Introduction
The iSCSI Driver for Microsoft Windows 2000 provides an IP host with the ability to access storage through an IP network. The iSCSI driver uses iSCSI protocol to transport SCSI requests and responses over an IP network between the host and a Cisco SN 5400 Series system.
Architecturally, the iSCSI driver combines with the host TCP/IP stack, network drivers, and NICs to provide the same functions as a SCSI or a Fibre Channel adapter driver with a host bus adapter (HBA).
The iSCSI driver provides a transport for SCSI requests and responses for storage devices; however, instead of providing a transport for directly attached devices, the driver transports the SCSI requests and responses between the IP host and a Cisco SN 5400 Series system via an IP network. The SN 5400 Series system, in turn, transports SCSI requests and responses between it and the storage devices attached to it.
Once the iSCSI driver is installed, the IP host will proceed with a discovery process for iSCSI storage devices as follows:
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
The iSCSI Driver for Microsoft Windows 2000 provides IP access to a maximum of eight remote SCSI targets, with each target capable of supporting 255 LUNs. Remote SCSI targets can be accessed through one or more SN 5400 Series systems up to a maximum of eight SN 5400 Series systems.

New and Changed Information
The iSCSI driver version 2.2.1 supports Cisco Network Boot, 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.
For more information on Cisco Network Boot, refer to the Cisco Network Boot Installation and Configuration Guide Release 2.1 and the associated release notes document. These documents are available as electronic document on Cisco.com and the Documentation CD-ROM.
Caveats
Caveats describe unexpected behavior or defects in iSCSI software versions. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

Open Caveats
•
If the PXE NIC configuration is changed to DHCP or to an incorrect IP address after replication, the computer cannot be rebooted to correct the error. The computer hangs on the boot process.
Workaround: Use the Network Boot Administration Utility to overwrite the volume by replicating the original master volume. All data on the LUN will be lost. If there is data on the LUN that must be saved, access the LUN from another iSCSI client and backup the critical data.
Note
Resolved Caveats
There are no severity 1 or 2 caveats resolved against the iSCSI driver version 2.2.1. 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.
