Installing and Removing EMS HA Monitors

To make best use of EMS HA Monitors, install and conﬁgure them on all systems in your environment. Because EMS monitors resources for the local system only, you need to install EMS on every system to monitor all systems.

EMS HA Monitors run on HP 9000 Series 800 systems running HP-UX version 10.20 or later.

Hardware, such as disks and LAN cards, should be conﬁgured and tested before installing EMS HA Monitors.

Installing EMS HA Monitors

The EMS HA Monitor bundle (P/N B5735AA-APZ) and license (P/NB5736AA-APZ) version A.01.00 contains these products:

EMS-Core	the EMS framework
EMS-Conﬁg	the SAM interface to EMS
EMS-Disk Monitor	the disk monitor, associated dictionary and ﬁles
EMS-MIB Monitor	the cluster, network, and system resource monitors,
	associated dictionary and ﬁles

To install EMS product, use swinstall, or the Software Management area in SAM.

If you have many systems, it may be easier to install over the network from a central location. Create a network depot according to the instructions in Managing HP-UX Software with SD-UX, rlogin or telnet to the remote host, and install over the network from the depot.

When monitors are updated, or you install a monitor on top of an existing monitor, your requests are retained. This is part of the functionality provided by the persistence client; see “Making Sure Monitors are Running” in Chapter 6.

Note that updated monitors may have new status values that change the meaning of your monitoring requests.
