Configuring the DHCP Server to Support iSCSI Boot
The DHCP server is an optional component, and is only necessary if you will be
doing a dynamic iSCSI boot configuration setup (see “Dynamic iSCSI Boot
Configuration” on page 82).
Configuring the DHCP server to support iSCSI boot differs for IPv4 and IPv6:
 DHCP iSCSI Boot Configurations for IPv4
 Configuring the DHCP Server
 Configuring DHCP iSCSI Boot for IPv6
 Configuring vLANs for iSCSI Boot
DHCP iSCSI Boot Configurations for IPv4
DHCP includes several options that provide configuration information to the
DHCP client. For iSCSI boot, Marvell FastLinQ adapters support the following
DHCP configurations:
 DHCP Option 17, Root Path
 DHCP Option 43, Vendor-specific Information
DHCP Option 17, Root Path
Option 17 is used to pass the iSCSI target information to the iSCSI client.
The format of the root path, as defined in IETC RFC 4173, is:
"iscsi:"<servername>":"<protocol>":"<port>":"<LUN>":"<targetname>"
Table 6-3 lists the DHCP Option 17 parameters.
Table 6-3. DHCP Option 17 Parameter Definitions
Parameter Definition
"iscsi:" A literal string
<servername> IP address or fully qualified domain name (FQDN) of the iSCSI
target
":" Separator
<protocol> IP protocol used to access the iSCSI target. Because only TCP is
currently supported, the protocol is 6.
<port> Port number associated with the protocol. The standard port num-
ber for iSCSI is 3260.
