So i've been doing some lab work and i'm trying to observe its behavior during shutdown.
I have a two node DAG with a 1FSW,
I shutdown DAG member A and databases fail over to member B
I shutdown the FSW and member B databases stay mounted
finally i restart B and without the FSW the database won't mount.
So my questions are:
1) Why did restarting the member B (Member A and FSW were still offline) prevent Member B from mounting Databases
2) Why did turning off the FSW not break the DAG
3) Why would turning off the FSW while both Members are running break a DAG
Thanks in advance.
