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
•
DHCPv6 option 17, vendor-specific information (on page
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>
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.
