3. Map the virtual disk to the iSCSI target created in step 1.
4. Associate an iSCSI initiator with the iSCSI target.
5. Record the iSCSI target name, TCP port number, iSCSI Logical Unit Number (LUN), initiator Internet
Qualified Name (IQN), and CHAP authentication details.
6. After configuring the iSCSI target, obtain the following:
• Target IQN
• Target IP address
• Target TCP port number
• Target LUN
• Initiator IQN
• CHAP ID and secret
Configuring iSCSI Boot Parameters
Configure the Broadcom iSCSI boot software for either static or dynamic configuration. Refer to Table 17 for
configuration options available from the General Parameters screen.
Table 17 lists parameters for both IPv4 and IPv6. Parameters specific to either IPv4 or IPv6 are noted.
Note: Availability of IPv6 iSCSI boot is platform/device dependent.
Table 17: Configuration Options
Option Description
TCP/IP parameters via DHCP This option is specific to IPv4. Controls whether the iSCSI boot host software
acquires the IP address information using DHCP (Enabled) or use a static IP
configuration (Disabled).
IP Autoconfiguration This option is specific to IPv6. Controls whether the iSCSI boot host software
will configure a stateless link-local address and/or stateful address if DHCPv6
is present and used (Enabled). Router Solicit packets are sent out up to three
times with 4 second intervals in between each retry. Or use a static IP
configuration (Disabled).
iSCSI parameters via DHCP Controls whether the iSCSI boot host software acquires its iSCSI target
parameters using DHCP (Enabled) or through a static configuration
(Disabled). The static information is entered through the iSCSI Initiator
Parameters Configuration screen.
CHAP Authentication Controls whether the iSCSI boot host software uses CHAP authentication
when connecting to the iSCSI target. If CHAP Authentication is enabled, the
CHAP ID and CHAP Secret are entered through the iSCSI Initiator
Parameters Configuration screen.
DHCP Vendor ID Controls how the iSCSI boot host software interprets the Vendor Class ID field
used during DHCP. If the Vendor Class ID field in the DHCP Offer packet
matches the value in the field, the iSCSI boot host software looks into the
DHCP Option 43 fields for the required iSCSI boot extensions. If DHCP is
disabled, this value does not need to be set.
