HP-UX: Help to Change network configuration from APA manual mode (2Gbps) to simple fail over (1Gbps)
Hello HP-UX experts,

Server = rx8640 Node partition
OS = HP-UX 11.23
arch = IA64
Network switch = Foundry 16 port switch (1Gbps)

Existing configuration: Tough to explain as it is very messy (see below for the link of zip of network related fles). 2 x 2Gbps aggregates configured some time ago. But suddenly faced some packet loss issue and it was solved by disabling one of the ports (of aggregate) on one of the switch. There were two interfaces which formed lan900 however one cable was going to one switch and another to another switch. Networks team confirmed that both switches were seeing same MAC address and both were receiving packets at the same time hence disabling on of the network port on one of the switch resolved the packet loss issue. however now the server doesn't have any resilience and its running only on one network interface with 1gbps bandwidth. server also has a service guard package name dbXY0.

As it is noticed that 1Gbps throughput would be enough for the server, its decided NOT to use any aggregate instead a simple failover (2 NICs - 1Gbps each active/passive LAN_MONITOR mode). Could anyone please suggest me how to remove existing APA config and configure simple fail over (1Gbps throughput) using LAN_Monitor mode? I'm not entirely sure which Interfaces I need to deconfigure and which interfaces to configure for new setup as service guard config should not get affected.

Pl let me know if any more info needed from my end. Appreciate any professional help!

Thanks a lot.

Note: I'm unable to attach zip of various network commands' output - getting "invalid thread contact admin" error. So uploaded to dropbox, here is the link

systemd-networkd.service

SYSTEMD-NETWORKD.SERVICE(8)				     systemd-networkd.service				       SYSTEMD-NETWORKD.SERVICE(8)

NAME

       systemd-networkd.service, systemd-networkd - Network manager

SYNOPSIS

       systemd-networkd.service

       /lib/systemd/systemd-networkd

DESCRIPTION

       systemd-networkd is a system service that manages networks. It detects and configures network devices as they appear, as well as creating
       virtual network devices.

       To configure low-level link settings independently of networks, see systemd.link(5).

       systemd-networkd will create network devices based on the configuration in systemd.netdev(5) files, respecting the [Match] sections in
       those files.

       systemd-networkd will manage network addresses and routes for any link for which it finds a .network file with an appropriate [Match]
       section, see systemd.network(5). For those links, it will flush existing network addresses and routes when bringing up the device. Any
       links not matched by one of the .network files will be ignored. It is also possible to explicitly tell systemd-networkd to ignore a link by
       using Unmanaged=yes option, see systemd.network(5).

       When systemd-networkd exits, it generally leaves existing network devices and configuration intact. This makes it possible to transition
       from the initrams and to restart the service without breaking connectivity. This also means that when configuration is updated and
       systemd-networkd is restarted, netdev interfaces for which configuration was removed will not be dropped, and may need to be cleaned up
       manually.

CONFIGURATION FILES

       The configuration files are read from the files located in the system network directory /lib/systemd/network, the volatile runtime network
       directory /run/systemd/network and the local administration network directory /etc/systemd/network.

       Networks are configured in .network files, see systemd.network(5), and virtual network devices are configured in .netdev files, see
       systemd.netdev(5).
