??? Why are you doing this? Don't do this. Just do a "shutdown" at the
OS level - which will power off the server on 99.44% of hardware. Then
power-on using IPMI.

Not to mention that your task possibly didn't finish.

Yes. What you are doing is bad and wrong.
"shutdown -h now" will give you an immediate shutdown and power-off the
box. You can also schedule shutdown via shutdown, see "man shutdown".
