This chapter describes the various administrative tasks
for maintaining a cluster after it has been installed and
configured.
The Cluster Status Tool is part of the Red Hat Cluster Suite
management GUI, (the system-config-cluster package)
and is accessed by a tab in the Red Hat Cluster Suite management GUI. The
Cluster Status Tool displays the status of
cluster members and services and provides control of cluster services.
The members and services displayed in the
Cluster Status Tool are determined by the
cluster configuration file
(/etc/cluster/cluster.conf). The cluster
configuration file is maintained via the
Cluster Configuration Tool in the cluster management GUI.

| | Do not manually edit the cluster configuration file.

You can access the Cluster Status Tool by
clicking the tab at the cluster
management GUI to Figure 4-1).
Use the Cluster Status Tool to enable,
disable, restart, or relocate a service. To enable a service, select the
service in the Services area and click
Enable. To disable a service, select the
service in the Services area and click
Disable. To restart a service, select the
service in the Services area and click
Restart. To relocate service from one member to
another, drag the service to another member and drop the service onto
that member. Relocating a member restarts the service on that
member. (Relocating a service to its current member — that is,
dragging a service to its current member and dropping the
service onto that member — restarts the service.)
