Re: iSCSI: Connection termination conditions

["Mallikarjun C." <cbm@rose.hp.com>]

Nandakumar,

As the preceding sentence indicates, the "graceful connection 
shutdown" being referred to is the TCP connection termination.

All the text is saying is that the an intentional and graceful 
transport connection termination must also be "graceful" wrt iSCSI.  
The first sentence in this section requires rewording for rev10, 
and I suggest ignoring it for now.

Thanks.
