Hmm, for some reason it doesn't work for me. It did work several times however, so perhaps I'm doing something wrong. I can't find what, though.


# tgtadm --op show --mode target

Let's remove ACL permissions first (after that, "ALL" is gone from "ACL information"):

# tgtadm --op unbind --mode target --tid 3 -I ALL


Next thing would be this, I guess (Target 3 -> tid 3; I_T nexus: 11 -> sid 11; Connection: 0 -> cid 0)?

# tgtadm --op delete --mode conn --tid 3 --sid 11 --cid 0


However, it doesn't change anything:

# tgtadm --op show --mode target
(...)
