Planning the Sun Cluster HA for SWIFTAlliance Access Installation and Configuration

This section contains the information you need to plan your Sun Cluster HA for SWIFTAlliance Access installation and configuration.

Configuration Restrictions

Your data service configuration might not be supported if you do not observe these restrictions.

Consider the restrictions in this section to plan the installation and configuration of Sun Cluster HA for SWIFTAlliance Access. This section provides a list of software and hardware configuration restrictions that apply to Sun Cluster HA for SWIFTAlliance Access only.

For restrictions that apply to all data services, see the Sun Cluster Release Notes.

• The Sun Cluster HA for SWIFTAlliance Access can only be configured as a HA agent and not as a scalable agent.

• The SWIFTAlliance Access software should be installed on a global filesystem. Best practice is to use a failover filesystem. The IBM DCE software must be installed on local storage.

Configuration Requirements

Your data service configuration might not be supported if you do not adhere to these requirements.

Use the requirements in this section to plan the installation and configuration of Sun Cluster HA for SWIFTAlliance Access. These requirements apply to Sun Cluster HA for SWIFTAlliance Access only. You must meet these requirements before you proceed with your Sun Cluster HA for SWIFTAlliance Access installation and configuration. Follow the SWIFTAlliance Access installation guide for the installation of the mandatory patch levels and the installation of the software itself.

• Sun Cluster components and their dependencies —The Sun Cluster HA for SWIFTAlliance Access data service can be configured to protect a Sun Cluster instance and its respective components. These components, and their dependencies between each other, are briefly described below.

  Table 1–3 Sun Cluster components and their dependencies (via -> symbol)

  Component	Description
  DCE daemon	-> SUNW.LogicalHost resource
  SWIFTAlliance Access	-> SUNW.LogicalHostresource -> SUNW.HAStoragePlus resource The SUNW.HAStoragePlus resource manages the SWIFTAlliance Access System Mount points and ensures that Sun Cluster is not started until these are mounted.  -> DCE daemon

  The Sun Cluster component has two configuration and registration files under /opt/SUNWscsaa/util. These files allow you to register the Sun Cluster component with Sun Cluster with default values.

  Within these files, the appropriate dependencies have already been defined. If you decide to use different names for the resources then update the saa_config file before you run the saa_register script
