solman_setup - Database hosts when connecting a managed system

Dear Experts,

our systems are running on Hana database. We have 2 or 3 servers per SID as we have configured HSR. When connecting newly installed systems to the Solution Manager, I observe very seldom behavior that defies any logic in the steps Assign Product and Assign Diagnostics Agent

Sometimes I only see one database host in the step Assign Product. This is usually due to missing SLD data and when I make sure all DB servers have correctly transferred SLD data, it is fixed and the servers are present there. However, when I see all DB servers correctly in this point, my expectation is to see them also in the step Assign Diagnostics Agent! However, I see all application servers and all DB servers very rarely in this point! It seems to be independent from the point Assign Product and I did not find anything specific, that makes DB Servers appear or disappear from the point Assign Diagnostics Agent!

Could you please kindly explain how this works and most importantly - provide me an answer what exactly do I have to do, in order to see the DB Servers also in the point Assign Diagnostics Agent.

Many thanks for your help and advice!

Dear Customer, 

You are correct that in order to view the DB servers in Managed System Configuration, the LMDB must have complete information about the DB, including the "Technical Instances" and "Hosts," unless it is a virtual type of DB. In certain cases, like ORACLE RAC, HANA SR, HANA MDC, etc., there are specific associations that control the behavior, such as SAP_IdenticalDatabaseSystem and SAP_DatabaseReplicationDependency and so on.

Dear Customer, could you please double check if the JAVA HANA was really sent to the DEV SLD? Please check it via the following trace /usr/sap/<SID>/HDB<nn>/<host>/trace/sldreg.log.
