Past two weeks I have been upgrading the iLO and ROM of all our servers (a bunch of HP DL 360s basically – Gen6 to Gen8) following which I upgrade them from ESXi 4.1 to 5.5. Side by side I have also been upgrading the iLO and ROM of our LeftHand/ StoreVirtual boxes following which I upgrade them from LeftHand OS 8.5 to 12.0. Yes, I’ve been busy!
Interesting thing about the firmware upgrades is that even between servers of the same model, when upgrading with the same Service Pack for Proliant (SPP) CD version, I get different errors. Some odd ones really. For instance some servers simply power off once the SPP CD boots, others give me a Pink Screen of Death, and yet others simply hang with the pulsating HP logo.
I couldn’t find any solutions for the servers that power off (I used SPP version 2015.04, 2014.09, 2014.06 and 2013.02 – same results for all). I was able to work around the pink screen by using an older version (for instance, I was using 2015.04 and that failed but 2014.09 worked). And I sorted of worked around the pulsating logo problem.
For the pulsating logo issue apparently the fix is to upgrade iLO first and then run the SPP. In my case the servers had really ancient versions of iLO – “1.87 06/03/2009” – so I upgraded them via the iLO webpage. The blog post I link to before (and also this one) show a way of updating iLO via SSH but that didn’t work for me sadly. (Could just be the web server I was running. I used TinyWeb to run a small web server off my desktop machine).
Before upgrading iLO via SSH or the webpage, you need to get iLO first. That should be easy but I had trouble getting it. For anyone else looking for the latest and greatest version of iLO 2 this HP page is what you want (and the “Revision History” tab on that page gives you older versions too). That page lets you download versions of the firmware for flashing via Linux or Windows. I downloaded the Windows versions, right clicked on it (it’s an EXE file) via 7-Zip (any other zip tool should do), and extracted the contents. The result is a file with a name like “ilo2_225.bin”. This is the binary image of the iLO 2 firmware that you can flash via SSH or the webpage.
Flashing via the webpage is easy. Go to the “Administration” tab, click Browse to select this file, and click “Send firmware image”.
Use a modern browser if you can. :-) I used the ancient version of IE on my server and that didn’t do anything, but when I used Firefox I was able to see a progress bar and the firmware actually got updated.
Another thing I learnt is that for the LeftHand/ StoreVirtual servers, simply upgrading the OS or patching it is enough to upgrade the ROM too. So I could have saved some time for myself with the LeftHand/ StoreVirtual servers by updating the iLO (as above) and upgrading the OS. No need to run the SPP.
On a related note, I had some servers with an “Internal Health LED failed” error even though everything seemed to be alright with them. Upgrading the iLO sorted that out!
And while on the topic of iLO I had some servers whose iLO was not responsive. I couldn’t ping the iLO IP address nor could I connect to it. I was able to fix some of those servers by completely powering off the server, removing the power cables, removing the iLO cable, waiting a few minutes, putting back the power cable and powering on the server, and once it has loaded the OS put in the iLO cable. (I have also read reports on the Internet where there was no need to remove/ re-insert the iLO cable so YMMV).
One server though had no luck – its iLO chip was faulty I guess. I tried to upgrade its iLO firmware and ROM by physically being in front of the server but it would hang at the pulsating logo as above. I think the faulty iLO was causing SPP to fail. Because of the faulty iLO though, ESXi would hang at “loading module ipmi_si_drv” for about 30 minutes each time it would boot (or when I’d run the installer to upgrade to 5.5). The solution is as detailed in this blog post. (Note: the argument is
noipmiEnabled – I was mistakenly typing
noipmiEnable the first few times and nothing happened). Post-install I configured the
VMkernel.Boot.impiEnabled advanced configuration option to 0 (I unchecked it). This way I don’t have to enter the boot options each time.
