I'm porting an application which runs on OpenIndiana. In OpenIndiana,
we just invoke itadm and stmfadm to create and destroy ISCSI targets.
The command targetcli, however, seems a bit unfriendly to scripting in
this fashion, seeing how it's interactive and all.
I found this patch, and applied it, and it's allowed me to invoke
targetcli as a one-liner, like:
targetcli /iscsi create iqn.a.b.c:x
Unfortunately, if the command fails, the exit code is still always 0.

But forget my approach for a second--I feel I might be missing how
this is usually done. Does anyone script using targetcli, or do they
use some other command instead?
This is a longtime issue with targetcli. Errors are not propagated all
the way up to a single place that would make exiting with an error code
possible. Alternatives include:
1) Poking configfs yourself, directly or with lio-utils
2) If using Python, using rtslib library
if using targetcli-fb:
3) reading/modifying/writing /etc/target/saveconfig.json then reloading
config
4) cmdline invocation with that patch you referenced
with another possibility of course being:
5) Fix targetcli
