Yes as Phaneedra pointed out it may MaxRecvData... can change. During 
recovery one should pay attention to those changes and this is the reason 
for defining what to expect on retransmission.

iSCSI: MaxRecvDataSegmentLength changing in FFP






MaxRecvDataSegmentLength can change during Full Feature Phase (USE is 
ALL).
 
Was it the intent that it can change at any point (even in the middle of 
transmitting a sequence)?

Re: iSCSI: MaxRecvDataSegmentLength changing in FFP







Hi Eddy,

From what it is read about variable pdu lengths changing on the fly, one
has to assume the boundaries imposed can be in flux.  This may be more for
flexablitiy when dealing with target whose effective hba is a messaging
monster (FC).

Well on a side note, is there anyone testing or shipping erl2 who is
interested in compatiblity testing?

One additional side note, well question.  I assume any initiator which
issues notunderstood for standard keys exchanged is deemed a bad
initiator?  This is regardless if the ERL supported but either side.

Cheers,

Hi Eddy,
    Yes, the MaxRecvDataSegmentLength can be changed even in
the middle of the sequence transmission. And an initiator (ERL > 0)
would need to issue R-Data SNACK to request retransmission
(possibly, from the time of change in MaxRecvDataSegmentLength)
of the unacknowledged data from target, expecting resegmenation.
