HP StorageWorks Clustered File System 3.2.1 Windows Storage Server Edition Administration Guide (February 2006)

Chapter 12: Configure Device Monitors 131
Virtual Hosts
The Virtual Hosts tab lets you specify the virtual hosts that will fail over if
the monitor detects a failure.
When a device monitor detects a failure, HP Clustered File System
attempts to fail over the active virtual hosts associated with that 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, if you are creating a
DISK 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 HP Clustered File System 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.
