iSCSI Boot
Broadcom NetXtreme II Gigabit Ethernet adapters support iSCSI boot to enable network boot of operating systems to diskless
systems. iSCSI boot allows a Windows, Linux, or VMware operating system boot from an iSCSI target machine located
remotely over a standard IP network.
For both Windows and Linux operating systems, iSCSI boot can be configured to boot with two distinctive paths: non-offload
(also known as Microsoft/Open-iSCSI initiator) and offload (Broadcom's offload iSCSI driver or HBA). Configuration of the
path is set with the HBA Boot Mode option located on the General Parameters screen of the iSCSI Configuration utility.
See
Table 1 for more information on all General Parameters screen configuration options.
Supported Operating Systems for iSCSI Boot
The Broadcom NetXtreme II Gigabit Ethernet adapters support iSCSI boot on the following operating systems:
Windows Server 2008 and later 32-bit and 64-bit (supports offload and non-offload paths)
Linux RHEL 5.5 and later, SLES 11.1 and later (supports offload and non-offload paths)
SLES 10.x and SLES 11 (only supports non-offload path)
iSCSI Boot Setup
The iSCSI boot setup consists of:
Configuring the iSCSI Target
Configuring iSCSI Boot Parameters
Preparing the iSCSI Boot Image
Booting
Configuring the iSCSI Target
Configuring the iSCSI target varies by target vendors. For information on configuring the iSCSI target, refer to the
documentation provided by the vendor. The general steps include:
1. Create an iSCSI target.
2. Create a virtual disk.
3. Map the virtual disk to the iSCSI target created in step 1.
4. Associate an iSCSI initiator with the iSCSI target.
5. Record the iSCSI target name, TCP port number, iSCSI Logical Unit Number (LUN), initiator Internet Qualified Name
(IQN), and CHAP authentication details.
6. After configuring the iSCSI target, obtain the following:
Target IQN
Target IP address
Target TCP port number
Target LUN
