Problem summary

  • Client appears stuck waiting for commands to complete, the
    command is successfully returned to client once client cancels
    the command.
    

Problem conclusion

  • Code that remembers I/O requests that failed to allocate
    resources was encapsulated and improved so that driver is able
    to send such commands once resources are available without
    starving and individual SCSI target of NPIV clients.
    

Temporary fix
