George:

  I see that information from 00-335r1 has been added in 00-378r0 (SPI-4 
rev1 proposal).  Why did changing the words in para. 2 of section 
10.8.3.3.4 from:
  
  "before receiving another SPI L_Q information unit"  
  
  to:
  
  "before receiving another SPI information unit"
  
  get dropped in 00-335r1?  It was present in 00-335r0.
  
  The reason u need this change is this:  with the current wordings, it 
ONLY talks about "before RECEIVING another SPI L_Q" and only covers 
command transfers because that is the ONLY time the targer RECEIVES SPI 
L_Q IUs!  What is the target supposed to do if it detects an iuCRC error 
in a data packet that it receives during a SCSI write?  In this case, 
the TARGET is SENDING SPI L_Q IUs to the initiator NOT RECEIVING it!
  
  Also information in 10.8.3.3.3 and 10.8.3.3.4 do not address error 
handling for data stream IUs.  I can see that information in g) under 
section 12.2 (ATN condition), para 2 in 10.8.3.3.3 and para 10 in 14.3.4 
(where it mentions what to do when offset if greater than the SPI data 
stream IU size) in 00-378r0 are in conflict for error handling during 
read streaming.
  
  Please clarify.
  
  thanQ,
  Sriram

~ A proposed revision 1 of SPI-4 has been posted on the t10 web site but
~ don't look for it in the drafts section. It is document number 
00-378r0
~ titled 'Proposed content for SPI-4 rev 1'. This proposal is what the 
editor
~ recommends become SPI-4 rev 1 but because it contains some technical
~ content that was not accepted by the T10 committee it cannot be 
published
~ as an official rev 1. For a list of that technical content look in the
~ revision 1 section at items p, q, and r.
