The Probe Severity setting works with the Virtual NFS Service policy (either
AUTOFAILBACK or NOFAILBACK) to determine what happens when a monitor probe
fails.
The default policies (AUTOFAILBACK for the Virtual NFS Service and AUTORECOVER
for the Export Group monitor) cause HP Scalable NAS to fail over the associated
Virtual NFS Services to a backup network interface on another node when the monitor
probe fails. When the original node is again available, HP Scalable NAS fails back
the Virtual NFS Services to the network interfaces on the original node.
You can use the Probe Severity attribute to change this behavior. There are three
settings for Probe Severity: NOFAILOVER, AUTORECOVER, and NOAUTORECOVER.
NOFAILOVER. The Virtual NFS Services do not fail over when the monitor probe is
DOWN. Administrative intervention is required to fail over the Virtual NFS Services.
AUTORECOVER. This is the default. The Virtual NFS Services fail over when a monitor
probe fails. When the original node is again available, failback occurs according
to the failback policy for the Virtual NFS Services.
NOAUTORECOVER. The Virtual NFS Services fail over when a monitor probe fails
and the monitor is disabled on the original node, preventing automatic failback.
When the monitor is reenabled, failback occurs according to the failback policy for
the Virtual NFS Services. The NOAUTORECOVER option is useful when integrating
