Thanks Nawals!
lab is a 4 Nodes cluster VSAN 6.7, I followed the 6.7 shutdown method before and did not notice issue.
When I read up on VSAN 7 steps, it include steps to off DRS and HA, which puzzle me. When I tried to off DRS, it wouldn't allow it without deleting first. (don't have a VSAN 7 lab)
If I understood you correctly, switch DRS to manual and there is no requirement to off DRS. Then the question, is it required for 6.7, since it is not stated in the steps as required to make any change to the DRS (and HA).
other questions are; (and ALL readers)
1. why vSphere 7 (VSAN) and v6.7 steps are difference? Why the next version required more steps?
2. For vSphere 7, does it mean we can off DRS without deleting the vAPP first.. (or switching to manual). What is the experience while doing this on a VSAN 7?
3. What is the impact using vSphere 6.7 steps (I would make this type of mistake) on a vSphere 7 system?
THANKS!
