Chapter 4. Cluster Administration
Service Status
Description
Started
The service resources are configured and available on the cluster
system that owns the service.
Pending
The service has failed on a member and is pending start on
another member.
Disabled
The service has been disabled, and does not have an assigned
owner. A disabled service is never restarted automatically by the
cluster.
Stopped
The service is not running; it is waiting for a member capable of
starting the service. A service remains in the stopped state if
autostart is disabled.
Failed
The service has failed to start on the cluster and cannot
successfully stop the service. A failed service is never restarted
automatically by the cluster.

tomatically updates the status every 10 seconds. Additionally, you can display a snapshot
of the current cluster status from a shell prompt by invoking the
clustat
utility. Example
