RE: Leaving IBM i on vs. sleep mode and fire it up now and then

Not what you want to do. You are doing more of a controlled pull the plug from the wall that way.

You are always better off shutting the machine down normally. Which contrary to opinion is to bring the system to a restricted state from the console, AND THEN issue the PWRDWNSYS command. I always tell my customers only use the *IMMED when the building is on fire. You are better to let the system come after all the jobs are ended, that is why I always recommend ENDSBS *ALL (pick your time frame 30 or 60 seconds) before issuing the PWRDWNSYS command.

I must have read something wrong a few years ago. I've had in my head that it was doing some sort of suspend. You know how reading IBM docs is..
haha..

So, on my 515 (V5R4) holding the power button down for 5 seconds (while the display counts down) is the same as issuing PWRDWNSYS *IMMED? Seems that way. :)

Is there really such thing as sleep mode ?

It does exist for IBM i on Power Systems.
The name of this function is Partition Suspend and Resume. It was
provided by 7.1 TR2 and requires using VIOS.

When I did PWRDWNSYS on our old 515 the power supply the fans would
still

spin, but I didn't know there was a way to suspend via the white button.

I have v7r3 development box (power 8) that I leave on all the time.

My question is with my older 515 running V5R4. I normally put it to
sleep by holding the power button. Then when I need to do some work
on it I fire it up.

This is normally about 2-5x a month.

Would it be better for the 515 machine to just leave it running? Or
is the sleep/wake cycle not a huge issue with this hardware?
