Configuring a Data Service for Oracle VM Server for SPARC by Using a Graphical Wizard

来源:转载

In earlier releases of Oracle Solaris Cluster, you were able to configure a data service (sometimes also referred to as an agent) for Oracle VM Server for SPARC only manually using a command line interface. This was tedious, requiring the administrator to run commands on multiple nodes.

With Oracle Solaris Cluster 4.3 comes a new graphical wizard that simplifies the configuration considerably. The wizard, using a few clicks, makes a guest domain, as a black box entity, highly available.

This entry focuses on the configuration of Oracle VM Server for SPARC as a data service. The link at Oracle Solaris Cluster Manager: Getting Started provides details around installing the Oracle Solaris Cluster Manager browser interface and getting authenticated.

Launching the wizard

Once you are authenticated to the Oracle Solaris Cluster Manager browser interface, you can launch the wizard by clicking on the Oracle VM Server for SPARC button in the Tasks page.

What the wizard does in a nutshell

Preparing the domain configuration and creating the guest domain on any one of the cluster nodes is a manual step that you have to complete before the wizard can be launched.

Once the guest domain is created, you can select that guest domain using the wizard and the wizard will:

Replicate the service configuration from the target node to all other potential primary nodes in the cluster

Configure an HAStoragePlus resource to manage all the devices and file systems being used by the guest domain

Register the data service for Oracle VM Server for SPARC

Place the guest domain under the control of Oracle Solaris Cluster

All this with just a few clicks.

What the wizard does under the covers

Discovers all existing guest domains on the cluster that are not already being managed by any Oracle Solaris Cluster resource.

Replicates the service configuration from the node where the guest domain has been configured to all other potential primary nodes in the cluster.

Prompts you for all information necessary to generate a data service configuration for a SPARC guest domain in a failover setup.

Gives you the ability to co-locate the guest domain to be configured for HA with an existing guest domain already made HA.

Discovers configuration properties and validates your selections at each step.

Performs cluster-wide validation of the environment before proceeding with the configuration.

Configures resources and resource groups for the guest domain with an offline-restart dependency on the storage resources managing the devices and file systems used by the guest domain.

Brings the data service online.

Does a rollback in case the configuration of any resource or resource group fails.

Resource group topology view

The Resource Group topology view below (Topology is a tab on the Resource Groups page) displays a failover SPARC guest domain that is created by the wizard. This shows a failover configuration using a single resource group.

The arrow depicts an offline-restart dependency between the resources.
