4.1.0 HP PolyServe Matrix Server administration guide (T5392-96073, October 2010)

For example, if you are creating a SHARED_FILEYSTEM monitor to check access to
a SAN partition containing a PSFS filesystem, select the virtual hosts associated with
applications that access data on that PSFS filesystem.
As another example, you might have a DISK monitor for a disk containing Web and
FTP files. If the disk fails, you want Matrix Server to fail over the virtual hosts for these
services. The server might also provide mail service; however, the virtual host for this
service is not dependent on the disk and should not fail over if the disk fails.
To specify virtual hosts from the command line, use this option:
--vhosts <vhost1>,<vhost2>,...
Servers for device monitors
The Servers tab allows you to select the servers on which the device monitor will be
configured. You can also set some options related to the monitor probe operation
and failover.

to conduct the probe only on the server where the monitor is active. Select Multi-Probe
to conduct the probe on all servers configured for the monitor.
Activity Type. Where the monitor can be active. The options are:
