Notes for Test Device, Test Drive, Test Media, and Test Head:
• If the message Use Unlabeled Tape displays, it indicates that a customer tape cartridge was loaded. Do not use this customer tape cartridge because it might contain customer data. Instead, use a CE scratch tape to run this test.
• If the message Wrong Tape Type - Cannot use WORM displays, it indicates that a WORM tape was loaded. You cannot use this tape cartridge type. Instead, use a CE scratch tape to run this test.
Test Device
Runs most of the tests that normally occur when the drive is powered ON (POST). Also, the CE is requested to load a CE scratch tape to run the calibrate drive, read/write, and tape motion tests.
These tests calibrate the read/write channel to optimum settings, run the long read/write test with all servo positions, and exercise all of the tape motion functions of the drive. This test takes
approximately 18 minutes to run.
Test Drive
This test is a shortened version of the Test Device diagnostic test. It does not include the POST diagnostic test, calibrate drive test, or unique tape motion test. It checks the motors and head, by running write and read tests on a shortened section of tape, both inbound and outbound. This test takes approximately 4 minutes to run.
Note: Certain errors that are detected while this diagnostic test run automatically starts a drive calibration. This procedure is followed by a rerun of the short write and read test. For these errors, the diagnostic run time is increased from 4 to 9 minutes.
Test Media
Run this test when requested by the customer. This test overwrites any customer data on a data tape cartridge. Runs Read/Write tests on the outer tracks of the tape to verify the media tracking and performance. This test takes approximately 9 minutes to run.
Test Head
Runs Read/Write tests on the inner tracks of the tape to verify the head performance. This test takes approximately 6 minutes to run.
Test Panel
This test always fails on a Rack Mount drive, since a physical service panel cannot be connected.
Test Wrap
Runs test on a drive pair in one row of the 3592 frame.
Test Frame Wrap
This test cannot be run on a Rack Mount drive, since no library is connected.
Test Fibre Wrap
Runs tests on the Fibre Channel through the Fibre Channel wrap plug.
Loop Diag
Allows the CE to loop the diagnostic tests from “CE Loop Diag menu” on page 111.
Status menus
When a single-pass diagnostic test starts to run, the Status menu displays.

Force Error Dump
-When the drive is writing data on the tape, the Tape Position Indicator (see Figure 33 on page 79) displays a graphical representation of the position of the device relative to the tape.
The dump icon displays when the dump is available, and remains on the screen to indicate that trace data is stored in the drive. The icon is not displayed after the host requests a dump or the dump is written to tape. While the dump is transferred, there is no indication of progress until the dump icon reappears in the lower right of the service panel. See “Dump icons” on page 83 for information about the flash dump icon.
Attention: Trace data in a new dump is volatile and is lost if you press Reset or you remove power from the device.
The flash dump icon displays when a dump is available in flash memory. This dump is preserved over power cycles.
Cancel
Causes the CE Options menu to display.
Force Dump
Causes a dump to control-store DRAM to occur. The initiator can retrieve the data with a Read Buffer command to the control store DRAM.
Attention: Do not use this option if an FID1 condition already caused a dump to be created.
For this case, the dump data of interest is lost if you run the Force Dump function. The dump that is caused by using this option writes over an existing dump. Do not use Force Dump if the bus is in a hung state; instead, use Force Error Dump.
Copy Dump to Tape
Copies the dump data to a cartridge. A menu prompts the CE to load a scratch tape.
Attention: Data on the tape can be overwritten. The CE Actions menus (Figure 50 on page 111 and Figure 51 on page 111) indicate the status of the copy to tape (either, successful copy or unsuccessful copy).
Copy Dump to Flash
Copies dump data to flash memory. The flash dump icon displays when a dump is available in flash memory. Saving the dump to flash memory preserves the dump over power cycles. FID ED is reported after POST when a dump is saved in flash memory (also see “Offloading the dump to flash memory”
on page 211).
Clear Flash Dump
Allows CE to clear the flash dump memory and the auto dump flash memory (also see “Clearing flash dump memory” on page 211).
Force Error Dump
Causes a recovery procedure in which the microcode is reloaded. This option is used if a microcode-hang condition exists (that is, the host cannot communicate with the drive and no hardware fault is detected). When a hang condition exists, the host can attempt to request a microcode dump through a port, but does not receive it from the drive. This option is also used if a microcode dump is needed and the Force Dump option on this menu cannot provide a dump. The host is then able to successfully request the dump information with the port, or the CE can use the Copy Dump to Tape option on this menu.
Attention: Using this option causes an existing dump to be overwritten.

Microcode Update…
Allows the CE to replace the microcode in the device from a field microcode replacement (FMR) tape (cartridge) and to update the FMR tape with the microcode. A menu prompts the CE to load the FMR tape into the device. When the 3592 drive reads the FMR tape, it checks the EC level on the tape cartridge. If the tape does not contain the EC level of the drive, it automatically writes the microcode to the FMR tape. It then displays the EC level with the “CE Select Level menu” on page 116.
Make FMR Tape…
Allows the CE to create a field microcode replacement (FMR) tape (cartridge) from a scratch tape. The FMR tape contains the current level of microcode that is active in the device. A menu prompts the CE to load a scratch tape in the device. After the tape is written, the final status menu indicates whether the operation was successful.
Note: You cannot use this FMR tape to run diagnostic tests until you unmake the FMR tape.
Unmake FMR Tape…
Allows the CE to convert an FMR tape (cartridge) to a scratch tape. A menu prompts the CE to load an FMR tape in the device. After the tape changes the header information, the final status menu indicates whether the operation was successful.
Attention: If the service panel shows the write-protected icon. The tape cartridge is either physically write-protected or the customer used a command to logically write-protect the tape.

CE Select Level menu
Table 75 on page 116 shows the CE Select menu items. This menu displays when the device loads an FMR tape (cartridge). The device reads all the EC levels, and displays them on this menu. The invalid EC levels are displayed in a lighter font. The message lines display the EC level that runs in the device. The ECs are displayed in the same order as they appear on tape. The CE chooses which EC level to load into the device.
To activate the drive microcode after you load it, you must complete a power-on reset or a CE reset.
Operational Note: If you insert the FMR cartridge, and the EC level of the microcode is not on the cartridge, the microcode is copied automatically from the drive to the cartridge.
