For information on configuration options, see

If DHCP option 17 is used, the target information is provided by the DHCP server
and the initiator iSCSI name is retrieved from the value programmed from the
Initiator Parameters window. If no value was selected, the controller defaults to
the following name:
iqn.1995-05.com.qlogic.<11.22.33.44.55.66>.iscsiboot
The string
11.22.33.44.55.66
corresponds to the controller’s MAC address. If
DHCP option 43 (IPv4 only) is used, any settings on the following windows are
ignored and do not need to be cleared:
Initiator Parameters
First Target Parameters, or Second Target Parameters
To configure the iSCSI boot parameters using dynamic configuration:
In the iSCSI General Parameters, set the following options, as shown in
TCP/IP Parameters via DHCP
: Enabled
iSCSI Parameters via DHCP
: Enabled
CHAP Authentication
: As required
IP Version
: As required (IPv4 or IPv6)
CHAP Mutual Authentication

DHCP Vendor ID
: As required
HBA Boot Mode
: Disabled
Virtual LAN ID
: As required
Virtual LAN Boot Mode
: Enabled
NOTE
When using a DHCP server, the DNS server entries are overwritten by the
values provided by the DHCP server. This override occurs even if the locally
provided values are valid and the DHCP server provides no DNS server
information. When the DHCP server provides no DNS server information,
both the primary and secondary DNS server values are set to
0.0.0.0
.
When the Windows OS takes over, the Microsoft iSCSI initiator retrieves the
iSCSI initiator parameters and statically configures the appropriate
registries. It will overwrite whatever is configured. Because the DHCP
daemon runs in the Windows environment as a user process, all TCP/IP
parameters must be statically configured before the stack comes up in the
iSCSI boot environment.
