1. In the device listing (the By Product or By Connection tab), select the library or drive to test.

3. Select the tape drives for the Drive Performance test. All of the drives will be tested in parallel.
NOTE: You cannot select the library because the test only runs on tape drives.
4. Click the Options button to configure the test data in the Drive Performance Test dialog. To
return all of the options to their default values, click Defaults.
In the Test Logic section of the dialog, use the drop down menus to select a data type for each
of the four tests. The Drive Performance test is actually a series of four write/read subtests
(labeled Step 1-4 on the Drive Performance screen) that measure performance using different
types of data that you can specify.
The following data types can be selected:
•
Zeros
•
1.6:1 Compression
•
2:1 Compression (suggested starting value)
•
3:1 Compression
•
4:1 Compression
You must specify a data type for Step 1, but you can choose not to perform Steps 2 through
4 by selecting No Test (suggested starting value for steps 2 through 4 is No Test).
