Dhcp filename option for pxeboot of Power PC architecture

Daniele_Gregori_E4 · August 30, 2017, 3:32pm

Hi all,
I have some IBM Power PC 8 server to install but I cannot find a way to set the dhcp option:

filename=core.elf

In dhcp lease file to perform the correct pxe installation.
What I have to change in the PXE template? Is there a variable to set to define the “filename” ?
Or there is a best practice to install PPC with Foreman?

Thank you.

Daniele

Hello,

with recent versions of Foreman (1.14+) you set PXELoader to Grub2 EFI
and then the filename will be grubppc64le.efi or grubppc64.efi
depending on endian.

Note the incorrect extension (PPC is not EFI compatible), we are
tracking this under Bug #16706: Rename POWER DHCP filenames to elf - Foreman and we
will rename this properly according to grub2-mknetdir:
Bug #20815: Ship regexp.mod in foreman-bootloaders - Foreman

So for you at the moment is best to create a (relative) symlink named
grubppc64.efi -> path/to/your/core.elf

Hi Lukas,
I followed your instructions, first I did the symbolic link with:

[root@srv-install grub2]#pwd
/var/lib/tftpboot/grub2
[root@srv-install grub2]# ln -s /var/lib/tftpboot/core.elf grubppc64le.efi

And I changed also the PXE GRUB2 UEFI template in the operating system tab then I checked also the dhcpd.lease and there is the right filename:

host davide13.e4srv {
dynamic;
hardware ethernet 70:e2:84:14:1c:13;
fixed-address 172.16.2.207;
supersede server.filename = "grub2/grubppc64le.efi";
supersede server.next-server = ac:10:02:02;
supersede host-name = "davide13.e4srv";
}

When I boot the system I receive this error message:

Is in the directory:

The name and the location differs from the name/location find by the system.
Last but not least my Foreman version is 1.15.2.

Any hints?

Thank you

Is this non-Red Hat OS? I mean the system that serves the DHCP/TFTP?

> [root@srv-install grub2]# ln -s /var/lib/tftpboot/core.elf grubppc64le.efi

TFTP runs in chroot, never do absolute symlinks, only relative. Not
sure if this is same for non-RH OS tho.

This is weird, the path should be /grub2.

Where this core.elf comes from? Can you try grubppc64le.efi from
foreman-bootloaders package? We don't yet have debian packages, you
can just unpack upstream tarball here:

http://downloads.theforeman.org/foreman-bootloaders/

If that fails, try to build core.elf. yourself with grub2-mkimage:

Hi Lukas,
The system composed by Foreman (tftp) server and Power PC client is centos 7.
I take the Foreman bootloader and move the grubppc64le.efi to the /var/lib/tftpboot/grub2 directory with the same result, from /var/log/messages:

First of all, is your PPC CLIENT big or little endian? I see it is
trying to load little endian which is I believe less common to have.

Anyway, let's rule out Foreman completely, can you setup DHCP and TFTP
using our official documentation? Including generating tftpboot
directory structure via grub2-mknetdir, make sure to use the target
platform with correct endian, then scp the files onto TFTP server,
setup DHCP and try then:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/chap-installation-server-setup.html#sect-network-boot-setup-ppc-grub2

The filename should be set correctly to
"boot/grub2/powerpc-ieee1275/core.elf" now. Does it load from correct
paths now?

I have built the core.elf from RHEL 7.4, can you try that as well?
http://people.redhat.com/~lzapleta/test/grub2-ppc-test.tar.xz

Let's find out that first.

Danielle,

I've talked to our Grub2/PXE/BOOTP/POWER experts, can you get us:

dhcpd.conf
grub.conf
network comm dump (wireshark or similar)

Thanks

Few more questions:

What kind of POWER hardware is it? Some POWER machines have network
cards with Petitboot firmware which is capable of downloading
configuration in PXELinux syntax and then directly loading the kernel.
In this case, you need to provide your own PXELinux configuration (you
can use foreman templating capabilities to generate the contents of
course), but we don't have any templates with this - not sure if
default PXELinux templates will work, I guess they will not (kernel
and initramdisk).

More info here:

http://jk.ozlabs.org/blog/post/158/netbooting-petitboot/

If this is the case, I think you want to create your host in Foreman
with PXELinux BIOS flag and it will have filename option "pxelinux.0"
which should be ignored by petitboot and then it will try to load the
configuration from standard paths.
