RE: iSCSI: ImmediateData & InitialR2T

Ayman,

iSCSI connections are not separate entities. Commands are sent over a session and connection should not be visible over a certain level.  Using Immediate data belongs to a very high level layer (where the endpoint facilities are handled).
Connections should have nothing to say about it.

The text doesn't say these are connection specific, so they must be session
specific. Connection 1 logs in and doesn't send the ImmediateData key
because it wants to use the default "yes". If connection 2 sends
ImmediateData=no and the target agrees to that, how is this going to affect
connection 1 which thinks it can send immediate data, and may actually have
data in flight to the target. I think these two keys should have the same
use restrictions as DataPDULength, FirstBurstSize, and MaxBurstSize, all
have Use:LO.
