticed that the ssh host keys are included in the mksysb image, therefore unless you delete them and recreate them, all your VIO Servers will have the same host keys.

Dedicated donating LPARs, LPM changes share_idle_procs_always to share_idle_procs. Meaning active LPARs stop donating after LPM.

Compare #AIX installed SW.
compare_report takes lslpp -Lc from 2x AIX LPARs and reports differences.
E.g. compare_report -b a.txt -o b.txt -h
