While implementing a second SAN director in their environment, a customer moved several hosts
and one of their two storage arrays onto the new director. When a large batch cycle was run, the
customer experienced queuing on the directors when previously there was none. However, when
the batch process was rerun with all LUNs made available through the original director, no
problems were encountered.
