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

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.
