Configuring the DHCP Server to Support iSCSI Boot
The DHCP server is an optional component and it is only necessary if you will be
doing a dynamic iSCSI Boot configuration setup (see “Dynamic iSCSI Boot
Configuration” on page 110).
Configuring the DHCP server to support iSCSI boot is different for IPv4 and IPv6.
 DHCP iSCSI Boot Configuration for IPv4
 DHCP iSCSI Boot Configuration for IPv6
DHCP iSCSI Boot Configuration for IPv4
The DHCP protocol includes a quantity of options that provide configuration
information to the DHCP client. For iSCSI boot, Marvell adapters support the
following DHCP configurations:
 DHCP Option 17, Root Path
 DHCP Option 43, Vendor-Specific Information
