SYMPTOMS

Consider the following scenario:

• You are running a Windows Server 2008-based computer.
• You establish an iSCSI session on this computer.
• In the iSCSI session, you click to select the Automatically restore this connection when computer starts check box.

After you restart the computer, you expect the Microsoft Software Initiator to automatically log on and to make the logical unit numbers (LUNs) available without requiring you to manually create an iSCSI session. However, this feature may not work as expected if you are using Challenge Handshake Authentication Protocol (CHAP) authentication.

CAUSE

This problem may occur because the encrypted CHAP secret may be corrupted in memory after it is read from the registry on a Windows Server 2008-based computer.

MORE INFORMATION

Users and applications request and receive data from high-performance data storage devices over standard network switches and over IP routers. The iSCSI protocol sends SCSI commands that are encapsulated in IP packets over TCP/IP networks. Because iSCSI is IP-based, data can be transmitted over local area networks (LANs), over wide area networks (WANs), and over the Internet to remote storage locations.
