Red Hat CLUSTER FOR ENTERPRISE LINUX 5.0, Configuration Manual

Page: 91 / 114

You can use the Cluster Status Tool to enable, disable, restart, or relocate a high-availability
service. The Cluster Status Tool displays the current cluster status in the Services area and
automatically updates the status every 10 seconds.
To enable a service, you can select the service in the Services area and click Enable. To
disable a service, you can select the service in the Services area and click Disable. To restart
a service, you can select the service in the Services area and click Restart. To relocate a
service from one node to another, you can drag the service to another node and drop the
service onto that node. Relocating a service restarts the service on that node. (Relocating a
service to its current node — that is, dragging a service to its current node and dropping the
service onto that node — restarts the service.)
The following tables describe the members and services status information displayed by the
Cluster Status Tool.
Members Status Description
Member
The node is part of the cluster.
Note: A node can be a member of a cluster; however, the node may
be inactive and incapable of running services. For example, if
rgmanager
is not running on the node, but all other cluster software
components are running in the node, the node appears as a Member
in the Cluster Status Tool.
Dead The node is unable to participate as a cluster member. The most
basic cluster software is not running on the node.
Table 6.1. Members Status
Services 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.
