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.
Testing the Read and Write Capabilities of a Disk Drive
Run a DILX Basic Function test to test the read and write capability of
a disk drive. During the Basic Function test, DILX runs the following
four tests. (DILX repeats the last three tests until the time that you
specify in step 6 on page 4–40 expires.)
n Write test. Writes specific patterns of data to the disk drive (see
Table 4–15 on page 4–39.) DILX does not repeat this test.
n Random I/O test. Simulates typical I/O activity by issuing read,
write, access, and erase commands to randomly-chosen logical
block numbers (LBNs). You can set the ratio of these commands as
well as the percentage of read and write data that are compared
throughout this test. This test takes six minutes.
n Data-transfer test. Tests throughput by starting at an LBN and
transferring data to the next LBN that has not been written to. This
test takes two minutes.
n Seek test. Stimulates head motion on the disk drive by issuing
single-sector erase and access commands. Each I/O uses a different
track on each subsequent transfer. You can set the ratio of access
and erase commands. This test takes two minutes.
