4.0.0 HP Polyserve Matrix Server Administration Guide (T5392-96052, March 2010)

16 Configure device monitors
Matrix Server provides built-in device monitors that can be used to watch local disks,
gateway devices, or an NT service, or to monitor access to a SAN disk partition
containing a PSFS filesystem. You can also create custom device monitors.
Overview
A device monitor is configured on one or more servers in the matrix. Depending on
the type of monitor, it can be active on all servers on which it is configured, or on
only one server. By default, all virtual hosts on the servers are dependent on the
device monitor and may be failed over if the monitor probe fails. However, you can
change the configuration so that only certain virtual hosts, or no virtual hosts, are
dependent on the device monitor.
Types of device monitors
Matrix Server provides the following types of device monitors. To configure a device
monitor, you will need to specify the probe timeout the probe frequency, and a
monitor-specific value.
