illumos gate

In my attempts to learn what could go wrong with iSCSI target and TPG creation I observed that when there is an issue with saving configuration, we could return code that is not a valid retcode. In this example I am trying to delete a valid tpg, and get a configuration error, but I think because the retcode is actually looking like a size of something than a retcode, shell is not reporting the command as a failure.

# itadm delete-tpg -f t0003; echo $?
Configuration change failed: unknown error
itadm delete-tpg failed with error 32768
0

With truss:
