Re: iSCSI: question and wording of Reject

["Julian Satran" <Julian_Satran@il.ibm.com>]

Dennis,

I will take a look at all occurrences of "reject" and add PDU when
required.
As for the original question - a text request the is the "command" and no
other response is due.
The response due was meant for exchanges that involve other type of PDUs -
e.g., a SCSI request that is followed by data - if you reject a data
or SNACK you are still required to send the response.

Does a target need to send a Text Response after it has sent a Reject for
the
Text Request?  The 2nd sentense in sec 6.2 says a Text Response PDU must
be returned, but the 3rd sentense seems to be conflicting.  Please clarify.


  on page 85 (draft 13):
      A target may reset an operational parameter negotiation by answering
a

      Text request with a Reject.

  on page 105:
    6.2  Usage Of Reject PDU in Recovery
      Targets MUST NOT implicitly terminate an active task by sending a
      Reject PDU for any PDU exchanged during the life of the task.  If the

      target decides to terminate the task, a Response PDU (SCSI, Text,
      Task etc.) must be returned by the target to conclude the task.  If
      the task had never been active before the Reject (i.e., the Reject is

      on the command PDU), targets should not send any further responses
      because the command itself is being discarded.

In general, the word "Reject" is pretty overloaded, it would be more clear
to explicitly say "Reject PDU" for all situations that refer to the Reject
PDU.
Here are some of those situations:

    "Reject" in 2nd paragraph on page 85;
    "Reject" in 3rd paragraph on page 85;
    "Reject" in sec 6.9 page 110;
    "Reject" in 2nd paragraph on page 160;
    "Reject" in 1st paragraph on page 172;

"Login Reject" on page 79: there is no reason code called "Login Reject",
maybe the word Reject should be changed to lower case, to be consistent
with the other occurances of "Login reject".

Thanks,
Dennis
