Abstract: This document is a collection of instructions for generating the appropriate Performance Tools reports needed as input to Disk Magic. Download the document that best meets your needs.
If your system is not running IBM i 7.1 or higher, please refer to the directions in the PDFs below.
IBM i Performance Data Investigator (PDI) can export IBM i performance data to .csv files that can be processed by Disk Magic automatically.
How to generate a .csv file in PDI:
Sign on to IBM Navigator for i by using the URL https://yoursystemname:2001 replacing 'yoursystemname' with the name your IBM i is known by on your network.
In the left hand navigation tree, select Performance -> Investigate Data -> Collection Services -> Disk > Disk Reads and Writes Detail.
Use the pull downs to select the collection library and collection name you wish to use for import to disk magic and click "Display"
Export the first view, "Performance Data Investigator IBM i Model DSS".
Ensure format is set to "Comma Delimited (*.csv). And select "All data" for the data range before clicking "OK"
Depending on your browser settings, a file will be placed in your downloads folder or you will be prompted to save the file. Locate this file and send along to the person performing your disk magic study.
