Hi,
I've SQL 2019 STD with CU16 on Win 2019 STD. i had some ESXI host unresponsive for 5 sec and the SQL AlwaysOn become completely malfunction that both my SQL Server the databases that are part of the AlwaysOn are i the state of restoring. the "funny" thing is that the AlwaysOn configuration completely disappear from both server. there was nothing in those DMV sys.dm_hadr_availability_group_states ,sys.availability_groups ,sys.availability_groups_cluster,sys.dm_hadr_availability_replica_states ,sys.availability_replicas ,sys.dm_hadr_availability_replica_cluster_states .
how this can be happened?
