PolyServe Matrix Server provides built-in device monitors that can be
used to watch disk devices or to monitor the status of PSFS filesystems.
You can also create custom device monitors.

Matrix Server provides the following types of device monitors. To
configure a device monitor, you will need to specify the probe timeout
and frequency and a monitor-specific value.

that they are active on multiple servers at the same time. This
configuration allows the device monitor to probe a shared resource such
as a PSFS filesystem. The status returned by the monitor probe
