With the ESX host, you can boot from the iSCSI SAN only if the host uses an independent hardware iSCSI adapter, such as QLogic HBA. You need to configure the independent hardware iSCSI adapter for booting from the SAN.

This procedure discusses how to enable the QLogic iSCSI HBA to boot from the SAN. For more information and more up-to-date details about QLogic adapter configuration settings, see the QLogic web site.

Because you first need to boot from the VMware installation media, set up your host to boot from DVD-ROM. To achieve this, change the system boot sequence in your system BIOS setup.


Insert the installation DVD in the DVD-ROM drive and reboot the host.


Use the BIOS to set the host to boot from the DVD-ROM drive first.


During server POST, press Crtl+q to enter the QLogic iSCSI HBA configuration menu.


Select the I/O port to configure.

By default, the Adapter Boot mode is set to Disable.


Configure the HBA.


From the Fast!UTIL Options menu, select Configuration Settings > Host Adapter Settings.


Configure the following settings for your host adapter: initiator IP address, subnet mask, gateway, initiator iSCSI name, and CHAP (if required).


Configure iSCSI settings.

See Configure iSCSI Boot Settings.


Save your changes and restart the system.
