since ppc64le support is only introduced in 3.6 we plan to only support a 3.6 compatibility level. There's no point to support anything lower than that as there is no earlier vdsms and 3.4/3.5 ppc64 is not compatible either
How this bug should be verified please?
you shouldn't be able to run in 3.5 compatibility level for ppc64le clusters, only 3.6
Verified with these flows:
1. Adding a new rhel 7.2 based ppc host to a datacenter/cluster 3.5 compatibility level for ppc64le fail during installation with these events:
Host host_mixed_1 is compatible with versions (3.6) and cannot join Cluster ilanit which is set to version 3.5.
Host host_mixed_1 moved to Non-Operational state as host CPU type is not supported in this cluster compatibility version or is not supported at all
2. Trying to change rhel 7.2 based ppc host cluster from 3.6 ppc cluster to 3.5 ppc cluster fail on:
Error while executing action:
Host CPU type is not supported in this cluster compatibility version or is not supported at all.
It is though possible to add a 3.5 compatibility level for ppc64le clusters.
