Announcements

Versios A.03.00.01 of High Availability Monitors (B5736BA), include

media, license and manual. Version A.03.00.01 runs on HP-UX 10.20 and

HP-UX 11.0. The following high availability monitors are included in

this bundle:

• HA Cluster Monitor checks the status of MC/ServiceGuard and

MC/LockManager clusters and detects failed clusters, nodes, or

packages.

• HA Disk Monitor checks the status of LVM managed disks and

detects disconnected busses, power-failed or missing disks, and stale

or missing mirrors. It provides summary status for both physical and

logical volumes in a volume group as well as individual status for

each disk, link and logical volume.

• HA Network Monitor reports the status of LAN interfaces.

• HA System Resource Monitor checks the status of users, system load,

and ﬁle system space.

The HA Monitors bundle depends on, and includes, the Event Monitoring

Services (EMS) (B7609BA). When you install HA Monitors, the install

process automatically picks up and installs EMS.

The Event Monitoring Service has two main parts:

• The EMS framework registers monitors. It can query monitors,

accept status messages, interpret them according to your conﬁgured

monitoring requests, and send notiﬁcation when and where you

requested.

• The EMS graphical interface runs under SAM and allows you to

create, modify, and remove monitoring requests. It also displays a list

of all current monitors and requests.

To conﬁgure a monitoring request, open EMS. First, logon as root and

type SAM to open the HP-UX System Administration Manager. In SAM,

double-click to open Resource Management, then open EMS. EMS shows

you a list of all the conﬁgured monitoring requests. If you want to add a

monitoring request, you can navigate through the list of discovered and

available resources.

You can conﬁgure more than one request for each HA monitor. For
