Enable iSCSI boot and set the boot order

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.

  1. During the initial boot phase, press <F9> to enter the RBSU.
  2. At the RBSU menu, select System Options.
  3. At the System Options menu, select the embedded adapter.
  4. Select Network boot (for G6 and later servers) or iSCSI boot. HP recommends that PXE be disabled on unused ports to conserve option ROM space.
  5. Press <Esc> to exit the RBSU.

Mezzanine and Standup adapters. The iSCSI boot option ROM is enabled interactively at the console.

  1. During the initial boot phase, press <Ctrl-S> when prompted to display the MBA Configuration Menu.
  2. Verify that iSCSI is selected for the Boot Protocol entry.
  3. Press <F4> to save the changes and then press <Esc> to exit the MBA configuration menu.

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.

  1. During the initial boot phase, press <F9> to enter the RBSU.
  2. At the RBSU menu, select Standard Boot Order (IPL).
  3. Verify that the iSCSI boot adapter is listed first in the IPL list. Modify the boot order, if necessary.
  4. Press <Esc> to exit the RBSU.
