Before iSCSI boot can be used, you must first enable iSCSI boot on the adapter and then modify the boot order to select the iSCSI-enabled adapter as the boot device.
Enable iSCSI boot for HP network adapters
The iSCSI boot option ROM must be enabled before it can be used. Do not enable iSCSI boot on more than two adapters because option ROM space is limited and it may cause the iSCSI boot to fail.
The following sections describe how to enable iSCSI boot on embedded, mezzanine, and standup adapters.
Embedded adapters. The iSCSI boot option ROM is enabled on embedded adapters by using the RBSU tool that is built into the system ROM.
Mezzanine and Standup adapters. The iSCSI boot option ROM is enabled interactively at the console.
Set the boot order to boot from the iSCSI adapter
The iSCSI-enabled adapter must be listed first in the Standard Boot Order (IPL) list.
