Ports and HBAs connected to those ports in the storage system. Ports on the storage system are
shown below the Subsystem folder. The ports are indicated by icons such as
and
.
When you double-click a port, the tree expands to display two items: Monitor and Non-Monitor.
The HBAs that are connected to the specified port are displayed below Monitor or Non-Monitor.
•
If you double-click Monitor, the HBAs (
) whose traffic with the specified port are monitored
is displayed below Monitor.
•
If you double-click Non-Monitor, the HBAs whose traffic with the specified port is not monitored
are displayed below Non-Monitor.
The WWN and Performance Control names of the HBAs are displayed to the right of the HBA
icon (
) below Monitor. WWNs (WorldWide Name) are 16-digit hexadecimal numbers used
to uniquely identify HBAs. Performance Control names are nicknames assigned by the system
administrator so that they can easily identify each HBA.
Only the WWN is displayed to the right of the HBA icon (
) below Non-Monitor.
When many-to-many connections are established between HBAs and ports, make sure that all
the traffic between HBAs and ports is monitored. Therefore, make sure that all the connected
HBAs are displayed under Monitor. For details on how to move an HBA displayed below
Non-Monitor to below Monitor, see “
Monitoring All Traffic between HBAs and Ports
The list to the right of the tree changes depending on the item you select in the tree:
•
When you select a port or Monitor icon, the list displays the information for HBAs that are
connected to the ports and monitored by Performance Monitor.
•
When you select the Monitor icon or the Subsystem folder, the list is blank.
