Delphix engine does not support availability group configurations where any replica of the AG (whether primary or secondary) is hosted on a SQL server failover cluster instance irrespective of values set for other properties like availability mode, failover mode etc.
Below is an example of such an unsupported configuration:
| Properties | Primary availability replica (PAR) | Secondary availability replica (SAR1) | Secondary availability replica (SAR2) |
|---|---|---|---|
| Server instance | Standalone instance (SI1) | Standalone instance (SI2) | Failover cluster instance (FCI) |
| Availability mode | Synchronous-commit | Synchronous-commit | Asynchronous-commit |
| Failover mode | Automatic | Automatic | Manual |
| Readable secondary | Yes/No | Yes/No | Yes/No |
