NESiGate Modification Policy

NESiGate is an appliance that contains proprietary software and firmware. Modifications to the soft-

ware, firmware, or hardware platform that are not specifically authorized by NESi are prohibited.

Examples of prohibited activities include (but are not limited to) the following items:

•Installing other software on NESiGate

•Modifying the file system (including adding, deleting, or moving files and/or directories, or

changing permission levels, ownership, or other attributes of files and/or directories)

•Adding or deleting user accounts

•Starting or stopping system services

•Adding or removing hardware components

Any unauthorized modifications to NESiGate may affect its operation and/or obstruct NESi’s ability to

diagnose problems and provide corrections. Any work resulting from unauthorized modifications shall

be paid by the customer at NESi’s then-current support rates and may result in the immediate termina-

tion of warranty/support coverage.

MAN-REF-CASW Page 1

This manual provides an overview of the procedures used to integrate and customize the NetEx/IP com-

ponents onto a NESiGate-CA host channel platform, and to provide a description of the command and

web browser interfaces.

This manual is divided into four sections:

1) Integration: Integration of NESiGate software on the hardware platform is covered in the NESi-

Gate Software Installation Guide. Refer to that guide, then return to this manual to complete the

configuration of NESiGate as an Channel Adapter (CA) type device

2) Customization: this section is targeted to the end-user who is responsible for customizing NESi-

Gate for use as a host-based NetEx/IP channel device. It is assumed the NESiGate already has the

appropriate NESiGate-OS installed. To complete the customization, the reader must be familiar

with channel device and network addressing concepts.

3) Web Browser Interface: this section is targeted to the end-user who is responsible for customizing

the NESiGate for use as a host-based NetEx/IP channel device, and who is responsible for configur-

ing and controlling operational aspects of the device.

Introduction

MAN-REF-CASW Customization Page 3

Overview

This section provides an overview of the procedures used to complete the customization of the NESi-

Gate-CA for use with Host-Based NetEx/IP products. This section is targeted to the end-user responsi-

ble for customization. The reader must be familiar with channel device and network addressing con-

cepts.

Configure NESiGate

There are three important addressing elements involved in delivering NetEx/IP channel data that is not

IP-aware, and transferring it over an IP network to the correct destination:

• Device Number

• GNA Address

• IP Address

Device Number

The Device Number on the host and Device Index on the NESiGate channel board are numeric repre-

sentations of the same unique "device". On the Host operating system, a "Device Number" is defined as

a Unit Address on a Logical Control Unit (a physical control unit may consist of from 1-16 logical con-

trol units). The Physical Control Unit may be connected to a Port on an ESCON Director. Multiple

inbound Host channels may be connected to the ESCON Director and provide connectivity to the device

from multiple partitions (LPARs) across multiple hosts.

Similarly, on the NESiGate ESCON board, a "Device Index" is defined as a Unit Address on a Logical

Control Unit (up to 16 may exist). The Physical Control Unit may be connected to a Port on an ESCON

Director, which may provide connectivity to multiple LPARs across multiple hosts.

Since both the Device Number and Device Index represent the same unique device (from different per-

spectives), the same addressing components must be specified exactly the same in both definitions.

Failure to do so will prevent the NESiGate devices from functioning properly.

When defining devices on the ESCON channel board, the following items are specified: Device Unit

Address, Logical Control Unit, the Director port to which the host channel is connected, and Partition-id

(LPAR). The Device Index values are not specified by the user. They are automatically generated

when the channel configuration is defined.

A maximum of 64 devices are supported on each ESCON interface.

Refer to the “Channel Define Interface” button on page 66614 for a description of defining the channel de-

vices.

Page 4Customization MAN-REF-CASW

GNA Address

The GNA address represents a NetEx/IP network address that is associated with a given device. It is

specified in the NetEx/IP Network Configuration Table (NCT). It is also specified during the customi-

zation of the NESiGate Channel Driver. At that time, an association is established between a particular

GNA address and a Device Index.

IP Address

The IP address represents a NetEx/IP network node address. There is no channel device awareness in-

herent in an IP address. However, during the NESiGate customization task, IP host names are defined,

each having a format based on its GNA address. This enables NESiGate to perform a direct mapping

between GNA and IP addresses. This mapping is transparent to the NetEx/IP running on the host, as

well as to all NetEx/IP applications.

Using a Web Browser to Configure NESiGate

The NESiGate Web Browser Interface may be used to configure NESiGate. Before configuring the

NG-CA specific items, the common System and Network configuration should be completed. See the

“Installation Guide” (NG-SW) manual for details.

Refer to the "Web Browser Interface" section on page 7 for a complete description of the commands

used in this section.

Define the Channel Boards(s)

The channel board(s) are automatically configured by the NESiGate initialization software. Normally,

no re-configuration of the board config is required.

Define the Devices

This step is required. If this step is not performed, the ESCON devices will respond as the correct de-

vice without regard to LPAR or ESCON director port affinity. If this does not match the real configura-

tion, incorrect results will occur.

Select the Board/Channel link in the navigation menu. This will open the page that is titled: NESiGate

CA Board/Channel.

Using the device configuration data from a completed worksheet provided in “Appendix A: Configura-

tion Worksheet” on page 25, use the "Channel Define Interface" button to define the devices. Refer to

page 14 for a description of this command.

Repeat this step as many times as necessary until all required channel interfaces are defined.
