3 Select Primary Boot Device Settings.
a Enter the discovery Target IP and Target Port.
b Configure the Boot LUN and iSCSI Name parameters.
n
If only one iSCSI target and one LUN are available at the target address, leave Boot LUN
and iSCSI Name blank.
After your host reaches the target storage system, these text boxes are populated with
appropriate information.
n
If more than one iSCSI target and LUN are available, supply values for Boot LUN and iSCSI
Name.
c Save changes.
4 From the iSCSI Boot Settings menu, select the primary boot device.
An auto rescan of the HBA finds new target LUNs.
5 Select the iSCSI target.
If more than one LUN exists within the target, you can select a specific LUN ID by pressing Enter
after you locate the iSCSI device.
6 Return to the Primary Boot Device Setting menu. After the rescan, Boot LUN and iSCSI Name are
populated. Change the value of Boot LUN to the appropriate LUN ID.
iBFT iSCSI Boot Overview
ESXi hosts can boot from an iSCSI SAN using the software or dependent hardware iSCSI adapters and
network adapters.
To deploy ESXi and boot from the iSCSI SAN, the host must have an iSCSI boot capable network
adapter. The adapter must support the iSCSI Boot Firmware Table (iBFT) format, a method of
communicating parameters about the iSCSI boot device to an operating system.
Before installing ESXi and booting from the iSCSI SAN, configure the networking and iSCSI boot
parameters on the network adapter. Because configuring the network adapter is vendor-specific, review
your vendor documentation for instructions.
When you boot from iSCSI for the first time, the iSCSI boot firmware on your system connects to an iSCSI
target. If a login is successful, the firmware saves the networking and iSCSI boot parameters in the iBFT
and stores the table in the system's memory. The system uses this table to configure its own iSCSI
connection and networking and to start up.
The following list describes the iBFT iSCSI boot sequence.
1 When restarted, the system BIOS detects the iSCSI boot firmware on the network adapter.
2 The iSCSI boot firmware uses the preconfigured boot parameters to connect with the specified iSCSI
target.
