The system will boot to Windows or Linux over the network and operate as if it were a local disk drive. 1. Reboot the server. 2. Select CTRL+S. 3. From the Main menu, select General Parameters and configure the Boot to iSCSI target option to Enabled. 4. To boot through an offload path, set the HBA Boot Mode to Enabled. To boot through a non-offload path, set the HBA Boot Mode to Disabled. If CHAP authentication is needed, enable CHAP authentication after determining that booting is successful (see Enabling CHAP Authentication). Other iSCSI Boot Considerations There are several other factors that should be considered when configuring a system for iSCSI boot. Locally Administered Address A user-defined MAC address assigned through the Locally Administered Address property of the Advanced section of the BACS Configurations tab is not supported on iSCSI boot-enabled devices. Virtual LANs Virtual LAN (VLAN) tagging is not supported for iSCSI boot with the Microsoft iSCSI Software Initiator. Troubleshooting iSCSI Boot The following troubleshooting tips are useful for iSCSI boot. Problem: When switching iSCSI boot from the Microsoft standard path to Broadcom iSCSI offload, the booting fails to complete. Solution: Install or upgrade the Broadcom Virtual Bus Device (VBD) driver to 5.0.x, along with the OIS driver, prior to switching the iSCSI boot path. Problem: The iSCSI configuration utility will not run. Solution: Ensure that the iSCSI Boot firmware is installed in the NVRAM. file:///T|/htdocs/NETWORK/BroadCom/71921/NetXtremeII/en/iscsi.htm[9/26/2012 3:29:03 PM]
