3.5.1 Matrix Server Administration Guide

Chapter 14: Configure Device Monitors 249

When a device monitor detects a failure, Matrix Server attempts to fail

over the active virtual hosts associated with that device monitor. By

default, all virtual hosts on the servers used with the device monitor are

dependent on the device monitor. However, you can specify that only

certain virtual hosts be dependent on the device monitor.

For 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.

If you are creating a

SHARED_FILESYSTEM monitor, select the virtual

hosts associated with applications that access data on the PSFS filesystem

being monitored.

To specify virtual hosts from the command line, use this option:

--vhosts <vhost1>,<vhost2>,...
