The Oracle Solaris Cluster highly available environment ensures that critical applications are available to end users. The system administrator's job is to make sure that the Oracle Solaris Cluster configuration is stable and operational.
Oracle Solaris Cluster administration is organized into tasks among the following manuals.
Standard tasks, used to administer and maintain the global cluster or the zone cluster on a regular or even daily basis. These tasks are described in this guide.
Data service tasks, such as installation, configuration, and changing properties. These tasks are described in the Planning and Administering Data Services for Oracle Solaris Cluster 4.4.
Service tasks, such as adding or repairing storage or network hardware. These tasks are described in the Managing Hardware With Oracle Solaris Cluster 4.4.
In general, you can perform Oracle Solaris Cluster administration tasks while the cluster is operational. If you need take a node out of the cluster or even shut down the node, you can do so while the rest of the nodes continue cluster operations. Unless otherwise indicated, Oracle Solaris Cluster administrative tasks should be performed in the global-cluster node. For those procedures that require the entire cluster to be shut down, minimize impact on the system by scheduling downtime outside normal working hours. If you plan to shut down the cluster or a cluster node, notify users in advance.
