connected to ports on the storage system.

If XP Performance Control is enabled, Performance Monitor provides statistics about traffic between
HBAs and storage system ports. The traffic statistics reveals the number of I/O requests that have
been made from hosts and also reveals the size of data transferred between hosts and storage system
ports. For details on how to view traffic statistics about HBAs, see

Overview of Export Tool

Use the Export Tool to export monitoring data (that is, statistics) shown in the Auto LUN window to
