Disabling SR of Node 2

Disabling SR of Node 2

  1. Log in to the secondary HANA node as the root user.
  2. Run the su - s00adm command to switch to the database user.

    s00adm is the database user name automatically generated during the database installation, and s00 is the database SID in lowercase. Change them based on the actual situation.

    hw00002:/ # su - s00adm

  3. Run the hdbnsutil -sr_disable command to disable SR.

    s00adm@hw00002:/usr/sap/S00/HDB00> hdbnsutil -sr_disable

    nameserver is running, proceeding ...

  4. Run the hdbnsutil -sr_state command to check the database system replication status on the secondary node.
