In a dynamic configuration, you only need to specify that the system’s IP address and target/initiator information
are 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 Table 17.
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.
Notes:
• 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:
