iSCSI: Connection termination conditions

["Nandakumar Ramamurthy" <nramamur@npd.hcltech.com>]

Hi All,

Section 2.2.6 specifies two conditions for connection termination :

"Graceful connection shutdowns MUST only occur when there are no
 outstanding tasks that have allegiance to the connection and when the
connection is not in full-feature phase."

The above statement is ambiguous as to what a graceful connection
shutdown is and the conditions in which this may occur. Can "graceful
connection shutdown" be elaborated upon?

My interpretation is that there could be 2 possible cases when graceful
connection termination may occur. They are as follows:

1) A connection logout with no outstanding allegiant tasks is the first
condition.
In this case, the state of the connection is full feature.

2) The second case is when the connection is shutdown and the connection
state is not in full feature phase i.e., in SecurityNegotiation or
LoginOperationalNegotiation
phase.

Is that the correct interpretation?

Thanks,
