HP Serviceguard for Linux Version A.11.20.00 Deployment Guide, August 2012

Tip:
Do not connect the Fibre Channel cables to each server until after the OS
has been installed on each server, otherwise the OS installation process
may attempt to place the boot image on the external storage device.
Network Planning
The minimum network configuration requires two network connections (eth2 and eth3) configured as a
bonded pair running a heartbeat and the public network connections from each server. Each
network connection should be plugged into separate switches (see Figure 1). If three network
connections are used, one should be configured in a private heartbeat network (eth0, shown in grey
in Figure 1) and the other should be a bonded pair for the public and heartbeat networks. For more
details, see Managing HP Serviceguard for Linux manual.
