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

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

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
