Prepare DNS for the System

Before You Begin

You must finish the following tasks before the system arrives. Installation and the initial configuration cannot proceed until these tasks are finished.

1. Provide the necessary information in the following documents:

   • SPARC SuperCluster T4-4 Site Checklists

   • The configuration worksheet document for your type of system

2. Use the host names and IP addresses specified in the completed configuration worksheets document to create and register Domain Name System (DNS) addresses for the system.

   All public addresses, single client access name (SCAN) addresses, and VIP addresses must also be registered in DNS prior to installation.

   ---

   Note -  The configuration worksheets document defines the SCAN as a single name with three IP addresses on the client access network.

   ---

3. Configure all addresses registered in DNS for both forward resolution and reverse resolution.

   Reverse resolution must be forward confirmed (forward-confirmed reverse DNS) such that both the forward and reverse DNS entries match each other.

   The SCAN name to the three SCAN addresses must be configured in DNS for round robin resolution.
