DHCP Option 17, Root Path
DHCP option 17 specifies the path name that contains the client’s root disk. The
path is formatted as a character string consisting of characters from the network
virtual terminal (NVT) ASCII character set. The data is formatted as a string using
the DHCP Root Path Option (Option 17):
"iscsi:"<servername | serveripaddress>":"<protocol>":"<port>":
"<LUN>":"<targetname>"
DHCP Option 43 (Adding Vendor Options)
Define a vendor class called "QLogic" as part of the "Default User Class," and
then add the iSCSI specific information. Two of these options—201 and
202—contain iSCSI boot target information for primary and secondary targets,
respectively. BIOS must parse the Vendor Specific Information buffer for the
Primary Boot Target (Option 201). The third option, iSCSI Initiator (Option 203),
contains the iSCSI initiator IQN information.
