Purpose

The purpose of this document is to provide the description of the design verification procedure necessary to verify Lustre operation with IPv6 feature. The procedure is not isolated to testing specific Lustre modules but rather Lustre as a complete system. 

Scope

This document covers design verification procedures for an IPv6-only system and a mixed IPv6-IPv4 system with the focus on IPv6 functionality. Testing of IPv4-only system is considered to be regression testing with regard to the IPv6 feature and is not covered by this document. 

Requirements

The requirements for executing this test plan are same as for a regular Lustre system testing with the exception that every node involved in this testing is expected to be able to work with IPv6.

HW Requirements

A pool of server nodes and a pool of client nodes is expected to be available. Exact numbers are TBD

Network Requirements

Each node is expected to have at least two interfaces available for the purpose of LNet configuration. The connection between the nodes should be such that both IPv4 and IPv6 can be supported on every link.

While majority of the testing is projected to use TCP/Ethernet networking, IPv6 with o2ib shall also be tested.

SW Requirements

Exact Lustre SW version to be used is TBD. Linux kernel versions to be used are TBD.

Testing Procedure

Test Case Structure

The test is defined as the combination of the following:

Identifier

Label which uniquely identifies the testcase.

Objective

Description of what the test case is verifying. Ideally refers to a specific requirement from a system design document which is being verified.

Procedure

Describes the test setup and procedure. Level of detail should be sufficient for a test engineer to follow (should not rely on information available to developers only).

Expected Behaviour

Describes how the system is expected to behave when test procedure is executed.

Actual Results

Describes actual results observed when the test case is executed.
