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.)
