coincide with support contracts on hardware if desired. This solution also includes support for Red
Hat, 3-year Red Hat Enterprise Linux Advanced Platform 24x7 either 1 to 2 sockets or unlimited
sockets depending upon the server chosen (visit http://www.hp.com/go/proliantrhel for more
information). Please note that support is highly recommended for all high availability solutions.
For Linux management to complement the SGLX capabilities in multi-system environments, HP's Insight
Control Environment for Linux (ICE-Linux) solution provides an integrated solution for system discovery,
deployment & imaging, monitoring, and management. HP ICE-Linux auto-configures Nagios and
other open source software to allow you to be quickly productive with Linux management, while still
preserving flexibility and extensibility. Nagios is a popular open source computer system and network
monitoring application software, which watches hosts and services, alerts users when things go wrong
and again when they get better.
For more details on the various support options available from HP and ICE-Linux, please consult with
your HP Sales Representative or Partner.
Getting Started
Hardware setup and networking planning must be completed before you start the installation.
Hardware Setup
The 2 servers and external storage device must be cabled for power, network, and storage
connectivity. For initial set-up of the MSA2000 storage device, a serial console device will be
needed. This can be done on a Windows laptop using the HyperTerminal software or with another
system running similar terminal software along with the Mini DB9 RS232 Serial cable supplied with
the MSA2000. A keyboard, mouse, and monitor will be required for use as a console to install the
operating system on each of the servers. 5 Ethernet cables are required (two for each server and one
for the storage device) along with access to 2 network switches (see Figure 1). Storage cabling is
described in “Connecting the MSA2000 to the servers” and illustrated in Figure 2. Four Fibre
Channel cables are required to connect the storage device to the servers.
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 2 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. The
manual “Managing HP Serviceguard for Linux” goes into more detail.
