Setup 12
DHCP iSCSI boot configuration for IPv6
The DHCPv6 server provides a number of options, including stateless or stateful IP configuration, and
information to the DHCPv6 client. For iSCSI boot, HP FlexFabric adapters support these DHCP
configurations:
• DHCPv6 option 16, vendor class option (on page 12)
• DHCPv6 option 17, vendor-specific information (on page 12)
The DHCPv6 standard root path option is not available. Use 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 the
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 sub-options are provided that assign the initiator IQN to the iSCSI boot
client along with two iSCSI target IQNs that are used for booting.
Sub-option Definition
201
First iSCSI target information in the standard root path format:
"iscsi:"[<servername>]":"<protocol>":"<port>":"<LUN>":"<targetname>"
202
Second iSCSI target information in the standard root path format:
"iscsi:"[<servername>]":"<protocol>":"<port>":"<LUN>":"<targetname>"
203
iSCSI initiator IQN
Brackets [ ] are required for the IPv6 addresses. The content of option 17 is <2-byte Option Number
201|202|203> <2-byte length> <data>.
Configuring the DHCPv6 server
Configure the DHCP server to support option 16 and option 17.
The format of DHCPv6 option 16 and option 17 are fully defined in RFC 3315.
Preparing the iSCSI boot image
To prepare the iSCSI boot image:
• Windows Server 2008 R2 and SP2 iSCSI boot setup (on page 13)
• Windows Server 2012 iSCSI boot setup (on page 14)
• Linux iSCSI boot setup (on page 14)
• Injecting (slipstreaming) Broadcom drivers into Windows image files (on page 17)
