Configure Device Monitors
HP StorageWorks Clustered File System 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 cluster.
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
HP Clustered File System 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 parameter.
