I have a basic question if we issue a power-off to a device does it goes in runlevel 0 ?
As far as I understand when a power-off is issued runlevel changes from 3 to 0 accordingly the /etc/init.d/halt script gets called.
This halt file is executed by init when it goes into runlevel 0 (halt) or runlevel 6 (reboot). It kills all processes, unmounts file systems and then either halts or reboots.
In my case the blade gets powered off without executing the halt script.
The issue was with packageMapping.list we had failed to pacakge a rpm which had a binary named hpmcmd which was responsible to issue a reset as this binary was missing so the reset command failed resulting system going for halt.
