SAP HANA Server (SUSE) – Service Restart Procedure || Server Maintance


1. Login to the SAP HANA Server

  • Log in to the SUSE (HANA) server using root access.
  • Verify which user you are logged in as:

# who am i

Note: As a best practice, take a full backup of all databases before starting the following activity.

2. Stop All HANA Services

Run the following commands to stop all SAP HANA-related services:

  • systemctl stop sapb1servertools-authentication.service
  • systemctl stop authentication.service
  • systemctl stop sapb1edfbackend.service
  • systemctl stop b1s.service
  • systemctl stop sapb1servertools.service

3. Verify That Services Are Stopped

Check the status of each service:

# systemctl status sapb1servertools-authentication.service

The Active status should be inactive.

4. Login as NDB User

# su – ndbadm

5. Check the HDB Status

ndbadm@SAPSERVER:/usr/sap/NDB/HDB00> HDB info

If multiple services are shown as running, it means the HDB service is still active.

6. Stop the HDB

ndbadm@SAPSERVER:/usr/sap/NDB/HDB00> HDB stop

Note: Please wait until the process is fully stopped before proceeding. This may take 10 to 20 minutes, depending on the server configuration.

7. Verify That HDB Has Stopped Completely

ndbadm@SAPSERVER:/usr/sap/NDB/HDB00> HDB info

8. Reboot the SUSE (HANA) Server

# reboot

9. After Reboot – Login as Root

Once the server is up and running again, log in with root privileges.

10. Login as NDB User

# su – ndbadm

11. Start the HDB

ndbadm@HANA3:/usr/sap/NDB/HDB00> HDB start

12. Start the NDB Services

Run the following commands to start all related services:

  • systemctl start sapb1servertools-authentication.service
  • systemctl start authentication.service
  • systemctl start sapb1edfbackend.service
  • systemctl start b1s.service
  • systemctl start sapb1servertools.service

13. Verify That All Services Are Running

# systemctl status sapb1servertools-authentication.service

Ensure the Active status shows as active (running).

14. Final Step

Log in to SAP and verify that all functionalities are working correctly.
