Whilst working on a bare-metal build for a Hyper-V host (based on HP blades with iLO 3) today using SCVMM 2012 and Host Profiles I came across the following error;
An out of band operation (IPMI) for the BMC <FQDN> failed
The obvious first line of troubleshooting is to check the IP address of the iLO connection was working (and that we had typed it right). This checked out, so the next check was to make sure the account we are using to access iLO has the necessary permissions to the host, and to check that IPMI commands are being accepted by iLO. This checked out as well and left us stumped!
After some further troubleshooting, we decided to re-create the account we had access to in iLO. We were not using the default ‘Administrator’ account, rather another delegated account that had been created for us.
We deleted this account, and re-created it using the same username/password to be greeted with an error along the lines of the username we are selecting has over 16 characters and therefore cannot be used to send IPMI commands….. however can still be created…..hmmm!
So let’s try shortening the account name, which we did, then changed the run-as account in SCVMM, re-ran the job and as if by magic our hosts started to boot 🙂
