Modifying OS Configurations

To ensure the proper installation of the SAP HANA system, disable the OS firewalls of all nodes before the installation.

Procedure

  1. Log in to the NAT server as user root using the key file. Then, use SSH to switch to SAP HANA nodes.
  2. Run the following commands on the SAP HANA node to disable automatic firewall enabling and disable the firewall:

    If the OS is SUSE Linux Enterprise Server 11 SP4, run the following commands:

    chkconfig SuSEfirewall2_setup off

    chkconfig SuSEfirewall2_init off

    SuSEfirewall2 stop

    If the OS is SUSE Linux Enterprise Server 12, run the following commands:

    SuSEfirewall2 off

    SuSEfirewall2 stop

    systemctl disable SuSEfirewall2_init.service

    systemctl disable SuSEfirewall2.service

    systemctl stop SuSEfirewall2_init.service

    systemctl stop SuSEfirewall2.service

  3. Repeat the preceding step to disable the firewalls of all nodes in the SAP HANA system.
