hi expert
if i have 2 exchange server member of a DAG but the database on each of them is stored on a storage.
what happened if the primary server or active server lost connection to the storage? does it fail over to the second server member of the DAG?

Hi,

If this happens the information store can't write it's data anymore to the disk and will cause a failover to happen. Keep in mind that if you have 2 exchange servers you also need to implement a witness share to keep the quorum.

Regards,
Johan
