Resource Group Manager Administrative Interface

Sun Cluster provides both a graphical user interface (GUI) and a set of commands for administering a cluster.

Sun Cluster Manager

Sun Cluster Manager, formerly SunPlex^TM Manager, is a web-based tool that enables you to perform the following tasks:

• 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 Software Installation Guide for Solaris OS for instructions on how to install Sun Cluster Manager and how to use Sun Cluster Manager to install cluster software. Sun Cluster Manager provides online help for most unique administrative tasks.

clsetup Utility

You can perform most Sun Cluster administration tasks interactively with the clsetup(1CL) utility.

You can administer the following Sun Cluster elements with the clsetup utility:

• Quorum

• Resource groups

• Data services

• Cluster interconnect

• Device groups and volumes

• Private host names

• New nodes

• Other cluster tasks

You can also perform the following operations with the clsetup utility:

• Create a resource group

• Add a network resource to a resource group

• Add a data service resource to a resource group

• Register a resource type

• Bring a resource group online or offline

• Switchover a resource group

• Suspend or resume the automatic recovery actions of a resource group

• Enable or disable a resource

• Change resource group properties

• Change resource properties

• Remove a resource from a resource group

• Remove a resource group

• Clear the Stop_failed error flag from a resource

Administrative Commands

The Sun Cluster commands for administering RGM objects are clresourcetype, clresourcegroup, clresource, clnode, and cluster.

The clresourcetype, clresourcegroup, and clresource commands enable you to view, create, configure, and delete a resource type, a resource group, and the resource objects that are used by the RGM. These commands are part of the administrative interface for the cluster, but are not to be used in the same programming context as the application interface that is described in the rest of this chapter. However, the clresourcetype, clresourcegroup, and clresource commands are the tools for constructing the cluster configuration in which the API operates. Understanding the administrative interface sets the context for understanding the application interface. See the clresourcetype(1CL), clresourcegroup(1CL), and clresource(1CL) man pages for details about the administrative tasks that you can perform with these commands.
