Example 2:
The following shows an example of information acquired by executing sample script KTDEMO13 (the
KTLOAD , KTQRYTPG , and KTQRYRLC commands). This information shows the page relocation status
of each volume in the tiering policy group TPG1 and the tier relocation progress for each Smart Tiers
Z pool.

Checking volume I/O performance
By executing the KTQSTATS command, you can acquire I/O performance information (number of
I/O operations for the drive media) for each volume in a tiering policy group. You can view the
acquired information to check if there is any problem with the I/O performance of volumes.
Prerequisites
• Creating a tiering policy group definition file
To check volume I/O performance:
1. Execute the KTLOAD command.
The contents of the configuration files are loaded into REXX variable structures.
