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
[Fred]: I tried. It seems it did not work.
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.
[Fred]: It works well!
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.
[Fred]: Are there comprehensive documents about all the parameters fed to
kernel? Could the alternative way be
Adding ",smartos=false,noimport=true" to the normal boot kernel?
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.
[Fred]: Hmmmmm, what is your way to restore a bad zpool like zones?
Thanks.

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.
