During configuring SAP HANA replication you are getting the error:
Error while executing the register command: hdbnsutil -sr_register
Primary and secondary has different systemPKI SSFS data and key or unable to check; Secondary system PKI SSFS-data-file checksum is different from primary!
You just need to copy keys from the source system to the target:
su - <sidadm>
cdglo
scp security/rsecssfs/key/*.KEY $USER@<sap_db_host_name>:/usr/sap/$SAPSYSTEMNAME/SYS/global/security/rsecssfs/key/
scp security/rsecssfs/data/*.DAT $USER@<sap_db_host_name>:/usr/sap/$SAPSYSTEMNAME/SYS/global/security/rsecssfs/data/
