It is recommended to always run iscsibcg.exe /verify /fix at a command prompt after updating the driver and before restarting the system. For information on configuring the iscsibcg utility to run automatically when a system shuts down, see http://support.microsoft.com/kb/934235. Transferring the OS Image to the iSCSI Target 1. Create a new FAT32 partition on the local hard drive using the disk management console. 2. Boot to a bootable device such as a diskette drive, media, or USB key and run a disk imaging software, such as Symantec Ghost. 3. Clone the OS partition to the FAT32 partition (partition to image). 4. Place the iSCSI boot adapter before the hard drive in the boot menu. 5. Reboot the host and boot into the OS in the local hard drive. 6. Launch Windows compatible cloning software, such as Ghost32, and write the image in the FAT32 partition to the remote LUN. Booting After that the system has been prepared for an iSCSI boot and the operating system is present on the iSCSI target, the last step is to perform the actual boot. The system will boot to Windows over the network and operate as if it were a local disk drive. 1. Reboot the server. 2. Select CTRL+S and CTRL+K. 3. From the Main menu, select General Parameters and configure the Boot to iSCSI target option to Enabled. If CHAP authentication is needed, enable CHAP authentication after determining that booting is successful (see Enabling CHAP Authentication).
