Installing EMS Hardware Monitors
The EMS Hardware Monitors software is distributed with the Support Tools (diagnostics). All the necessary
files for hardware monitoring are installed automatically when the Support Tools are installed. There are
several different ways that the Support Tools are installed:
• The Support Plus Media: installing the OnlineDiag depot from the Support Plus Media using swinstall.
• HP Software Depot website: downloading the “Support Tools for the HP 9000” in the “Enhancement
Releases” product category, then using swinstall to install the OnlineDiag depot.
• Automatic: with HP-UX 11i, the Support Tools are automatically installed from the OE CD-ROM when
the operating system is installed.
Complete instructions for installing STM are contained in Chapter 5 of the Support Plus: Diagnostics User's
Guide.
The following software components are installed for hardware monitoring:
• All hardware event monitors
• Monitor configuration files
• Monitoring Request Manager
• EMS framework, including the EMS graphical interface
All EMS Hardware Monitors on the CD-ROM will be installed on your system, but only those that support
hardware resources you are using will be active. If you add a new hardware resource to your system that uses
an installed monitor, the monitor will be launched when the system is restarted or following the execution of
the IOSCAN utility (which performs a real/hard ioscan).
NOTE Reinstalling or upgrading the STM software will erase the current PSM configuration. Any
MC/ServiceGuard package dependencies or EMS monitoring requests you have created with
the PSM will be lost. Before reinstalling the STM software, record the current PSM
configuration so you can easily recreate it after the software has been installed. Or you can
comment out the PSM dependencies in the ServiceGuard configuration files, then re-enable
them after the STM software has been installed.
IOSCAN Utility
When you execute the IOSCAN utility, a “real/hard” ioscan is performed. The utility performs a scan of your
system hardware, gathering the most-current information.
Conversely, ‘ioscan -k’ is used by hardware monitors and diagnostics to obtain their information about
configured devices. The data returned by ‘ioscan -k’ is only as accurate as the last system reboot, or when a
“real/hard” ioscan is executed. This means that if a device or component is added to / removed from the
system, a “real/hard” ioscan should be executed in order to ensure an updated IOSCAN table in the kernel for
use by the hardware monitors and diagnostics. Otherwise, the hardware monitors and diagnostics will
operate on a stale, inaccurate picture of the system’s configuration.
Supported System Configuration
To use the hardware event monitors, your system must meet the following requirements:
