Configure Device Monitors
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.
Overview
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.
Activity Types for Device Monitors
The activity type specifies where the device monitor can be active. The
activity type can be one of the following:
• Single-Active. The monitor is active on only one of the selected
servers. Upon server failure, the monitor will fail over to an active
server unless all associated service and device monitors are down.
