ISCSI BOOT SETUP
The iSCSI boot setup consists of:
• Configuring the iSCSI Target
• Configuring iSCSI Boot Parameters
• Preparing the iSCSI Boot Image
• Booting
Configuring the iSCSI Target
Configuring the iSCSI target varies by target vendors. For information on configuring the iSCSI target, refer to the
documentation provided by the vendor. The general steps include:
1. Create an iSCSI target.
2. Create a virtual disk.
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 1 for configuration
options available from the General Parameters screen.
Table 1 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 1: 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).
