<br>
thanks for the reply. I am aware you can install user and admin level, erm, <br>
users on the BMC. I only install admin-level users as there is only a need for <br>
an admin to access the BMC GUI. <br>
However, that does not explain why the IP address is working and the hostname <br>
is not. <br>
<br>
The only way to get the users installed was using the ipmitool command once <br>
the node was up and running. I tried in the BIOS but that was not working. I <br>
got told you will need to enable the 'root' user first before you can install <br>
users but in the BIOS there was no option for that or we did not find it. <br>
<br>
I guess it is the usual learning initial curve here for me. I actually did <br>
look into the documentation but I could not find anything we were doing wrong <br>
at the time. Quite often I found it is a really minor, but important bit one <br>
is missing out and later you think: why did I miss that.<br>
<br>
Thanks for your suggestions!<br>
