Multi Subnet Failover availability for SCOM 2019
SCOM 2019 with OpsDB on AllwaysOn SQL Server is not Multi Subnet capable. Both nodes of the AllwaysOn server are located in different data centers. If the AllwaysOn failover to the passive node for whatever reason, SCOM loses the connection. He must ask the DNS server until it returns the active node behind the listener name. Unfortunately, this can take longer and the SCOM console does not work during this time. Very ugly! We are in the process of setting up a load balancer from F5 so that the SCOM server receives the response which is the active node behind the listener faster.
