About This Guide


This preface describes the objectives, audience, organization and command syntax conventions of the Cisco SN 5420 Storage Router Software Configuration Guide. It also provides information on how to obtain related documentation and technical assistance.

Objectives

This software configuration guide describes how to configure software in a Cisco SN 5420 Storage Router. It does not describe every possible configuration but does describe those tasks commonly required to configure the software.


Note This guide does not describe how to configure the iSCSI driver to be installed in each server requiring IP access to storage. Install and configure the Cisco Storage Networking iSCSI drivers according to the readme and example configuration files on the Cisco Storage Networking iSCSI Drivers CD shipped with your SN 5420 Storage Router. (In addition, you can access readme and example configuration files from Cisco.com.)


Audience

This guide is intended primarily for the following audiences:

System administrators who are familiar with the fundamentals of router-based internetworking and network storage devices, but who might not be familiar with the specifics of Cisco products or the routing protocols supported by Cisco products.

System administrators who are responsible for configuring network storage equipment.

Command Syntax Conventions

Table 2 describes the syntax used with the commands in this document.

Table 2 Syntax Conventions 

Convention
Description

boldface font

Indicates commands and keywords that you enter literally as shown.

italic font

Indicates arguments for which you supply values.

[ x ]

Square brackets indicate an optional element (keyword or argument).

{ x }

Braces indicate a required element (keyword or argument).

{s | y | z}

Braces and vertical bars indicate a required choice of keywords or arguments, separated by the vertical bars within the braces.

[ x {y | z}]

Braces and vertical bars within square brackets indicate a required choice within an optional element.

/bits

The value entered for /bits specifies a network mask in classless interdomain routing (CIDR) style. That is, the value equals the number of bits in a network mask counting from the most significant side (left) of an IP address. For example, a /bits value of 24 is the equivalent of a network mask of 255.255.255.0. Similarly, a /bits value of 32 specifies using the entire IP address.

"user text"

Indicates that user text (a user-defined text string) that contains a space or spaces must be enclosed using double or single quotes. If single quotes or an apostrophe is used as part of the text string, enclose the string using double quotes. If double quotes are used as part of the text string, enclose the string using single quotes.

For example, both "Pat's storage router" and `number "2"' are valid text string entries.

Note The question mark (?) character cannot be used as part of a text string.

screen font

Examples of information displayed on the screen.

boldface screen font

Examples of information you must enter.

< >

Nonprinting characters, for example, passwords appear in angle brackets.

[  ]

Default responses to system prompts appear in square brackets.



Note Means reader take note. Notes contain helpful suggestions or references to additional information and material.



Caution Means reader be careful. In this situation, you might do something that could result in equipment damage or loss of data.


Timesaver Means the described action saves time. You can save time by performing the action described in the paragraph.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

http://www.cisco.com/register/

If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In addition, please have available your service agreement number and your product serial number.
