Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
Use the following steps to test the read and write capabilities of a specific disk drive:
1. From a host console, dismount the logical unit that contains the disk drive you
want to test.
2. Connect a terminal to the maintenance port of the controller that accesses the
disk drive you want to test.
3. Run DILX with the following command:
RUN DILX
4. Decline the auto-configure option so that you can specify the disk drive to test.
IMPORTANT: Use the auto-configure option if you want to test the read and
write capabilities of every disk drive in the subsystem.
5. Decline the default settings.
6. Enter the number of minutes you want the DILX Basic Function test to run.
NOTE: To ensure that DILX accesses the entire disk space, you should enter 120 or
more.
7. Enter the number of minutes between the display of performance summaries.
8. Choose to include performance statistics in the summary.
9. Choose to display both hard and soft errors.
