“After Primary Changes” Sections
When GPA analyzes a system, it considers whether making changes in the location of
the primary disk process for each logical volume will help the overall performance of
the system. If GPA determines that the performance of the system will be improved,
and that there are sufficient resources available on the CPU with the backup disk
process, GPA recommends changing the primary disk process to the location of the
backup. When it does this, GPA produces three new sections in its standard report that
show the predicted performance of the system after the primary changes. Each of
these sections has the words “After Primary Changes” included in its title so that they
can be easily identified.
GPA determined that primary disk process changes would help the performance of
\NODEB. Examples 4-19 through 4-23 are examples of these sections.
