Recently we were flashing the firmware of few of our HP Proliant BL460c G9 blades.
One of the blades seemed to finish flashing the firmware (BIOS/Power Controller/iLO) and I went on to reboot it.
However when I tried to reboot it the blade never finished posting (it never got on to the second post screen).
The solution is very simple. Run the reset BIOS procedure (dip 6 on, blade power on, wait until you see messages on the screen saying you can turn the blade off, reset dip). Whola….the machine will finish the boot process 🙂
Also – during the firmware update process, don’t worry if the machine will reboot a couple of times after you reboot it when you have finished flashing…it is normal!
