Managing Serviceguard Eighteenth Edition, September 2010

provide as many separate power circuits as needed to prevent a single point of failure
of your nodes, disks and disk mirrors. Each power circuit should be protected by an
uninterruptible power source. For more details, refer to the section on “Power Supply
Planning” in Chapter 4, “Planning and Documenting an HA Cluster.”
Serviceguard is designed to work in conjunction with other high availability products,
such as:
• Mirrordisk/UX or Veritas Volume Manager, which provide disk redundancy to
eliminate single points of failure in the disk subsystem;
• Event Monitoring Service (EMS), which lets you monitor and detect failures that
are not directly handled by Serviceguard;
• disk arrays, which use various RAID levels for data protection;
• HP-supported uninterruptible power supplies (UPS), such as HP PowerTrust,
which eliminates failures related to power outage.
HP recommends these products; in conjunction with Serviceguard they provide the
highest degree of availability.

Serviceguard Manager is the graphical user interface for Serviceguard. It is available
as a “plug-in” to the System Management Homepage (SMH). SMH is a web-based
graphical user interface (GUI) that replaces SAM as the system administration GUI as
of HP-UX 11i v3 (but you can still run the SAM terminal interface; see “Using SAM”
(page 33)).
