Gabriel,

We are working diligently with T10 to have exceptions like task-set-full,
busy etc. cause an ACA or ACA-like condition and thus help maintain order.

Subject:  iSCSI command numbering




hi

when an iSCSI target recives task with CmdSN=X and decides to reject it
because of internal queueing issues( e.g. queue is full...)
what should the  target do when it sees the next task with CmdSN=X+1 ?
    a) accept it ( it saw CmdSN=X  so there are no flows in the network
layer ) OR
    b) buffer it, waiting for task with CmdSN=X  to be resent( ensure total
ordering on the tasks )
