to move the virtual host. The virtual host may then remain active on a server with a
failed monitored service. HP Scalable NAS will avoid this situation if there is a healthy
server configured and available, but sometimes it may not be possible in a
multiple-failure scenario.

HP Scalable NAS supports the following service monitors. When configuring a
monitor, you will need to supply the following information.

FTP service monitor
By default the FTP service monitor probes TCP port 21 of the virtual host address.
You can change this port number to the port number configured for your FTP server.
The default frequency of the probe is every 30 seconds. The default time that the
service monitor waits for a probe to complete is five seconds.
The probe function attempts to connect to port 21 and expects to read an initial
message from the FTP server. The message should begin with 220. If the probe is
successful, the monitor sends the string QUIT\n to the server. If there are no errors,
the service status remains Up. If an error occurs, the status is set to Down.
