It should be rather simple to patch the deploy code not fail on
missing vendor_id, it's used only for reporting. But it might not be
required, for now. You can try instead something like:
hosted-engine --deploy
--otopi-environment=OVEHOSTED_STORAGE/LunID=str:19eadf533875920f-46da4fac00000000
I didn't try this, not sure it would be enough. If it's not, you might
check the generated answer file from an old successful run and copy
and edit some more relevant lines (those with OVEHOSTED_STORAGE), put
in an answer file, and pass it with --config-append=answerfile.

No, the code checking vendor_id didn't change for at least 3 years.
Do you still have setup logs of successful deployments with this
storage (or as similar as possible)? Can you check them? Search for
otopi_fc_devices?
It sounds either as some change on the storage side (does not report
vendor id anymore) or on the engine/sdk/ansible-module/whatever (not
passing it anymore).
Nikolai, did you test FC HE deploy? Can you check logs?
Thanks and best regards,
