Odd issue I'm seeing:
We have an All-flash vSAN setup, which we've been running since 6.5 GA... We've upgraded everything to the latest patch releases, and are on vSAN 6.6... Everything was working fine, it looks like fairly recently (still trying to examine logs), all the disk groups now appear as Hybrid, instead of All-flash. So, not sure what is going on - we can't see/check deduplication anymore, as the monitor shows it's disabled.
Is there any way we can remark or reflag the disk groups as All-Flash?
Trying to see if anyone has encountered this before we open a support case.
