Typically all you need to do is add the following to /boot/loader.conf after= installing the isboot port: isboot_load=3D"YES=E2=80=9D =46rom there it=E2=80=99s up to the boot firmware (iPXE in your case) to mak= e the initial connection to the target, populate the iBFT, load the boot blo= cks and perform the early boot.

I have tried to boot over iSCSI using PXE using the ports isboot-kmod. I= t worked after many tries, but it is not automatic yet.

At the loader.efi prompt I do:
set currdev=3Dzf= s:zroot/ROOT/default:
load /boot/kernel/kernel
load /boot/kernel/opensolaris.ko
load /boot/kernel/zfs.ko=
load /boot/kernel/acpi_wmi.ko
load /boot/ke= rnel/smbus.ko
load /boot/kernel/ichsmb.ko
lo= ad /boot/kernel/uhid.ko
load /boot/kernel/wmt.ko
<= span>load /boot/kernel/iscsi.ko
load /boot/modules/isboot.ko=
boot

And it starts. There i= s no local storage so everything is really coming over the net.

Obviously it doesn=E2=80=99t read what is in loader.con= f and I=E2=80=99m puzzled what the boot flow is once you have loader.efi loa= ded. I can put currdev in loader.env but it doesn=E2=80=99t set it although s= et qqq=3Dsomething shows up when I type show, so I have the right file.

How can I boot without having to type the comma= nds?

Typically all you need to d= o is add the following to /boot/loader.conf after installing the isboot port= :

isboot_load=3D"YES=E2=80=9D
<= span style=3D"caret-color: rgb(5, 5, 5); color: rgb(5, 5, 5); font-family: v= ar(--code-font); font-size: 12.75px;">
=46rom there it=E2= =80=99s up to the boot firmware (iPXE in your case) to make the initial conn= ection to the target, populate the iBFT, load the boot blocks and perform th= e early boot. The loader uses the iSCSI disk just like a local disk to do it= s job including load the kernel and modules (including isboot) in to memory.=

When the kernel begins execution it probes devices= and eventually gets to isboot. If isboot locates a valid iBFT it will parse= it and use that information to re-establish the connection with the iSCSI t= arget (as well as bring up the needed network interface etc).

=
=46rom there the iSCSI volume(s) should be available as regular d= a(4) devices and boot continues like it would on any other type of storage.<= /div>

The root volume being ZFS adds some moving parts bu= t there=E2=80=99s no reason it wouldn=E2=80=99t work. If you can, try to rep= licate your setup using local storage. Once that is working then you just ne= ed to add iPXE and the single line above to loader.conf.
