Hi , I am Setting up HANA Multitarget System Replication Setup. 2 Nodes at Primary site running on Redhat cluster and further 2 nodes running at DR site ( both is different Cluster ) .primary system A in data center 1 replicates data changes to secondary system B in the same data center. Primary system A also replicates data changes to secondary system C in data center 2. Secondary system C is a source system for a further secondary system D located in the same data center with system C.
i am following the below procedure provided by SAP notes.
Example: Configure a SAP HANA Multitarget System Replication - SAP Help Portal
any one implemented this solution, My system D is not able to Register with system C. Seems like System D is unable to find active system at C since it is registered as secondary of system B.
Any guidance will be much appreciated.
Thanks in Advance
Hello Ravindra,
You can use below command to configure your setup.
To register SITE3 as secondary of SITE1, follow below instructions:
SITE3> HDB stop
SITE3> hdbnsutil -sr_register --remoteHost=SITE1 --remoteInstance=03 --replicationMode=async --name=S3 --operationMode=logreplay
SITE3> HDB start
SITE3> hdbnsutil -sr_enable --name=S3
To register SITE4 as secondary of SITE3, follow below instructions:
SITE4> HDB stop
SITE4> hdbnsutil -sr_register --remoteHost=SITE3 --remoteInstance=03 --replicationMode=sync --name=S4 --operationMode=logreplay
SITE4> HDB start
