Description

Motivation

I was informed by hhoron and msuchanek that haldir+legolas are actually Pre-GA Power9 machines. That could be the reason why the machine ID, e.g. 8375-42A, looks like Power8 and racktables has it as Power8 but it's actually Power9 as can be seen in https://powerhmc1.oqa.prg2.suse.org when you click on the little (i) and see the firmware version. Or check CPU type from within an LPAR. We need to clarify that in racktables and correct workerconf.sls entries which has cpu-power8 worker classes which should be cpu-power9 instead.

Acceptance criteria

  • AC1: racktables entries make it clear that the mentioned machines are Power9
  • AC2: workerconf.sls has the correct cpu-power9 entries

So a web research for the type name "IBM Power System POWER8 S824 (8375-42A)" only reveals that it would be "Power8" so I will keep the racktables type, just added a description. I logged in over ssh to powerhmc and attached to one partition with mkvterm -m haldir -p haldir-1. The system was in a state unknown to me, something about "macro commands". I called RESET_PARTITION and when a message about "grub" showed up I clicked buttons and tried all boot options (leap/tumbleweed/…) until I saw the kernel boot output seeing

Hardware name: IBM,8375-42A POWER9 (raw) 0x4e0202 0xf000005 of:IBM,FW950.00 (VL950_045) hv:phyp pSeries

so Linux detects the system as "Power9". The kernel soon ended in a panic as it is unable to mount a root fs but the above is enough information anyway.

I also set the according information in powerhmc for both systems.
