Broadcom suggests using Option 16 or Option 17 for dynamic iSCSI Boot IPv6 support. DHCPv6 Option 16, Vendor Class Option DHCPv6 Option 16 (vendor class option) must be present and must contain a string that matches your configured DHCP Vendor ID parameter. The DHCP Vendor ID value is BRCM ISAN, as shown in General Parameters of the iSCSI Boot Configuration menu. The content of Option 16 should be . DHCPv6 Option 17, Vendor-Specific Information DHCPv6 Option 17 (vendor-specific information) provides more configuration options to the iSCSI client. In this configuration, three additional suboptions are provided that assign the initiator IQN to the iSCSI boot client along with two iSCSI target IQNs that can be used for booting. The suboptions are listed below.

DHCPv6 Option 16, Vendor Class Option
DHCPv6 Option 17, Vendor-Specific Information
NOTE: The DHCPv6 standard Root Path option is not yet available. Broadcom suggests using Option 16 or Option 17
for dynamic iSCSI Boot IPv6 support.
DHCPv6 Option 16, Vendor Class Option
DHCPv6 Option 16 (vendor class option) must be present and must contain a string that matches your configured
DHCP
Vendor ID
parameter. The
DHCP Vendor ID
value is BRCM ISAN, as shown in
General Parameters
of the iSCSI Boot
Configuration menu.
The content of Option 16 should be <2-byte length> <DHCP Vendor ID>.
DHCPv6 Option 17, Vendor-Specific Information
DHCPv6 Option 17 (vendor-specific information) provides more configuration options to the iSCSI client. In this configuration,
three additional suboptions are provided that assign the initiator IQN to the iSCSI boot client along with two iSCSI target
IQNs that can be used for booting.
The suboptions are listed below.

NOTE: In
Table 4
, the brackets [ ] are required for the IPv6 addresses.
The content of option 17 should be <2-byte Option Number 201|202|203> <2-byte length> <data>.
Configuring the DHCP Server
Configure the DHCP server to support Option 16 and Option 17.
NOTE:
The format of DHCPv6 Option 16 and Option 17 are fully defined in RFC 3315.

Windows Server 2008 R2 and SP2 iSCSI Boot Setup
The Windows Server 2008 R2 and the Windows Server 2008 SP2 support booting as well as installing in either the offload or
non-offload paths.
The following procedure is to prepare to install and boot the Windows Server 2008 R2 and SP2 iSCSI Boot image in either the
offload or non-offload path. The procedure below references the Windows Server 2008 R2 but procedure is common to both
the Windows Server 2008 R2 and SP2.
