The external array's performance and status affect the mapped external LU's Read and Write
performance. If there is a heavy load on the external array, the Read and Write operation's
processing speed slows. In this case, I/Os from the mainframe host might have an MIH error.

If the host connected to the local array issues too many I/Os for the external array to process,
commands from the host might time out.
