3245952 - SLT tries to connect to the secondary site of target HANA DB

In an SLT system, the target HANA DB is enabled with System Replication.
In the target HANA DB, you performed failover (takeover): primary -> secondary, after that, SLT starts to fail.
Later, you performed failback: secondary (original) -> primary (original), after that, SLT fails either.

In the work process trace, the same or similar error messages as below are observed.
It failed due to it tries to connect to <secondary IP>.

----------------------------------------------

In DBCO, you creates a new connection to primary site (primary IP). During the test, you observed it still try to connect to <secondary IP> and fails with the similar error:
Connection failed (RTE:[89006] System call 'send' failed, rc=32:Broken pipe {<secondary IP>:30053}
