xNBA 1.20.1 is almost identical to iPXE 1.20.1 with minimal customization.
I'm by no means a PXE expert : am I right assuming iPXE and/or xNBA use
some PXE firmware built in into some EEPROM on the nic or board ?
Are there any differences in the BIOS boot mode settings between the
servers that are working and the servers that are failing?
Legacy mode vs Legacy + UEFI mode vs UEFI only mode?
No. They both boot in full UEFI mode (no legacy, no dual). Some may have
a different version but the issue occurs across the same BIOS version too.
Do you have better results if you downgrade xNBA to the previous version?
I indeed manage to workaround the issue by savagely replacing xnba.efi
by the one I extracted from the 2.15 branch, which I believe was already
xnba-undi-1.0.3-131028.noarch.rpm
Supermicro provided me as well with:
- nic EEPROM new firmare (I did not use nor flash)
- new PXE firmware which I flashed: this made the new xNBA works as
expected.
They stated that:
Batch 1 was shipped with a different EEPROM and PXE option ROIM version
then Batch 2 and 3.
Batch one has FW 1.93 and PXE version 2.4.16 while batch 2 and 3 will
have FW 2.2 and PXE version 2.4.44
I still have to test flashing this new PXE fw to a batch2 node (which
worked with the new xNBA but spent >30s in it) and see if it fixes the
slow initialization.
Thanks
