POST
Power-On Self Test (POST) runs most of the tests that normally occur when the drive is powered ON.
The test checks motors, sensors, memory, and other electronic circuitry in the drive.
Read/Write
Runs a Read/Write test. This test takes approximately 10 minutes for each cycle. A CE scratch tape
must be loaded before you select this test.
Read/Write (Short)
Runs a 4 minute Read/Write test. A CE scratch tape must be loaded before this test is selected.
Note: If the message Use Unlabeled Tape displays, it indicates that the customer tape cartridge
contains data. Do not use this tape cartridge. Instead, use a CE scratch tape to run this test.
Panel
Runs tests on the service panel. Allows the CE to visually check all pixels on the service panel display.
To stop the Panel test, select STOP RUNNING between test cycles.
Test Wrap
Runs test on a drive pair in one row of the 3592 frame. This test ensures that the drive can
communicate to the SDLC cable in the library frame.
Test Frame Wrap (Unplugged From Silo)
This test cannot be run on a Rack Mount drive, since no library is connected.
Compliance
This write-only test runs for 20 minutes. Only available from "CE Engr Use Only menu" on page 145.
Compactor Diag
This test runs internal compactor electronic tests. Only available from "CE Engr Use Only menu" on
page 145.
Test Fibre Wrap
Runs tests on the Fibre Channel by using the wrap plug.
Attention: If the service panel shows the file-protected icon, the tape cartridge is either physically
write-protected or the customer used a command to logically write-protect the tape.
When a test starts to run, the Status menu that is shown in Figure 48 on page 110 displays. The tests run
continuously. To stop a test, select STOP RUNNING, and allow the test to finish the test cycle that is in
process. When a test ends, the results are displayed on Figure 49 on page 110 (the second screen shows
an example of a failure).
Attention: Do not select Force Error Dump from the menu when the tests are running unless you
are sure that the 3592 drive is in a hung condition. Also, when the tests are running, do not change
to operator mode by pressing Change Mode . Aborting a test can cause unexpected results.
The CE DIAGS BLOCKED menu, the third screen in Figure 49 on page 110, can occur if the drive goes
through microcode recovery. To recover from this condition, complete a Reset Drive. See "Services
menu" on page 97.
Test Fibre Wrap menu
Table 70 on page 113 shows the Fibre Wrap menu items. This menu allows the CE to wrap both fibre
ports, or each individually.
Note: Fibre wrap plugs must be attached to the drive or to the end of the cables (with the duplex adapter)
before these tests are run. Running tests without the wrap plug might cause performance or I/O problems
on the fibre loop.
