Re: iSCSI: Request to change Logout Request

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

I have looked into it and unfortunately we can't keep everything everywhere
in place.

CID is bytes 20-21 in Login and Logout (so that the TTT place can't be kept
everywhere).

We could move the reason (function) in byte 1 (as it is in most requests).

If nobody shouts loudly against this we might do move reason (function)
into byte 1

Hello Julian,

Can I make a request to change the position of the field "Reason code"
in
the Logout Request from offset 23 to 3.
This change would make the PDU consistent with others and make decoding
simpler as most PDUs have fields "Reason" or "Response" at offset 3.

As you know offsets 20-23 are usually used for "Target Transfer Tag",
except
"Expected Data Transfer Length" in the SCSI command (it have no reserved
fields) and "CID" for Login/Logout requests. I think that "CID" could be
placed e.g. at offset 40 as an "additional" parameter.


Regards,

    Jarda
