Re: Asynchronous Message: Session Termination

[Mark Bakke <mbakke@cisco.com>]

Matthew-

The intent of these was not to connect and re-establish the same
session after a set amount of time; it was to inform the initiator
not to try to establish a new session until the time passes, which
is I think what you want.  Perhaps changing the description of
#4 from:

      4    Target indicates it will/has dropped all connections - the 
      Parameter2 field indicates, in seconds, the minimum time to 
      reconnect and Parameter3 the maximum time to reconnect.

to:

      4    Target indicates it will/has dropped all connections - the 
      Parameter2 field indicates, in seconds, the minimum time to 
      wait to establish a new session and Parameter3 the maximum
      time to wait to establish a new session.

Actually, I had originally requested this, to allow a target to say
"I'm shutting down / failing over in X seconds; and will be back again
in Y seconds, so don't bother connecting until then".  With this
behavior, the description should read:

      4    Target indicates it will/has dropped all connections - the 
      Parameter2 field indicates, in seconds, the time until all
      connections will be terminated (or zero if immediately), and
      Parameter3 the maximum time the initiator should wait before
      attempting to establish a new session.

If everyone agrees with this, I would rather have the above description.
