Dynamic iSCSI boot configuration
For a dynamic configuration, specify the system IP address. The target and initiator information are provided
by a DHCP server. For more information, see the IPv4 and IPv6 configurations in "Configuring the DHCP
Server to Support iSCSI Boot (on page
)." 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 "Configuration options (on page
)."
IMPORTANT:
When using a DHCP server, the DNS server entries are overwritten by the values
provided by the DHCP server.
Overwriting the DNS server entries with the values provided by the DHCP server 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. iSCSI initiator overwrites whatever is configured. Because 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 following 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 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, configure these options:
o
TCP/IP parameters via DHCP: Enabled (for IPv4)
o
IP Autoconfiguration: Enabled (for IPv6, non-offload)
o
iSCSI parameters via DHCP: Enabled
o
CHAP Authentication: Disabled
o
DHCP Vendor ID: BRCM ISAN
o
Link Up Delay Time: 0
o
Use TCP Timestamp: Enabled
