provided by a DHCP server (see IPv4 and IPv6 configurations in
Configuring the DHCP Server to Support iSCSI Boot
). For
IPv4, with the exception of the initiator iSCSI name, any settings on the Initiator Parameters, 1st Target Parameters, or 2nd
Target Parameters screens are ignored and do not need to be cleared. For IPv6, with the exception of the CHAP ID and
Secret, any settings on the Initiator Parameters, 1st Target Parameters, or 2nd Target Parameters screens are ignored and do
not need to be cleared. For information on configuration options, see
NOTE: When using a DHCP server, the DNS server entries are overwritten by the values provided by the DHCP server.
This 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 configures the
appropriate registries statically. It will overwrite whatever is configured. Since the DHCP daemon runs in the Windows
environment as a user process, all TCP/IP parameters have to be statically configured before the stack comes up in the iSCSI
Boot environment.
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 screen. If no value was selected, then the controller defaults to the
name:
iqn.1995-05.com.broadcom.<11.22.33.44.55.66>.iscsiboot
where the string 11.22.33.44.55.66 corresponds to the controller's MAC address.
If DHCP option 43 (IPv4 only) is used, then any settings on the Initiator Parameters, 1st Target Parameters, or 2nd Target
Parameters screens are ignored and do not need to be cleared.
To configure the iSCSI boot parameters using dynamic configuration
1. From the General Parameters Menu screen, set the following:
TCP/IP parameters via DHCP: Enabled. (For IPv4.)
IP Autoconfiguration: Enabled. (For IPv6)
iSCSI parameters via DHCP: Enabled
CHAP Authentication: Disabled
Boot to iSCSI target: Disabled
DHCP Vendor ID: BRCM ISAN
Link Up Delay Time: 0
Use TCP Timestamp: Enabled (for some targets such as the Dell/EMC AX100i, it is necessary to enable Use
TCP Timestamp)
Target as First HDD: Disabled
LUN Busy Retry Count: 0
IP Version: IPv6. (For IPv6)
2. Select ESC to return to the Main menu.
NOTE: Information on the Initiator Parameters, and 1st Target Parameters screens are ignored and do not
need to be cleared.
3. Select Exit and Save Configurations.
Enabling CHAP Authentication
Ensure that CHAP authentication is enabled on the target.
To enable CHAP authentication
1. From the General Parameters screen, set CHAP Authentication to Enabled.
2. From the Initiator Parameters screen, type values for the following:
CHAP ID (up to 128 bytes)
CHAP Secret (if authentication is required, and must be 12 characters in length or longer)
3. Select ESC to return to the Main menu.
4. From the Main menu, select 1st Target Parameters.
