“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.
