    The Storage Path chart displays historical statistics for paths used by the storage adapter on the selected host.

    Storage Path Performance Chart

    You can switch between adapters using the Adapter list below the performance chart.

    The name of each storage device connected to the storage adapter through the selected path is specified after the host address (separated by a forward slash). It has the following format: <HBA>:<SCSI target>:<SCSI LUN>:<disk partition>

    The following table provides information on predefined views and counters.
