We just updated our engine to 4.3, but when I tried to update one of our
AMD EPYC hosts it could not activate with the error:
Host vmc2h2 moved to Non-Operational state as host CPU type is not
supported in this cluster compatibility version or is not supported at all.
Relevant (I think) parts from the the engine log:
(EE-ManagedThreadFactory-engineScheduled-Thread-82) [ee51a70] Could not

I also tried creating a new 4.3 cluster, set to the AMD EPYC IPBDB SSBD and
moving the host into it, but it failed to move it into that cluster with a
similar error about an unsupported CPU (for some reason it also made me
clear the additional kernel options as well, we use 1gb hugepages). I have
not yet tried removing the host entirely and adding it as part of creating
the new cluster.
We have been/are using a database change to update the 4.2 cluster level to
include EPYC support with the following entries (can post the whole query
if needed):
7:AMD EPYC:svm,nx,model_EPYC:EPYC:x86_64; 8:AMD EPYC
IBPB:svm,nx,ibpb,model_EPYC:EPYC-IBPB:x86_64
We have been running 4.2 with this for awhile. We did apply the same
changes after the 4.3 update, but only for the 4.2 cluster level. We only
used the AMD EPYC IBPB model.
Reverting the host back to 4.2 allows it to activate and run normally.
Anyone have any ideas as to why it can't seem to find the cpu type?
Thanks,
Ryan Bullock
