Testing the Read Capability of a Disk Drive
Use the following steps to test the read capability of a 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 maintenace 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.
5. Accept the default test settings and run the test in read-only mode.
6. Enter the unit number of the disk drive you want to test. For example, to test
D107, enter the number 107.
7. If you want to test more than one disk drive, enter the appropriate unit numbers
when prompted. Otherwise, enter “n” to start the test. Use the control sequences
listed in Table 4–14 to control DILX during the test.
