2.3.1 Running the System Exerciser
The system exerciser performs a more thorough test of the RX23 disk and
the SCSI adapter module. It performs a read/write operation during the
second pass of the exerciser when the special-keyed test diskette is loaded
in the RX23 drive before starting the system exerciser. To run the system
exerciser:
1. Install a loopback on the communication port.
2. Load the special-keyed test diskette in the RX23 drive. If the diskette
does not contain the special key, go to Section 3.2 and perform the
procedure to write the special key on the diskette.
3. Enter TEST 80000106
Return
.
? >>> 7
Return
.
4. Read the results on the screen during the test.
5. Press the Halt button to stop the exerciser.
System Exerciser Results
A code of 5300.0001 listed under the SCSI-A bus indicates that there are
no errors for the RX23 and that the read/write operation is successful.
A code of 5100.0001 listed under the SCSI-A bus indicates that there are
no errors. However, a no write operation took place either because the
exerciser is still executing the first pass, or the special key is not found on
the diskette, or no diskette is loaded.
