Chapter 17: Configure Device Monitors 210
The monitor probe queries the status of the NT service. If the status is
SERVICE_RUNNING, the service status remains Up. If the status does not
indicate that the NT service is running, the service status is set to Down.
The
NTSERVICE monitor is also available as a service monitor. When
deciding whether to create a service monitor or a device monitor,
consider the effect that you want the monitor to have on the cluster. If you
want a single virtual host to be associated with the monitor, create a
service monitor. If you want multiple virtual hosts, or no virtual hosts, to
be associated with the monitor, create a device monitor.
SHARED_FILESYSTEM Device Monitor
If you have created a virtual host for applications that obtain their data
from a
PSFS filesystem, or if you just want to monitor access to a PSFS
filesystem, you can use the
SHARED_FILESYSTEM device monitor to
ensure that the filesystem is healthy and the virtual host remains
available.
A
SHARED_FILESYSTEM device monitor is associated with a specific
PSFS filesystem. The monitor probes the filesystem at periodic intervals to
determine the filesystem health. The probe attempts to open and read a
file located on the filesystem. When you configure the monitor, you can
specify the file to be read, or you can let HP Clustered File System create a
file for this purpose.
A
SHARED_FILESYSTEM device monitor attempts to be active on each
server specified in its configuration.
The device monitor probe reports an
UP status for the filesystem only if it is mounted and file content can be
read from the filesystem.
When you create a
SHARED_FILESYSTEM device monitor, be sure to
configure the following advanced options:
• Virtual hosts. Select any virtual hosts that should fail over if the
monitor probe reports a
DOWN status for the filesystem.
• Servers. Select all servers that have mounted the filesystem and are
running the applications associated with the virtual hosts.
You might also want to create Start, Stop, or Recovery scripts to
customize the behavior of the monitor.
