Getting your backups working for the weekend is the right call.
If you do flip the replica from suspended to a forced shutdown, whatever you notice about the chain afterwards would be worth a line here.
That is the one question I could not answer, and I have not found it written down anywhere either.
On the logs, I would wait until someone from the storage side actually asks, so you are not gathering things nobody reads. The VM_BAD_POWER_STATE from post #3 is with @Team-Storage now, though I honestly do not know how fast that gets picked up.
Sorry again for the memory advice, and thanks for staying patient with a thread that changed direction twice on you.
