Introduction

Cisco Network Boot is a product that allows you to boot a computer without an attached disk drive. Cisco Network Boot supports a boot of the following operating systems:

Microsoft Windows 2000

Microsoft Windows XP

Microsoft Windows Server 2003

Various Linux operating systems, via the Replication Utility for Linux and the iSCSI driver for Linux, available as Open Source from SourceForge. See the readme files that accompany the software downloads for detailed configuration and usage information.

With Cisco Network Boot, a computer without a directly attached disk drive uses iSCSI protocol via an iSCSI driver to boot from an iSCSI disk through an IP network and a Cisco SN 5400 or MDS 9000 Series system (see Figure 1). As with any iSCSI disk, even though it is not directly attached to the computer accessing it, the disk appears to the computer as if it were directly attached.


Note The iSCSI protocol is an IETF-defined protocol for IP storage (ips). For more information about the iSCSI protocol, refer to the IETF standards for IP storage at http://www.ietf.org.

System Requirements

Table 1 describes the system requirements for hosts, the DHCP and TFTP servers, and the iSCSI targets that utilize Cisco Network Boot.

Table 1 Cisco Network Boot System Requirements 

Item
Requirements

Master boot host

IBM PC-compatible computer with an Intel Pentium III or higher processor, with BIOS support for PXE 2.1 or later.

A network interface and NIC supported by PXE.

A directly attached disk drive configured with a supported operating system and the appropriate iSCSI driver.

Cisco Network Boot supports the following Microsoft Windows operating systems, with the Cisco iSCSI driver version 3.1.2 (or later) for Microsoft Windows:

Microsoft Windows 2000 (Professional, Advanced or Datacenter Server) with Service Pack 3 (or higher)

Microsoft Windows XP (Professional Edition) with Service Pack 2 (or higher)

Microsoft Windows Server 2003 (Enterprise, Standard or Web Edition) with Service Pack 1 (or higher)

Note If you are using the dynamic IP address boot feature of Cisco Network Boot, you must use the Cisco iSCSI driver version 4.2.1 (or later) for Microsoft Windows.

Note Cisco Network Boot also supports a boot of various Linux operating systems, with the Linux iSCSI driver version 3.4.1 (or later) and the Replication Utility for Linux. The iSCSI driver and the Replication Utility are both Open Source, and are available from SourceForge. See the readme files that accompany the software downloads for detailed requirements, configuration and usage information.

Other hosts

IBM PC-compatible computer with an Intel Pentium III or higher processor, with BIOS support for PXE 2.1 or later.

A network interface supported by PXE.

Note The hardware must be identical to the master boot host hardware, including identical network hardware and connections.

DHCP and TFTP servers

A DHCP server configured with reserved IP addresses for each host.

A TFTP server to transfer the iNBP.com file to the host.

Note One server may provide both functions.

iSCSI targets

iSCSI targets configured on one or more of the following systems:

SN 5428 Storage Router, running software release 3.2 or later

SN 5428-2 Storage Router

MDS 9000 Series system, running SAN-OS Release 1.1(1) or later

A suitable storage device (JBOD or storage array) with sufficient space to hold the boot image. The iSCSI target block size must be 512 bytes.

Note Storage arrays are recommended because they provide redundancy and are more flexible than JBODs.

Network equipment

Cisco SN 5400 or MDS 9000 Series system.

Ethernet switch or hub (optional).

Fibre Channel switch or hub (optional).



Note Refer to the Cisco.com website for interoperability information.


New and Changed Information

Support for static or dynamic IP addresses—Allows any NIC that is PXE enabled to be configured with either a static or dynamic IP address.

CDP support—Cisco Discovery Protocol (CDP) is automatically supported by Cisco Network Boot.

Open Source Linux Replication Utility—The Linux Replication Utility has been enhanced and is now available as Open Source from SourceForge.

Enhanced iSCSI target support—Cisco Network Boot now supports shortened iSCSI target names.

Boot from non-0 LUN—Allows a Microsoft Windows system to boot from a LUN that is not LUN 0.

Command Line Utility—A CLI is now available that can be used manually or in command scripts to automate the replication process.

See the readme file for additional information about all new features.

CSCed13016

When running Microsoft Windows 2000 with Service Pack 4, Cisco Network Boot may fail to produce an image that boots successfully.

Workaround: None. This problem is resolved in release 3.3.1

CSCin76983

If "Enable SCSI failure on Boot Target" is disabled for a Windows 2000 Advanced Server booted from an iSCSI disk, a relogin attempt from the MMC application may cause the system to freeze and the MMC console to become non-responsive.

http://tools.cisco.com/RPF/register/register.do


Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.


Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
