AC power restore power on action, PowerEdge R630

Hi, thanks for choosing Dell. What AC power recovery does for you is , when the power abruptly shuts down then it resumes, it will automatically changes the last status (so if your last status was on, it will turn back to on after the power shut off). If the power supply was stopped from UPS, it’s possible that system power down procedure was a proper one. So again, check whether  your power is on or off. Hope this helps ^^

Thanks for your reply.  Is it possible to just have the server go back on automatically after power is restored?

Hello itnorm78,

The options should be: AC Power Recovery-- On, Off, Last

If you configure for On it should power on, regardless of last state, when power is restored.

I do not know a way to test it without shutting down.

Try testing this way:

You can power up and press F11 for boot menu, let it sit there,  pull power, wait a minute or so, reconnect power and check results.

Thanks for your reply.  I will give that a go.  The UPS is not connected to the server in a way to gracefully power down the server in the event of power loss and subsequent battery charge trickle down to zero.  There is an event in the Windows Event Viewer of "The previous system shutdown at 4:22:02 PM on ‎6/‎20/‎2021 was unexpected." which coincides with the loss of services on that server.

This is what puzzles me.  That omconfig command I posted earlier should have had the server powering up once power was restored.  Is there a way to verify in the bios that the server will power on after a power loss?

Hello itnorm78,

After you have configured the BIOS to ON, saved and exit BIOS, then test this way:

You can power up and press F11 for boot menu, let it sit there,  pull power, wait a minute or so, reconnect power and check results.

I did as you suggested.  I restarted into the boot manager by F11.  I waited.  I unplugged both power supplies and the server was powered down.  I waited.  Then I plugged in the PSUs and the server did NOT power on.  I have not changed any other settings since my last post.

Do you have any suggestions?

Does it look like it is saving the setting power the server back up? There shouldn't be very much involved with getting it to properly cycle. If it looks like the BIOS is properly saving the setting, you might consider testing it off the UPS. I wouldn't expect it to be a UPS issue, but I've still seen some weird things happen here and there when connected to one.

If it doesn't look like it's saving the setting, you could see if making the change through racadm commands makes any difference. You'd want to SSH to the iDRAC to do this, but I believe the commands below are what you'd need.

racadm set BIOS.SysSecurity.AcPwrRcvry On

racadm jobqueue create BIOS.Setup.1-1 

Thanks for your reply.

The UPS is not an issue since I unplugged the server directly at its power supplies.  I have not setup the iDrac.  Could that be a factor?  The iDrac says its ip is 0.0.0.0.

I still would like to know where in the BIOS I can find the setting for the power recovery action of the server.

Thanks for that reply.  I'll check that.  Are all the entire BIOS settings accessible thru OpenManage?

For the most part, yes. I think there may be a few things that OMSA can't configure, but you can make the vast majority of settings configurations within OMSA.

OMSA->Main System Chassis->BIOS->Setup->BIOS->System Security->AC Power Recovery Delay

So I can check on the Auto Recovery setting when power is restored thru OMSA?  (If so, then I don't need to restart the server.)

After we run the above command to change the setting to On:

racadm set BIOS.SysSecurity.AcPwrRcvry On

 
racadm jobqueue create BIOS.Setup.1-1

We would like to verify that the setting command above did in fact change the setting From Off or Last to On.

To verify this can we run the following command:

racadm set BIOS.SysSecurity.AcPwrRcvry 

Will it reply "On" if the ACPwrRecvy is in fact currently set to On?

If this is not the correct command, is there another command that we can run to accomplish the objective?
