Description
Item
A list of WWNs and the I/O rate or transfer rate for each HBA corresponding to the selection
in the upper-left tree or lower-left tree. Use this list to specify the HBA attributes and the upper
limit of the HBA traffic.
The measurement unit for the values in the list can be specified by the choice in the upper-left
corner of the list. The displayed items will change depending on the selected tree and item. The
HBA traffic (I/O rate and transfer rate) is monitored by Performance Monitor. To specify the
monitoring period, use the Monitoring Term area of Performance Monitor.
On the right side of the list is the total number of WWNs, number of prioritized WWNs, and
number of non-prioritized WWNs.
The list contains the following columns (scroll to view all of the columns):
•
WWN: Indicates WWNs of HBAs. This column does not appear when you select the Subsystem
folder in the lower-left tree.
•
Performance Control Name: Performance Control names of HBAs. Use XP Performance Control
to assign a Performance Control name to each HBA so that you can easily identify each HBA
in the Performance Control tabs. This column does not appear when you select the Subsystem
folder in the lower-left tree.
•
Group: The Performance Control group to which the HBA belongs. This column appears when
a port is selected in the upper-left tree and does not appear when a Performance Control
group is selected in the lower-left tree.
•
Per Port: The traffic (I/O rate or transfer rate) between the HBA and the port selected in the
upper-left tree. This item is displayed only when you select an icon in the upper-left tree. The
Per Port column contains the following:
Ave.: Average I/O rate or average transfer rate for the specified period.
Max.: Maximum I/O rate or maximum transfer rate for the specified period.
•
WWN Total: The sum of the traffic (I/O rate or transfer rate) between the HBA and all the
ports connected to the HBA. This value is the total traffic of that HBA. This item is displayed
only when you select an icon in the upper-left tree. Whichever port you select in the tree, the
WWN Total column shows the sum of the traffic to all the ports.
•
The WWN Port column contains the following:
Ave.: Indicates the average I/O rate or average transfer rate for the specified period. The
Ave. column is also displayed when you select an icon in the lower-left tree. In this case, the
Ave. column shows the average value, which is the same as WWN Total. When you select
the Subsystem folder in the lower-left tree, the Ave. column shows the sum of the traffic of the
HBAs registered on each Performance Control group.
Max.: Indicates the maximum I/O rate or maximum transfer rate for the specified period. The
Max. column is also displayed when you select an icon in the lower-left tree. In this case, the
Max. column shows the maximum value, which is the same as WWN Total. When you select
the Subsystem folder in the lower-left tree, the Max. column shows the sum of the traffic of
the HBAs registered on each Performance Control group.
•
Attribute: The priority of each WWN. Prio. indicates a prioritized WWN. Non-Prio. indicates
a non-prioritized WWN. For details on how to change the priority, see “
If one HBA connects to multiple ports, the attribute setting of the HBA is common to all the
ports. Therefore, if you specify an HBA as a prioritized WWN or a non-prioritized WWN
for one port, that setting is applied to all the other connected ports automatically.
