Before using Performance Control, you must find the WWN (Worldwide Name) of each host bus
adapter in host servers. WWNs are 16-digit hexadecimal numbers used to identify host bus
adapters. For details on how to find WWNs, see the XP7 Provisioning for Open Systems User
Guide.
When using Performance Control, ensure that all host bus adapters connected to ports in the
storage system are monitored. Use the WWN tab of the Performance Control main window to
monitor host bus adapters. Place host bus adapters connected to each port below the Monitor
icons.
In Network B, each of the four ports in the storage system is connected to three host bus adapters
(wwn01, wwn02, and wwn03). Place the host bus adapter icons of wwn01, wwn02, and wwn03
below the Monitor icons for all four port icons.
Performance Control is not able to monitor and control the performance of hosts whose host bus
adapters are placed below the Non-Monitor icon. Therefore, make sure to place host bus adapters
below the Monitor icons.
