Re: [xcat-user] [External] nodeset and UEFI boot xnba files

[Christian C. <cca...@le...>]

If it changes to something like:

#!gpxe
#boot
Exit

... Then that is, to the best of my knowledge, the expected behavior when you run 'nodeset {node} boot'. Of course, you should not configure a stateless node as "boot" at all since it will always require a stateless image in response to a PXE request (after the initial boot kernel). Stateful nodes shouldn't get anything from a PXE request unless they're being (re)discovered or (re)installed. If they're "full UEFI," they shouldn't be sending a PXE request after they're installed as the OS would have inserted its own entry at the top of the boot order during install.

Subject: [External] [xcat-user] nodeset and UEFI boot xnba files

Hello,

I'm using xCAT 2.16.1 on CentOS 8.3.2011 to provision stateless and stateful CentOS 8.3 nodes booting in "full UEFI" mode (no DUAL nor Legacy mode).

This works fine but I noticed today that the tftp xnba .uefi file is not touched by nodeset

For instance, for a switch based discovered uefi booted stateless node foobar, xCAT generated the 2 following xnba files :

/tftpboot/xcat/xnba/nodes/foobar
/tftpboot/xcat/xnba/nodes/foobar.uefi

holding the usual imgfetch, imgload and so on commands

According to the generated lease file, I'd say that, for an UEFI boot, only /tftpboot/xcat/xnba/nodes/foobar.uefi is served:

} elsif option user-class-identifier = "xNBA" and option
                 client-architecture = 00:09 {
           supersede server.filename =
 
"http://x.x.x.x:80/tftpboot/xcat/xnba/nodes/foobar.uefi";

But I noticed that, either for stateful or stateless case, nodeset foobar boot (for instance) only modifies /tftpboot/xcat/xnba/nodes/foobar, which seems wrong to me ?

Can you help me figure out if this is an issue or if I'm missing something ?

Thanks for your help
