Unable to update iLO3 firmware on HP BL465c G7 blades

We’ve recently needed to upgrade the OA firmware on our HP C7000 blade enclosures to support Gen8 blades. A pre-requisite is to first make sure the ROM/BIOS and iLO firmware is up to a certain level.

While attempting to upgrade iLO on the HP BL465c G7 blades, quite often i’d get an error upgrading from 1.16 and below up to 1.50. I’ve contacted HP about it and they refer to a support document detailing steps on how to perform steps to recover from a failed iLO update. These steps are quite involved and require downing a server, setting DIP switches on the motherboard, then getting to the command line in HP SUM and running a bunch of commands.

There’s an easier way. You’ll need to perform a stepped upgrade firstly to 1.28 and then to 1.50.

  1. Firstly get the ilo2_128.bin firmware from HP.
  2. Upload the firmware from the iLO Web Administration page.
  3. Once that is done I found I needed to clear the browsers cache before going back into iLO, otherwise the page didn’t render correctly.
  4. Once that is done, then complete the upgrade to 1.50.

I hope this helps. Please feel free to drop me a comment to let me know how you went!
