IBM SY44-5902-05 manual Verify optical storage unit, Verify diskette, Verify tape

2.You can test some workstations by using the Test Request function key while the operating system Sign On display is shown.

3.See the specific device information for possible off-line tests that you can run.

Verify optical storage unit

You can check optical storage units for correct operation by performing the verification procedure (see “Hardware Service Manager — Verify” on page 95).

Optical storage unit test descriptions

When you select the Verify option (see “Verification procedures” on page 95) on an optical resource that supports a verification function, the test performs the following:

vWrites to the test media if writeable (and supported).

vReads the test media

vVerifies that the interface between the system and the optical storage unit is valid

Verify diskette

You can check diskette subsystems for correct operation by performing the verification procedure.

Diskette test descriptions

When you select the Verify option (see “Verification procedures” on page 95) on a diskette resource that supports a verification function, the test performs the following:

vRuns the diskette controller hardware test

vReads a diskette to verify that the system data area is valid

vRuns simple operations to verify that the diskette unit is operating correctly

The test does not:

vVerify write operations for the diskette unit

vCalculate the number of read errors for a specific diskette

If the test fails, an entry might be created in the product activity log. Use the information in the product activity log to assist in problem analysis (see Chapter 3, “Product Activity Log” on page 99).

Verify tape

You can check tape subsystems for correct operation by performing the verification procedure.

Tape test descriptions

When you select the Verify option on a tape resource that supports a verification function (for example, type 6380), the test performs the following:

vRuns a read, write, or erase function on the tape.

vTests the interface between the system and the tape unit.

vRuns simple operations to verify that the tape unit is operating correctly.

If the test fails, the system will display a message that describes the failure. An entry might also be created in the product activity log. Use the message or the information in the product activity log to assist in problem analysis (see Chapter 3, “Product Activity Log” on page 99).
