How to find the hardware uptime for IBM Power Systems Frames


We needed to find the hardware uptime for a particular POWER9 frame to determine how close we were to hitting this known POWER9 firmware bug.

We found we could calculate this by looking at the "Progress Indicator History" view in ASMI and looking at the date associated with RUNTIME/STANDBY and working out how many days had passed since the frame was powered up.



We also find this technote, which provides a small C program to calculate the "hardware platform uptime". Based on our tests (on AIX/VIOS) it works well.
