Decide Whether to Manage the Data Paths
If each of your HBAs is using less than half of its capacity or if your HBAs bear
about the same amount of traffic, it is best to continue using the default settings.
However, in some situations, you could improve performance by changing the
path settings. For example, there may be a high level of traffic on a particular LUN
because it contains a database. From the Performance Monitor, you can see that a
particular HBA has a high volume of traffic. Manage paths to make sure that this
LUN has all optimal paths configured.
