Supported hardware and software

In those instances in which procedures or parts of procedures documented here apply to some

switches but not to others, this guide identifies exactly which switches are supported and which are

not.

Although many different software and hardware configurations are tested and supported by

Brocade Communications Systems, Inc. for 6.0.0, documenting all possible configurations and

scenarios is beyond the scope of this document.

The following hardware platforms are supported by this release of Fabric OS v6.0.0 Access

Gateway Administrator’s Guide:

•Brocade 200E switch

•Brocade 4012 switch

•Brocade 4016 switch

•Brocade 4018 switch

•Brocade 4020 switch

•Brocade 4024 switch

What’s new in this document

The following changes have been made since this document was last released:

•Information that was added:

•Support for the 4018 embedded switch

•N_Port grouping policy

•Automatic Port Configuration (APC)

•Preferred Secondary N_Port mapping is an optional secondary failover path for an N_Port

•Information that was changed:

•Path Failback and Failover policies have been enabled to incorporate:

Preferred Secondary N_Port

N_Port grouping

Automatic Port Configuration (APC)

•Enhancements to the Command Line Interface (CLI)

•Information that was deleted:

•none

For further information, refer to the release notes.

Document conventions

This section describes text formatting conventions and important notices formats.

Access Gateway Administrator’s Guide vii

53-1000605-01

Text formatting

The narrative-text formatting conventions that are used in this document are as follows:

bold text Identifies command names

Identifies the names of user-manipulated GUI elements

Identifies keywords and operands

Identifies text to enter at the GUI or CLI

italic text Provides emphasis

Identifies variables

Identifies paths and Internet addresses

Identifies document titles

code text Identifies CLI output

Identifies syntax examples

For readability, command names in the narrative portions of this guide are presented in mixed

lettercase: for example, switchShow. In actual examples, command lettercase is often all

lowercase. Otherwise, this manual specifically notes those cases in which a command is case

sensitive. The ficonCupSet and ficonCupShow commands are an exception to this convention.

Notes, cautions, and warnings

The following notices appear in this document.

NOTE

A note provides a tip, emphasizes important information, or provides a reference to related

information.

ATTENTION

An Attention statement indicates potential damage to hardware or data.

CAUTION

A Caution statement alerts you to situations that can be potentially hazardous to you.

DANGER

A Danger statement indicates conditions or situations that can be potentially lethal or extremely

hazardous to you. Safety labels are also attached directly to products to warn of these conditions

or situations.

Key terms

For definitions of SAN-specific terms, visit the Storage Networking Industry Association online

dictionary at: http://www.snia.org/education/dictionary.

viii Access Gateway Administrator’s Guide

53-1000605-01

For definitions specific to Brocade and Fibre Channel, see the Brocade Glossary.

The following terms are used in this manual to describe Access Gateway mode and its

components.

Access Gateway (AG) Fabric OS mode for embedded switches that reduces SAN (storage area

network) deployment complexity by leveraging NPIV (N_Port ID virtualization).

E_Port An ISL (Interswitch link) port. A switch port that connects switches together to

form a fabric.

Edge switch A fabric switch that connects host, storage, or other devices, such as Brocade

Access Gateway, to the fabric.

F_Port A fabric port. A switch port that connects a host, HBA (host bus adaptor), or

storage device to the SAN. On Brocade Access Gateway, the F_Port connects

to a host only.

Mapping On the Brocade Access Gateway, the configuration of F_Port to N_Port routes.

N_Port A node port. A Fibre Channel host or storage port in a fabric or point-to-point

connection. On Brocade Access Gateway, the N_Port connects to the edge

switch.

NPIV N_Port ID virtualization. Allows a single Fibre Channel port to appear as

multiple, distinct ports providing separate port identification and security

zoning within the fabric for each operating system image as if each operating

system image had its own unique physical port.

Preferred Secondary N_Port

On the Brocade Access Gateway, the preferred secondary N_Port refers to

the secondary path that and F_Port failovers to if the primary N_Port goes

offline.

Getting technical help

Contact your switch support supplier for hardware, firmware, and software support, including

product repairs and part ordering. To expedite your call, have the following information available:

1. General Information

•Technical Support contract number, if applicable

•Switch model

•Switch operating system version

•Error numbers and messages received

•supportSave command output

•Detailed description of the problem, including the switch or fabric behavior immediately

following the problem, and specific questions

•Description of any troubleshooting steps already performed and the results

•Serial console and Telnet session logs

•Syslog message logs

2. Switch Serial Number

The switch serial number and corresponding bar code are provided on the serial number label,

as shown here.

xAccess Gateway Administrator’s Guide

53-1000605-01

The serial number label is located as follows:

•Brocade 200E—On the nonport side of the chassis

•Brocade 4100, 4900, and 7500—On the switch ID pull-out tab located inside the chassis

on the port side on the left

•Brocade 5000—On the switch ID pull-out tab located on the bottom of the port side of the

switch

•Brocade 7600—On the bottom of the chassis

•Brocade 48000—Inside the chassis next to the power supply bays

•Brocade DCX—On the bottom right on the port side of the chassis

3. World Wide Name (WWN)

•Use the wwn command to display the switch WWN.

•If you cannot use the wwn command because the switch is inoperable, you can get the

WWN from the same place as the serial number.
