I can't think of any xCAT features that would enable this behavior automatically.

The reason where I can’t use the default hostname (seated on the Mgmt net) is that network is not routed/allowed for security purpose. I’m just trying to know if there is another way to do that instead of doing it within a postscript session at the end of node provisioning. Thanks for any hints/advices.

I’m currently using the 2.16.3 version of xCAT on top of rhel 7.9 On my lab I have the following conf regarding the network topic: * Management network (not routed) – used for compute registration and installation * Public network (routed ) – network services (DNS, NTP , …) and public access On compute nodes we have the following Nics , let say : eno1 => management net (installnic) and eno2 => Public net During the node registration the node name (binded to the @IP of eno1) will be the default hostname, in my case node1-adm. But what I want to do is to replace the default hostname (normally on the management net) by using the @IP of the second NIC (eno2) on the public net I would like to have something like that : node1.mydomain.lab.fr as the hostname I’m thinking to run a postscript file at the end of the node installation by calling the relevant command (hostnamectl or modifying the /etc/hostname file). The question is: * During the node registration, do we have a way to setup the hostname as mentioned above, I mean that I would like to have the hostname binded to the NIC on the public network? Thanks in advance for any hints or direction I should take in order to achieve this setup.
