If you talk about compatibility then ofcourse MSA2040 not compatible with ESX6.7 because HPE not yet tested this. So any behavior is unpredictable and there is no official support from HPE with this setup. You can get that details from SPOCK,
I am still interested to see NetApp is using what kind of technology where VMFS extend happens automatically. Do you have any document or link where it can be shown that after expand of LUN size in NetApp block level corresponding datastore VMFS extend happens automatically.
Hope this helps!
