DHCP Server Configuration: Intel® Ethernet iSCSI Boot User
Guide
If you are using Dynamic Host Configuration Protocol (DHCP), the DHCP server needs to be configured to provide the iSCSI
Boot configurations to the iSCSI initiator. It is necessary to set up the DHCP server to specify Root Path option 17 and Host
Name option 12 in responding iSCSI target information back to the iSCSI initiator. DHCP option 3, router list may be
necessary, depending on the network configuration.
NOTE: Conflict detection should be enabled on the DHCP server.
DHCP Root Path Option 17:
The iSCSI root path option configuration string uses the following format:
ISCSI:::::
Examples:
iscsi:192.168.0.20:6:3260:0:iqn.1986-03.com.intel:target1
Server name: iSCSI server name or valid IPv4 address literal. Example: 192.168.0.20.
Protocol: Transport protocol used by ISCSI. Default is TCP (6). No other protocols are currently
supported.
Port: Port number of the iSCSI target. A default value of 3260 will be used if this field is left blank.
LUN: LUN ID configured on iSCSI target system. The LUN value entered should be in hexadecimal. For
example, an LUN ID of 64 (decimal) would be configured as 40 (hexadecimal). Default is zero.
Target name: iSCSI target name to uniquely identify an iSCSI target in IQN format.
Example: iqn.1986-03.com.intel:target1
DHCP Host Name Option 12:
Configure option 12 with the hostname of the iSCSI initiator.
DHCP Option 3, Router List:
Configure option 3 with the gateway or router IP address, if the iSCSI initiator and iSCSI target are on different subnets.
