Preface

This manual briefly explains the operations that need to be performed by the user in order to connect an

ETERNUS DX to a server running Linux and using Converged Network Adapter cards via an FCoE interface.

This manual is used when performing the setup procedure described in "Installing Drivers and Setting Up the

Server" of the "Configuration Guide -Server Connection- (FCoE) for Linux".

This manual should be used in conjunction with any other applicable user manuals, such as those for the

ETERNUS DX, server, OS, Converged Network Adapter cards, and drivers.

Refer to "Configuration Guide -Server Connection- Notations" for the notations used in this manual such as

product trademarks and product names. For storage systems that are supported by the OS, refer to the Server

Support Matrix of the ETERNUS DX.

Chapter 1

Setup Procedure for Emulex Converged Network

Adapter Cards

This chapter describes the workflow required to establish a connection between a server with Emulex Con-

verged Network Adapter cards and an ETERNUS DX.

1.1 Workflow

All work after this point requires "root" privileges.

When using Linux supported Converged Network Adapter cards, this procedure is used for all OS architectures

(e.g. x86, Intel64), Converged Network Adapter cards, and driver versions.

Workflow

Setting Up the Converged Network Adapter Cards

Install the Converged Network Adapter cards, acquire their physical addresses and WWN information.

•"1.2 Setting Up the Converged Network Adapter Cards" (page 6)

Setting Up the Driver Parameters

Set the driver parameters by editing the configuration file.

•"1.4 Setting Up the Driver Parameters" (page 8)

FUJITSU Storage ETERNUS DX Configuration Guide -Server Connection- (FCoE) for Linux

P3AM-6402-11ENZ0

Creating an Initial RAM Disk

Create an initial RAM disk to match the kernel being used.

•"1.5 Creating an Initial RAM Disk" (page 10)

Now proceed to the next workflow described in "Connecting the Server to the ETERNUS DX storage sys-

tems" of the "Configuration Guide -Server Connection- (FCoE) for Linux".

1.2 Setting Up the Converged Network Adapter Cards

Install the Converged Network Adapter card to the server, and acquire the physical address and World Wide

Name (WWN) for the Converged Network Adapter card.

•The physical address and WWN of a Converged Network Adapter card are required information in the fol-

lowing cases: when an error has occurred in the system, when using the ETERNUS DX storage systems (se-

curity function, host affinity function, etc.) to restrict server access, or when connecting the ETERNUS DX

storage systems and the server using a Fibre Channel switch and a CEE/FCoE switch.

•Acquire the physical address and WWN when installing the Converged Network Adapter card, because the

relationship between a physical address and WWN cannot be determined from BIOS and OS. Physical ad-

dress and WWN must be assigned to "WWN instance management table for the server".

The workflow is shown below.

(1) Install the Converged Network Adapter card

(2) Turn on the server

(3) Acquire the physical address and WWN for the Converged Network Adapter card

(4) Add a record for the server in the WWN instance management table for the server

When installing two or more Converged Network Adapter cards in the server, first turn off the server, then

repeat Steps (1) through (4) above for each Converged Network Adapter card to be installed.

The procedure is as follows:

1Install the Converged Network Adapter card in the server.

For the installation method, slot positions, activation of the installed slot, and notes regarding the Con-

verged Network Adapter card, refer to the Converged Network Adapter card documentation or the User's

Guide of the server.

2Turn on the server, and press the [Alt] + [E] keys or [Ctrl] + [E] keys while the following message is

displayed.

!!! Emulex OneConnect FCoE BIOS !!!, Version 4.01a0

Press <Alt E> or <Ctrl E> to enter Emulex BIOS configuration

utility. Press <s> to skip Emulex BIOS

Emulex OneConnect FCoE BIOS Utility starts.

3Select the Converged Network Adapter card from which information is to be obtained with the [h] and

[i] keys. Press the [Enter] key.

4Check the [Mem Base] and [Port Name] values.

The value of [Mem Base] is the physical address and the value of [Port Name] is the Converged Net-

work Adapter card WWN.

5Record the physical address and WWN in the "WWN instance management table for the server".

Refer to "Appendix A WWN Instance Management Table for the Server (Blank)" (page 19).

The following shows an example of this.

Details of contents

The details of contents for the WWN instance management table for the server are as follows:

Host name:

Record the host name.

IP Address:

Record the IP address of the server.

Physical slot name:

Record the slot position of installed Converged Network Adapter card.

For the installation location, refer to the User's Guide for each server.

Converged Network Adapter card WWN:

Record the [Port Name] value. This value can be confirmed in Step 4.

Instance name:

Not necessary to record.

Physical address:

Record the [Mem Base] value. This value can be confirmed in Step 4.

Cable tag:

Record a tag name which indicates the connection path (relationship between the connected device

and the port).

6Press the [Esc] key to quit the Emulex OneConnect FCoE BIOS Utility.

When installing two or more Converged Network Adapter cards to the server, first turn off the server,

then repeat Step 1 through Step 6 shown here for each Converged Network Adapter card to be installed.

If multiple Converged Network Adapter cards are already installed in the server at the time of pur-

chase, the one-to-one relationship between the WWNs and the Converged Network Adapter cards

cannot be recognized. The WWNs that are obtained in this section may need to be repeatedly regis-

tered and set up on the ETERNUS DX until a server recognizes the ETERNUS DX logical disks.

For details about ETERNUS DX settings, refer to "Configuration Guide -Server Connection- Storage Sys-

tem Settings" that corresponds to the ETERNUS DX to be connected.

1.3 Installing the Converged Network Adapter Card Driver

Check whether the Converged Network Adapter card driver is the OS standard driver or not. If the Converged

Network Adapter card requires a non-standard driver, check the driver versions using the "Server Support Ma-

trix".

•When the Converged Network Adapter card requires a standard kernel package driver

The standard add-on driver for the OS should be used.

•When the Converged Network Adapter card requires a non-standard driver

Download and install the driver specified in the "Server Support Matrix" from the Emulex Corp. web-site.

Installation of applications, such as OneCommand Manager, is also required. Refer to the Emulex Con-

verged Network Adapter card manual for details on the installation method.

1.4 Setting Up the Driver Parameters

Use an editor such as "vi" to add the setting values to the configuration file.

Note that the setting values and details vary depending on the OS vender, version, whether the ETERNUS

Multipath Driver is used, and the storage system that is used.

-Use the value of "8" if the actual result is lower. Use the maximum value if the actual result exceeds

the maximum value for the driver.

-To achieve maximum system performance, this value can be changed according to the server load

and the peak operating times.

-The number of simultaneous command executions per CA port for the ETERNUS DX is limited to

1024. This value is used by multiple servers that share the CA port. A maximum of 1024 commands

can be executed per CA port.

1.5 Creating an Initial RAM Disk

Create an initial RAM disk image file to match the kernel being used. Refer to the Emulex Converged Network

Adapter card manual for details on the creation method.

1.6 Rebooting the OS

Reboot the OS. When the Converged Network Adapter card requires a non-standard driver, check the files in

"/var/log/messages" and confirm that the correct version of the Converged Network Adapter card driver has

been installed after rebooting the OS.
