Title: Cisco UCS C - IPMI URL?
Post by: Dieselboy on October 30, 2019, 03:23:19 AM
I have a couple of UCS-C220 M5 servers. I want to configure "fencing" which is allowing the virtualisation system the ability to control the power of the compute host (power off/on/reboot). I have followed the Cisco guide to enable IPMIoLAN: https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c/sw/cli/config/guide/4_0/b_Cisco_UCS_C-Series_CLI_Configuration_Guide_40/b_Cisco_UCS_C-Series_CLI_Configuration_Guide_40_chapter_01011.html

But it does not tell you how to get the url for the IPMI access. The host has a single IP address for the CIMC management, so I am guessing it's this IP address /something. I have tried ip/ipmi but that does not work. ip/redfish does load an API page. So seems like the documentation is incomplete

This host is not managed by ucs central.

Any ideas?  :'(

Side note - I Was in Sri Lanka a few weeks ago. The local server guy there was unable to log into the BIOS with error "incorrect password". He can't remember changing the password and the one he set 18 months prior was no longer working.

Solution = using the redfish API, we were able to craft a POST command via curl and set an empty bios password. This was for a Lenovo server.

When I query on Cisco IMPI URL, Google sends me here. :problem?:

The next link was a document from 2011 that happened to mention IMPI and URL in two different locations.

So is this something you can call support for assistance with?

Well that produces some better search results... is that something you set up in the BMC GUI?

Yes - in the gui though it just has these options for IPMI:

1. enable / disable checkbox
2. dropdown menu for you to select the privilege role (admin / user / read-only)
3. encryption key - with a button "randomize" to generate a random key like: FD5030667BDA5BXXXXXXXX96564FA3CF3FF957

My problem is that I dont understand how to utilise the above. IPMI over LAN in my experience has used username and password. On the virtualisation platform (red hat virtualisation), when selecting IPMI it requires:

1. address
2. username
3. password
4. options field

Username is mandatory and I've tried using admin with the password being the encryption key but that fails.

Redfish is not yet supported although will be from version 4.4 and current version is 4.3.6 but I am not sure when 4.4 comes out or if it gets released without bugs.

So does the device still need to be told where to go to get IPMI information? If so, I'm thinking that's a support call for the infos.
