Are there any AIX 4.2 commands that would give me the ability to monitor the hardware temperature ?
I did a forum search and found nothing about AIX. I checked the 'diag' command but it does not say anywhere that it has this feature. I tried the 'prtdiag' command but it does not exist on the client's system.
Also there are some more listed below that one. Not sure if uesensor is available on 4.2. Else I would try to rely on monitoring errpt if something shows up.
That command depends on a hw sensor in the server actually. Such a sensor can be found in many Power3 systems but I don't remember a Power4 system having it. Hence it may well be that power servers are not being assembled with such sensors since. This is an example from a B80:
