I've been pulling my hair for the last few days trying to get a FCI working with SQL Server and MSDTC, no matter what I try I can't get the MSDTC role to get online.
I've followed the instructions here: https://www.ryanjadams.com/2018/07/sql-server-failover-cluster-instance-azure-msdtc/
Current setup:
- Domain joined servers (ADDS)
- Two CSV (one for SQL, one for DTC) running on S2D (2 data disks per server = 4 disks in total)
- Windows Server 2019 Datacenter with latest updates applied
- SQL Server 2016 SP2 and latest CU
- Standard IP's (one NIC per server) and a Standard load balancer for the VM's
- Cloud witness for quorum
- Static ip addresses for all servers and FCI (cluster and roles)
- Pre-staged DNS records allowing authenticated users to update the records
- Running install/configuration with domain admin account
- Created the FC using the ManagementPointNetworkType = Singleton
- Allowed DTC, COM+ Network Access, Network Discovery, File and Printer Sharing plus the SQL port in Firewall
- Configured DTC to allow all options and tested different auth levels
All other settings are made according to the video Ryan posted but as soon as I set the static ip for the DTC role the resource fails and I can't get it started.
Anyone know what I'm missing? Has anyone else successfully configured a similar setup in Azure?
