SUSE Linux Enterprise Server for SAP Applications 12 Service Pack 2

Situation

Following document "Operating System Security Hardening Guide for SAP HANA" (p18), a node has been configured with following settings:
        # ip a s
        ...
        18: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
        link/ether 14:02:ec:95:04:41 brd ff:ff:ff:ff:ff:ff
        inet 10.10.3.51/24 brd 10.10.3.255 scope global bond0
        inet 10.10.3.52/24 brd 10.10.3.255 scope global secondary bond0:hanaph1
        ...

        and /etc/sysconfig/hana-firewall is set as
        ...
        INTERFACE_0="bond0"
        INTERFACE_0_SERVICES="HANA_STUDIO_LIFECYCLE_MANAGER HANA_HTTP_CLIENT_ACCESS HANA_STUDIO HANA_DATABASE_CLIENT HANA_HIGH_AVAILABILITY HANA_SAP_SUPPORT HANA_SYSTEM_REPLICATION"
        INTERFACE_1="bond0:hanaph1"
        INTERFACE_1_SERVICES="HANA_STUDIO_LIFECYCLE_MANAGER HANA_HTTP_CLIENT_ACCESS HANA_STUDIO HANA_DATABASE_CLIENT HANA_SYSTEM_REPLICATION HANA_HIGH_AVAILABILITY HANA_DATA_PROVISIONING"
        ...

        However, when executing 'hana-firewall dry-run' the following error was observed instead:
        # hana-firewall dry-run
    ERROR: Interface bond0:hanaph1 doesn't exist on the system.

Resolution

This is due to the limitation on the NIC checking function used in hana-firewall script (HANA-Firewall-1.1.4-6.1). PTF was built and pending for confirmation. Customers encountering this issue should open a request with Technical Services to obtain a program Temporary Fix (PTF). Patch will be provided in future release.
