I'm trying to run SQL Server Failover cluster in Azure.

I have NODE1 and NODE2 in a cluster and another SERVER in the same network trying to connect to the database server using the instance from the cluster.

  • NODE1 can connect to cluster instance when NODE1 is the active node.

  • NODE2 can connect to cluster instance when NODE2 is the active node.

  • SERVER can connect to cluster instance if using NODE1 network name and NODE1 is the active node.

  • SERVER can connect to cluster instance if using NODE2 network name and NODE2 is the active node.

1434 udp and 1433 tcp are on in both nodes. SQL Browser is running, Portqry 1434 returns the SQL instances only if I use the nodes network name but not the cluster network name.

I've googled and tried everything you can imagine (disabled firewall, changed network card loop flags, used different ports, add endpoints in azure for a variety range of ports, etc...)

To make it short... I want to know if there's some sort of restriction in Azure that doesn't allow me to make this work.

  • I know nothing about this, but it sounds like a VIP address fails over to the active node – Philᵀᴹ May 27 '14 at 20:51
