What’s in This Version

The A.04.20 version of High Availability Monitors (HA Monitors) for HP-UX 11i v2 operating

system runs on PA-RISC and Itanium 2-based platforms.

In this release, HA Monitors supports the Node and Host Name Expansion feature, which is

available on the software pack. This feature provides you with the ability to set nodes and

host names upto 255 characters.

HA Monitors contains a suite of monitors. Among them, MIB Monitor is used for monitoring

the availability of LAN interface. In HP-UX 11i v2, with introduction of IPv6, there are new

interface monitoring MIBs. The MIB Monitor has been enabled to use the newer MIBs on

IPv6-enabled systems.

All the HA Monitors libraries are available as PA libraries.

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

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.

• The resls and resdata EMS utilities.

Deﬁne monitoring requests through EMS GUI, EMS CLI or with high availability software,

such as Serviceguard and Serviceguard Extension for RAC (formerly known as Serviceguard

OPS Edition). The EMS framework (either through the EMS GUI, EMS CLI or through

Serviceguard) displays a list of conﬁgured monitoring requests.
