I ran into this today.  I followed your document but I could not login with the username and password created in step 2.  I found another document that had two potential default passwords for the CIMC login.  I used 'password' to login to the CIMC.  It then prompted me to change it after successfully logging in.

Hello,

I followed the instructions in the PDF and am not able to get the workaround to work.

After completing the steps, rebooting and looking, the 5520s are still missing the MICs.

>show certificate all

--------------- Verification Certificates ---------------

-------------- Identification Certificates --------------

Interesting find. I did this to both 5520s. After looking at what is the standby 5520 it did not have the Hypervisor box checked. I checked it, rebooted, and now have certificates galore on my 5520s.

So even if you do it appears to be done on both, double check as I did and if one of the two in the HA pair is missing the Hypervisor checkbox you won't have certificates listed in the CLI.

Nice find on this. I had the same issue and the fix worked for me as well. Just so other people don't have to hunt it down, the default username/password to access that UI is admin/password

Hi, and thank you Jeffrey for the document.

Here is a short story how this went on my controller. It did not quite follow Jeffrey's instructions.

First I did not manage to access the controller with https. After the image failed to write to the flash because of signature failure many times with http, tftp and ftp I started to find bugs and found this Discussion.

In my controller's imm the "Host Accessible" was first in state "not-Connected". I anyway enabled the check box and clicked save. Web browser lost the connection. I checked the certificates. Every certificate that was previously in some state was lost. I shut down completely the controller - took the power cord even away, powered the system and started the procedure from the cli again - "imm restart". When I went to IMM again and clicked the save button the not-Connected changed to connected and after "system reset" the certificates was fully functional.

Just wondering if this problem was encountered from an out of box 5520 or during a code upgrade?  Could this also be related to cimc firmware upgrade?  Thanks in advance.
