If you know the mac address of the NIC you want to bring online, you can
edit the kernel command line within grub and append the following stuff:
,admin_mac=11:22:33:44:55:66,admin_ip=dhcp
or
,admin_mac=11:22:33:44:55:66,admin_ip=192.168.x.y,admin_netmask=255.255.255.0,admin_gateway=192.168.x.1
If you can't edit the kernel command line, the alternative to getting
the system to finish coming up is to manually create the /usbkey
directory, and create a minimal /usbkey/config file with the networking
configuration you want. After that "sysinfo -f" then "svcadm clear
network/physical" and the system should finish bringing services online.
You'll probably need to fix up /etc/resolv.conf if you want to make
outbound connections.
Be aware that you're bringing the machine online with a known root
password that will work over SSH. You can replace the hash in the kernel
command line with something else if you want to be extra cautious.
I hope that helps.
To answer your original question about why there isn't a rescue mode
that includes networking, I think the main reasons are:
1. SmartOS is often used on machines with multiple NICs. There's no way
to know which to use without more information from the operator.
2. SmartOS is often used on networks with no DHCP server. Without being
told what IP address to use there would be no way for SmartOS to
configure working networking.
3. The system would then come online with a known root password and SSH
running and that could be dangerous.
4. In light of those other reasons, no one has written code for it.

Yeah. That is doable. But because there is no zpool imported,
network/physical can’t be started. And a lot of protocols can’t run
neither.
Thanks.

You can use ifconfig to bring it up manually.
ifconfig e1000g0 inet auto-dhcp (from memory so it may be incorrect)

Hi,
“noinstall/recovery” is really helpful to fix/save zpools. But it
is offline. Is it hard to enable networking in it? Just like
“fail-safe-mode-with-network”.
Nobody wants to recover from remote backup but that is the ideal life.
Thanks.
