set autoboot

[Leah Chow]

We had a power outage that occured last week. The power switched on and off several times, which damanged the servers.

I would like to set the autoboot off on my server. Once I do that, can I still use shutdown -ry 0 to boot the machine or do I have to use Console to boot the server?

Please help

Thanks
Leah

You can set thisoff, and a shutdown would stil work.
However, if the system were to power off and then on again, you would need to manually boot the server from the console
use setboot -b to turn it off/on without first shutting down the server.
man setboot

when your autoboot is off, its means you will come at BCH ( boot control handler)

when you come at BCH its means you need your console to boot your OS

Main Menu> Bo
interact with IPL : n

and your server will be boot.

using shutdown -ry 0 you can used it, but your system stop at BCH.

Use setboot by itself to see your current settings

Once you disable setboot, your system will stop at the BCH and wait for instructions before procedeeding with the boot.

Yes, shutdown -ry 0 will continue to work as in the past.

The parameter autoboot=off does what it means, it prevents the server from booting automatically and will stop at the boot menu.


Some of the servers have a possibility to set the "Power Restore Policy Config" in the MP/ILO.

Maybe this is what you are looking for.

MP:CM> PR

more info about the command:

PR: Power restore policy configuration
Use this command to configure the power restore policy. The power restore policy determines how the system
or chassis behaves when AC power returns after an AC power loss.
If PR is set to On, the system powers on after AC is applied. If PR is set to Off, the system stays powered off
after AC is applied. You must first push the system power switch or execute a PC command to power on the
system.
If PR is set to Previous, the power is restored to the state that was in effect when AC was removed or lost.
