Measuring traffic between host bus adapters and ports for many-to-many connections
If a many-to-many connection is established between host bus adapters (HBAs) and ports, you must
measure traffic between each HBA and the port to which the HBA is connected.

Add WWN dialog box
7.
Specify the WWN and PFC name (16-character maximum), and click OK. The specified WWN
appears below Monitor.
NOTE:
To simplify managing HBAs, use the same name for the PFC name and HBA nickname.
NOTE:
Performance Control XP does not monitor HBAs below Non-Monitor. You cannot set upper
limits and thresholds to HBAs that are not monitored. To move an HBA (WWN) from Monitor to
Non-Monitor, select an HBA from below Monitor, right-click Monitor, and select Delete WWN. You
can monitor up to 32 HBAs (WWNs) for each port.
