NOTE:
• If the graph does not display changes in the transfer rate (for example, if the line in the graph
runs vertically), it is recommended that you change the value in the Chart Y Axis Rate list.
For example, if the largest value in the list is 200 and the value in Chart Y Axis Rate is 100,
you should select a value larger than 200 from Chart Y Axis Rate.
• 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 are
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 the
HP
StorageWorks XP24000/XP20000 Performance Control User Guide.
