Introduction

The Cisco Storage Networking iSCSI Driver for Microsoft Windows 2000 provides a server 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 server and a Cisco SN 5420 Storage Router.

Architecturally, the iSCSI driver combines with the server TCP/IP stack, network drivers, and NICs to provide the same functions as a SCSI 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 server and a Cisco SN 5420 Storage Router via an IP network. The SN 5420 Storage Router, in turn, transports SCSI requests and responses between it and the storage devices attached to it.

Once the iSCSI driver is installed, the server will proceed with a discovery process for iSCSI storage devices as follows:


Step 1 The iSCSI driver requests available iSCSI targets from the storage router.

Step 2 The storage router sends available iSCSI target names to the server.

Step 3 The server logs into the iSCSI targets.

Step 4 The storage router accepts the server login and sends target identifiers.

Step 5 The server queries targets for device information.

Step 6 Targets respond with device information.

Step 7 The server creates table of internal devices.


The Cisco Storage Networking iSCSI Driver for Microsoft Windows 2000 provides IP access to a maximum of eight remote SCSI targets, with each target capable of supporting eight LUNs. Remote SCSI targets can be accessed through one or more storage routers up to a maximum of eight storage routers.


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

This section describes the system requirements for version 1.8.8 and includes the following information:

Operating System Requirements

Obtaining the iSCSI Driver

Determining the iSCSI Driver Version

Uninstalling iSCSI Driver Software

Operating System Requirements

The Cisco Storage Networking iSCSI Driver for Microsoft Windows 2000 requires Microsoft Windows 2000 Professional or Server with service pack 2 or higher. If service pack 2 is installed, Microsoft hotfix Q302895 is required. This fix does not appear on the Microsoft hotfix web site; you must specifically request it. This fix will eventually be bundled into Microsoft Windows 2000 service pack 3.


Note If you are running Microsoft Windows 2000 Professional or Server with service pack 1, you must upgrade to service pack 2 and apply the Microsoft hotfix Q302895.


To obtain hotfix Q302895, call Microsoft customer support at 1-800-936-4900 (or any Microsoft customer support phone number) and request the hotfix for Knowledge Base (KB) article Q302895. You will be asked to supply an e-mail address. You will receive an e-mail message with a link to an FTP site where you can download the hotfix. The e-mail message will also contain a password that you will be prompted to enter when you open the hotfix file.

For additional information about the hotfix, access the Microsoft website at http://www.microsoft.com and follow the support link to view KB article Q302895.


Note This driver will not work with computers running Microsoft Windows NT.

Determining the iSCSI Driver Version

To determine the version of the iSCSI driver software installed on your server, open Control Panel and double-click the iSCSI Config icon. The lower left corner of the dialog box shows the version number of the iSCSI Config program and the title bar shows the operating system it is intended for. Click Status to show the version information of the iSCSI driver on the top line.

You can also verify version information by checking the file versions of these files:

iscsi.sys

iscsicfg.cpl

Follow these steps:


Step 1 Use Windows Explorer to navigate to the c:\winnt\system32\drivers directory.

Step 2 Right-click the file iscsi.sys and then click Properties from the shortcut menu. The Properties dialog box displays.

Step 3 Click the Version tab, and check the File version.

Step 4 Navigate to the c:\winnt\system32\ directory.

Step 5 Right-click the file iscsicfg.cpl and then click Properties from the shortcut menu. The Properties dialog box displays.

Step 6 Click the Version tab, and check the File version. The file version information should be the same in both files.


Uninstalling iSCSI Driver Software

Follow these steps to uninstall iSCSI driver software:


Step 1 Run the setup.exe executable for the currently installed iSCSI driver to start the installation program.

Step 2 Follow the on-screen instructions to remove the iSCSI driver software.
