Hey all,

I am trying to pull in some AIX servers using NCPA via the wizard, and 18 of the 130 I have done are having issues. They don't see the mount points, the processes, etc. They are all on the same OS level, have the same patches, etc.

This is the error.

I've compared a server that has no issues to the others and I don't see what is wrong. Any help would be appreciated.

This seems to be an issue with the psutils python library. Do you have any special permissions set up on any of your servers?

What version of NCPA are you using? It's possible that the version you're using has an older version of the psutil library and is missing some fixes for things like this. NCPA 3.0.1 just released with the latest version of the psutil library and may fix your problems.

The configs and versions of python are the same on the servers. And the latests, and from what I understand is the last version of ncpa for AIX, is ncpa-2.2.1.aix7.1.ppc.

I tried uninstalling ncpa and reinstalling it but that did not fix the issue. This is very weird. Could it be because XI is 2024R1?
