All:

At the URL below, please find a table describing the 
"clearing effects" of various events on an iSCSI 
target's protocol variables and/or states.  I was
prompted by some online and offline requests suggesting 
a table like this, this is generally similar to 
FCP-2's table with the same name.  I propose to 
incorporate this into the iSCSI main draft - ERT 
had already reviewed this.  

The only downside I can see is that it introduces some
(minor) redundancy, but I believe that the interoperability
benefits (that this brings about) would greatly outweigh 
this disadvantage. 

The URL is:

   http://storage-arch.hp.com/clearing_effects.pdf

- There are several footnotes in the table that detail
  the reasoning.  I would like to draw your attention to 
  one specific note (19).  This points out that the SCSI
  persistent reservations are released (if the SCSI APTPL
  bit was not used in securing the reservations) on a 
  target cold reset - IOW, cold reset is identical to 
  a powercycle in all protocol aspects.

- Sorry for the acronyms for the column names (than rotating
  the full name to be vertical in the cell), that was done 
  keeping in mind the eventual need to translate this 
  into ASCII.  All the acronyms have footnotes describing
  them.

Comments are welcome.
