The thing is that it is not documented what the -P option actually does. Apparently it slightly changes the output format of discover and node modes when nonzero but prints gobs of information in session mode when nonzero and even more when it is 2 or3. So I would really appreciate a short note in the man page what value of P selects what information in what mode like: When non-zero the output in discovery, node or session mode is printed in tree-like format. In session mode 1 prints interfaces 2 also prints parameters and 3 also prints devices. Thanks Michal -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
