Configure Device Monitors
HP StorageWorks Clustered File System provides built-in device
monitors that can be used to watch local disks or gateway devices or to
monitor access to a SAN disk partition containing a PSFS filesystem. You
can also create custom device monitors.
Overview
HP Clustered File System 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.
Multi-Active Device Monitors
GATEWAY and DISK monitors are multi-active. This means 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 network gateway or
a SAN partition containing a PSFS filesystem. The status returned by the
monitor probe determines the placement of the associated virtual hosts.
