The HANA database would have a ID such as ABC. In that case use following steps to check database replication status

  1. Login into both primary and secondary servers as root
  2. Connect to DB admin account on both machines using
    su - <abc>adm
    where <abc> should be replaced with HANA DB ID
  3. Check whether database is running using:
    HDB info
    sapcontrol -nr 00
    We can get more help via 'sapcontrol -h'
    'HDB start' is used to start the DB and 'HDB stop' is used to stop the DB. These internally call sapcontrol appropriately to start/stop DB. See https://blogs.sap.com/2017/11/28/sap-hana-under-the-hood-hdb-by-the-sap-hana-academy/
  4. First we can check which machine is primary and which is secondary via:
    hdbnsutil -sr_state
  5. Then check replication status using:
    cd /usr/sap/<ABC>/HDB10/exe/python_support
    python systemReplicationStatus.py
    where <ABC> should be replaced with HANA DB ID
