Description
Item
The WWN and PFC names of the host bus adapters are displayed on the right of the host bus
adapter icon (
) below Monitor. WWNs (Worldwide Name) are 16-digit hexadecimal
numbers used to uniquely identify host bus adapters. PFC names are nicknames assigned by
the system administrator so that they can easily identify each host bus adapter.
Only the WWN is displayed on the right of the host bus adapter icon (
) below Non-Monitor.
When many-to-many connections are established between host bus adapters (HBAs) and ports,
make sure that all traffic between HBAs and ports is monitored. Therefore, make sure that all
connected HBAs are displayed below Monitor. For details on how to move an HBA displayed
below Non-Monitor to below Monitor, see
“Monitoring all port-HBA traffic: many-to-many
.
The list on the right of the tree changes depending on the item you select in the tree as follows.
•
When you select a port or Monitor icon, the list shows the information of host bus adapters
that are connected to the ports and monitored by Performance Monitor.
•
When you select the Monitor icon or the Storage System folder, the list becomes blank.
PFC groups and host bus adapters (WWNs) in each PFC group:
Lower-left tree
•
PFC groups (
), which contain one or more WWNs, appear below the Storage System
folder. For details on PFC groups, see
“Working with PFC groups” (page 66)
.
•
If you double-click a PFC group, host bus adapters in that group expand in the tree. The
WWN and PFC name appear to the right of the host bus adapter icon (
).
If the WWN of a host bus adapter (HBA) appears 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, make sure that all traffic between HBAs and ports is monitored. For details on
the measures when a WWN is displayed in red, see
“Monitoring all port-HBA traffic:
many-to-many connections” (page 59)
The list on the right of the tree changes depending on the item you selected in the tree as follows:
•
When you select the Storage System folder, the WWN list shows the information of PFC
groups.
•
When you select a PFC group icon (
), the WWN list shows the information of host bus
adapters (
) contained in that PFC group.
Adds a host bus adapter to a PFC group. Before using this button, you must select a host bus
adapter (
) from the upper-left tree and also select a PFC group (
) from the lower-left tree.
Add WWN
You can add a host bus adapter that appears below Monitor and is not yet registered on any
other PFC group. If you select a host bus adapter below Non-Monitor or a host bus adapter
already registered on a PFC group, the Add NNW button is unavailable.
Allows you to change the type of performance statistics to be displayed in the WWN list.
Statistic type
•
If IOPS (I/Os per second) is selected, the list displays I/O rates for ports. 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 ports. The
transfer rate indicates the size of data transferred via a port in one second.
A list of WWNs and 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. Use this list to specify the host bus adapter
attributes and the upper limit of the host bus adapter traffic.
WWN list
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.
