How to kill a c-class blade

Filed under: Uncategorized — ermac318 @ 1:56 pm


So yesterday I decided to run firmware updates on a BL480c blade from HP that I was going to start using here in the lab. Four of five things needed updating, including the iLO processor.

Unfortunately, during the flash of iLO, something went wrong. I’m not really sure what, but the system never really came back… As soon as the flash failed, the fans in the blade chassis started running full bore, and the Onboard Administrator listed the system as having a failed management processor. So I powered it off and reseated it… And then it would never turn back on.

Word of warning – if you’re going to be flashing the iLO, do it from the dongle on the front of the blade, just to be safe. It just might save you a service call to HP and a motherboard replacement. Which, full disclosure, was done as of this morning with no fuss from HP.



  1. Justin, I actually came across your blog – GREAT STUFF! I work for a University and would like to pick your brain a little about storage requirements for VMware View. I tried inviting you to my LinkedIn network, but I don’t have your email/etc. Any chance I could ask you a few questions? I’m looking for quotes to deploy VMware View in my labs. Sorry to comment on your blog like this, I couldn’t figure out another way to get a hold of you! 😛

  2. Scott, Any advice about storage requirements would be extremely implementation specific. If you’re using View Composer, estimate about 90% storage savings is the ballpark number.

  3. ermac318, right, we would be using View Composer and linked clones. I’m not not so concerned about the amount of space, but trying to figure out number of spindles, speed, etc. I’m getting quotes for 48x15K SAS drives vs Sun storage with SSDs and SATA drives. Not thinking about storage amounts, what would you think ~200+ view clients would need for storage system?

  4. flashing the ilo from media mounted via the ilo is a no no….. It NEVER works and results in dead blades.

    Your best to use the ilo*.bin file and do the update from the ilo web interface. You can get this bin file from the online windows flash exe. Just extract the exe and there is the bin file to use.

  5. There’s a couple of options to prevent this happening. First off (and my favorite) use the OA cli and ILO firmware update all command. Second use Version Control Agent in HPSIM.HPSIM is free and this functionality is free.

  6. Today, I killed a BL480c using firmware maintenance CD.
    Are there any alternate solutions except HP support?
    Solutions like flashing the chip with serial port or …?
