iSCSI 07-95 Comments 14 Through 19

[Thomas Dineen <tdineen@redswitch.com>]

Gentle People:

First of all I would like to commend the author of the
state machines. I believe that addition of the state machines
to the document substantially enhances the overall conciseness.

Several comments regarding 07-95 section 7 starting on page 118:

14) In Sections 7.1, 7.2, 7.3 I would suggest enhancing
the description of each state and each state transition.
After reading this section carefully I have concluded that
additional text would be of great benefit. Please provide
a few sentences or a paragraph describing each state and
each state transition.

15) The state transition descriptions would be improved by
linking the logical conditions to those of a TCP Service Interface
such as Sockets. I am looking for a more formal and concise
definition of each of the referenced logical conditions.

16) In several places I see the term "[OR}" what dose this mean
exactly a simple "or"?

17) In section 7.3 transition N6 a session state time-out is referenced.
where is this timer and time-out defined?

18) In section 7.2:

"These additional state transitions may be traversed either by using a
connection in the LOGGED_IN state with an explicit logout (let us
call it CSM-E), or on a new transport connection in the FREE state
with an implicit logout (let us call it CSM-I). This recovery state
diagram hence is applicable only to the instance of the connection in
recovery, i.e. CSM-R."

From what I can tell you are trying to recover a failed connection
using the communication services of another existing or newly
established
connection. Please add a few sentences or a paragraph describing this
concept fully.

19) In section 7.1 and the following sections:

"T7: A login redirection/initiator error/target error was
received, or login timed out. (Initiator only)"

In this statement the "/" is used repeatedly: Dose "/"
really mean "or"?

So the statement could read:
"T7: A login redirection, initiator error, or target error was
received, or the login timed out. (Initiator only)"

If you mean "or" why not use 'or"?

20) Referring to T7 above, where is the Login timer specified?
