Fwiw, we were unaware of this becaise even the latest broadwell Lenovo servers work fine with the x710 nic. Best guess it is due to a particular interesting behavior of some uefi implementations, tolerated in elilo 3.16 but not 3.14. Now this is a guess since I only have servers that do not exhibit the problem. Applying our elilo patch against 3.16 may help. I can try that but someone else may beat me to it (writing from my phone..). There is a patch we wrote to enable ipxe protocol and get some useful variable substitutions to apply.
Longer term plan is to use the efi stub feature of Linux to obviate need for any second stage bootloader. For older kernels, we have a challenge. Elilo+ipxe remains the only way currently (as far as I know) to implement HTTPS boot, which a few users use (grub architecture isn't geared towards using high level uefi protocols, so it elects to reinvent everything inside it's own codebase, making ability to use ipxe network stack a challenge with that). When the transition happens, I need to double check.), but I want to say rhel7 and newer, Ubuntu 12.04 and newer, and sles11sp3 and newer would work with that strategy. Of course the bios style boot would still be viable for other editions. If it weren't for rhel6, I'd be more comfortable.... Note in the further flung future we may not even need ipxe (uefi 2.5 provides some interesting capabilities, but probably not going to see mainstream adoption until 2017 On Aug 28, 2015 6:13 AM, John Keenleyside <[email protected]> wrote: I am trying to use xCAT 2.9 to install Ubuntu 14.04.3 on a Supermicro TwinPro server with Intel x710-DA2 NICs. The install network is 10Gbps. We had to enable UEFI to enable boot from the x710 NICs. The kernel and initrd image are transferred successfully from the tftpboot directory on the xCAT server. However, an elilo error occurs immediately when the kernel is booted. Please see the attached picture that shows the elilo error. Has anyone seen this type of error? Any suggestions on how to fix this would be most appreciated. Also, I have observed that the elilo xCAT RPM is a few years old and that the elilo sourceforge project has been abandoned last year. Is there anyone that can comment on how xCAT can be used to install Linux on servers with new motherboards and NICs ? Thank you, John Keenleyside IBM
