DHCP iSCSI Boot Configurations for IPv4
DHCP includes a several options that provide configuration information to the
DHCP client. For iSCSI boot, QLogic adapters support the following DHCP
configurations:
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>"
lists the DHCP Option 17 parameters.
