What’s in This Version

The A.04.10 version of EMS for HP-UX 11i v2 operating system runs on PA-RISC and

Itanium 2-based platforms. The following changes have been made in this version:

• The registrar, EMS client, and monitor API (libresmon) can work with IPv6-enabled

systems using the IPv6 address.

• 64-bit EMS native libraries are available.

• EMS libraries are also shipped as PA-RISC binaries on HP-UX 11i v2 Intel Architecture

system to provide compatibility for the existing PA-RISC based monitors to run via Aries

Emulator.

EMS contains the following components:

• EMS Framework - The EMS framework provides discovery, conﬁguration, and

notiﬁcation for EMS monitors. Depending on the monitor, EMS may actively poll or it may

wait for event messages. It compares the return value with the threshold conﬁgured in

the request. If it matches, the framework sends notiﬁcation to the source speciﬁed,

through a required protocol.

• EMS Graphical User Interface (GUI) - You can invoke the EMS interface from the

Resource Management icon in System Administration Manager (SAM). From the EMS

graphical user interface (GUI), you can create, modify, and remove monitoring requests.

You can also view the list of available resources that EMS has discovered on your system,

and a list of all currently conﬁgured monitoring requests.

• EMS Command Line Interface (CLI) - You can invoke the EMS command-line

interface by typing emscli with the appropriate option at the HP-UX command-line

prompt. You can use the emscli command-line utility to create, modify, and remove

monitoring requests. You can also view the list of available resources that EMS has

discovered on your system, and a list of all currently conﬁgured monitoring requests. It is

also enabled with a help feature, emscli -h, to view the usage of various options

supported by emscli. For more information on the command line options supported by

emscli, refer to the emscli(1m) manpage.

• Management Information Base (MIB) Monitors - The following Management

Information Base (MIB) monitors are provided with the EMS framework:

— HA Cluster Monitor checks the status of clusters, nodes, packages, and services of

Serviceguard.

— HA Network Interface Monitor reports the status of LAN interfaces.
