Release Notes for Cisco Network Boot Release 2.1.1
October 29, 2002
Note You can find the most current documentation on Cisco.com.
These release notes support Cisco Network Boot software release 2.1.1.
For a list of software caveats that apply to Release 2.1.1, see the "Open Caveats" section. The caveats are updated for every maintenance release and are located on Cisco.com and the Documentation CD-ROM.
These release notes describe the following topics:
Cisco Network Boot is a product that allows you to initiate a boot of Microsoft Windows 2000 Server or Advanced Server on a computer without an attached disk drive.
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 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.
Figure 1 Cisco Network Boot Overview
Table 1 describes the system requirements for hosts, the DHCP/TFTP server, and the iSCSI targets that utilize Cisco Network Boot:
This section describes how to obtain updated Network Boot software, and includes the following information:
iSCSI Driver Version Support
Cisco Network Boot requires the Cisco iSCSI Driver version 2.2.1 (or later) for Microsoft Windows 2000.

Uninstalling Cisco Network Boot
To uninstall the Cisco Network Boot Administration utility, follow these instructions:
Step 1 Choose Start > Settings > Control Panel.
Step 2 Click Add/Remove Programs.
Step 3 Choose Network Boot Administration, and click Change/Remove.
Step 4 Select Remove.
Limitations and Restrictions
•The boot image must always be LUN 0.
•The storage device block size must be 512 bytes.
•All required host hardware should be identical; network interface and connections must be identical.
Caveats describe unexpected behavior or defects in Cisco Network Boot software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.
This document describes open severity 1 and 2 caveats, and selected caveats of other severities. For a more complete list of caveats against this release, access Cisco.com as described in the section "Cisco.com" at the end of this document.
Note If you have an account with Cisco.com, you can use Bug Navigator II to find caveats of any severity for any release. You can reach Bug Navigator II on Cisco.com at Service & Support:
The Cisco Network Boot replication process does not create a unique SID for the computer; replicating and booting multiple computers will result in each system having the same SID. Some applications use the computer SID for security (workgroups), and if the SID is not unique, the application will not be able to tell the computers apart.
Workaround: A utility named "newsid" is available from http://www.sysinternals.com. You can use this utility to assign a new SID.
Booting a Compaq DL380 with an Insight card using the CpqRib.sys driver version 126.96.36.199 may result in a Microsoft Windows "blue screen" and error code 0x00000050.
Workaround: Remove the Insight card from the computer.
If a user creates a directory on a server to be replicated, the replication utility will fail attempting to copy data from that directory. The log file shows data being copied from a user directory.
Workaround: Do not allow user directories on the master replication copy. If user directories are present, change the owner to Administrator prior to the replication process. After replication, change the owner back to the user.
Cisco Network Boot does not officially support configuring DHCP and TFTP servers at separate IP addresses.
Workaround: In the following example procedure, the DHCP server IP address will be 10.1.1.1 and the TFTP server IP address will be 10.1.1.2. It should not matter whether the TFTP and DHCP servers run the same operating system.
–Configure the DHCP server at 10.1.1.1.
–Configure the TFTP server at 10.1.1.2, and install inbp.com.
–If the DHCP server is running on a Microsoft Windows platform, add Option 66 "Boot Server Host Name" to the reservation(s) requiring it, or as a scope-wide option. Set the option value to the IP address of the TFTP server (in this example, 10.1.1.2).
–If the DHCP server is running on a Linux platform, set the tftp-server-name option.
Note This solution has worked on all machines on which it has been tried, but it has not been officially tested.

Technical Assistance Center
The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.
Cisco TAC inquiries 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.
The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.
Cisco TAC Web Site
You can use the Cisco TAC Web Site 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 this URL:
All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site.
