Ensure that a composite group similar to HANA_CG is created on the management server at the remote site.
Run the following command to display the composite group details:
symrdf –cg HANA_CG query
symrdf –cg HANA_CG establish
To verify the status of the synchronization, run:
symrdf –cg HANA_CG query
After the values for R2 Inv Tracks are close to zero, go to the next step.
symrdf –cg HANA_CG set mode sync
symrdf –cg HANA_CG set mode async
To verify the new status of the SRDF pairs, run:
symrdf –cg HANA_CG query
symcg –cg HANA_CG enable
To ensure the consistency of the SRDF pairs, run:
symrdf –cg HANA_CG query
Note: DSE is enabled by default and is configurable as a percentage of the total SRP.
