For example, the following representative screen display shows information about data rates
associated with the highlighted EVA array host port.

EVA Array Discovery
The following paragraphs describe important considerations in the EVA array discovery process to
support the EVA Array Performance Pack.
Discovery Considerations Using Command View EVA
If you performed EVA array discovery previously using the SMI-S provider (as with earlier Command
View EVA versions), Array Performance Pack requires discovery (or rediscovery) of EVA Arrays using
the supported Command View EVA version, which utilizes the built-in provider. (By default,
Management Server Build 6.x discovers EVAs using the built-in provider.)
You should have run Discovery Data Collection on an EVA before the Performance Monitoring tree
will be populated with the corresponding EVA Elements used for corresponding metric selection.
Any configuration changes to the EVA array (i.e., addition or deletion of mapped volumes) requires
a Discovery Data Collection in order for the changes to be reflected in the Performance Monitoring
tree, and in the actual performance data collected. Also, changes in the number of elements (i.e.,
disks or volumes) can impact the aggregated performance metric data.
If you make changes to your selection of EVA arrays later, you must ensure the selected new EVA
arrays have been discovered using the required Command View EVA version. For more information
regarding discovery procedures, refer to the management server installation guide.
