Sun Cluster provides both a graphical user interface and a set of commands for administering a cluster.
install a cluster
administer a cluster
create and configure resources and resource groups
configure data services with the Sun Cluster software
See the Sun Cluster 3.1 Software Installation Guide for instructions on how to install SunPlex Manager and how to use SunPlex Manager to install cluster software. SunPlex Manager provides online help for most administrative tasks.
The scrgadm command allows viewing, creating, configuring and deleting the resource type, resource group, and resource objects used by the RGM. The command is part of the administrative interface for the cluster, and is not to be used in the same programming context as the application interface described in the rest of this chapter. However, scrgadm is the tool for constructing the cluster configuration in which the API operates. Understanding the administrative interface sets the context for understanding the application interface. Refer to the scrgadm(1M) man page for details on the administrative tasks that can be performed by the command.
The scswitch command switches resource groups online and offline on specified nodes and enables or disables a resource or its monitor. See the scswitch(1M) man page for details on the administrative tasks that the command can perform.
The scstat -g command shows the current dynamic state of all resource groups and resources.
