V490 Failed To Boot After ALOM poweron
After issuing reboot command (and disconnected from PuTTY), server is not even rebooted because ping test is succesful. So I connect to ALOM and issue poweroff command. After a minute, I did poweron and get this message (only).

Code:
rsc> poweron
Are you sure you want to turn your system power on (Yes/No)?  yes

RSC Alert: Host System has Reset

But system is not even booting to OS (because ping failed). This is output of showenvironment.

Code:
rsc> showenvironment

go to console from the rsc card with "console" and have a look if the "ok" prompt is visible... if so, have a look at the output of "printenv". i think "auto-boot?" is set to "false".
now you can do a "boot" to boot your 490 or you do a "setenv auto-boot? true" and then a "reset-all" and have a look if the new settings work.

Unfortunately I can't test it at the moment because the server is up around an hour ago. I was just been informed by my higher technical guy that auto-boot = false and now he set auto-boot = yes. I guess this is step that I need to do next time (based on ur comment and his email to me).

Code:
rsc> console

Code:
ok printenv auto-boot?
auto-boot = false
ok setenv auto-boot? true
auto-boot = true
ok reset-all

Now I know that previously system is not starting up automatically after power-on / reset because auto-boot is set to false (and the system stops at OK prompt). Thank you for the insight. You're the best, man !

Be aware, some administrators set this to false for a reason.

For instance, if there is an issue in the middle of the night - and a host reboots automatically, you may not be aware that an event occurred. This can be more of a problem if there is a specific order that hosts need to be brought online for.

ie: Database server up, then application server up. Database server dies and reboots. Application server does not respond properly until it is rebooted. This could result in a loss of data.

there is an "reboot-on-error" option to be sure this don't happens!

I've not seen reboot-on-error behave consistently when there is an intermittent hardware error.

Old 09-26-2008
the "reboot-on-error" has nothing to do with an hardware error... this stops the mashine from rebooting if it wasn't shut down cleanly!
so, after a panic the mashine won't boot if "reboot-on-error" is set to false...
