– If you double-click an SPM group, host bus adapters in that group are
displayed in the tree. the WWN and SPM name are displayed to the
right of the host bus adapter icon ( ).
If the WWN of a host bus adapter (HBA) is displayed in red in the tree, the
host bus adapter is connected to two or more ports, but the traffic between
the HBA and some of the ports is not monitored by Performance Monitor.
When many-to-many connections are established between HBAs and ports,
you should make sure that all the traffic between HBAs and ports is
monitored. For details on the measures when a WWN is displayed in red,
see Monitoring All Traffic between HBAs and Ports.
The list on the right of the tree changes depending on the item you
selected in the tree as follows:
– When you selected the Subsystem folder, the list displays the
information of SPM groups.
– When you selected an SPM group icon ( ), the list displays the
information of host bus adapters ( ) contained in that SPM group.
• The Add WWN button lets you add a host bus adapter to an SPM group. Before using this button, you must select a host bus adapter ( ) from the
upper-left tree and also select an SPM group ( ) from the lower-left tree.
You can add a host bus adapter that appears below Monitor and does not
registered on any other SPM group, yet. If you select a host bus adapter
below Non-Monitor or a host bus adapter already registered on an SPM
group, the Add NNW button is deactivated.
• The list at the upper left corner of the list enables you to change the type
of performance statistics to be displayed in the list.
– If IOPS (I/Os per second) is selected, the list displays I/O rates for
WWNs (host bus adapters). The I/O rate indicates the number of I/Os
per second.
– If MB/s (megabytes per second) is selected, the list displays the
transfer rates for WWNs (host bus adapters). The transfer rate indicates
the size of data transferred in one second.
• The list displays a list of WWNs and indicates the I/O rate or the transfer
rate for each host bus adapter corresponding to the selection in the upper-
left tree or lower-left tree. This list also enables you to specify the host bus
adapter attributes and the upper limit of the host bus adapter traffic.
The measurement unit for the values in the list can be specified by the list
at the upper left corner of the list. The displayed items will change
depending on the selected tree and item. The host bus adapter 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 appear total number of WWNs, the number of
prioritized WWNs, and the number of non-prioritized WWNs.
The list shows the following items:
