After entering values for the above prompts, connect the SCSI ports with the wrap cable. Be
sure to use the correct SCSI cable type for the type of SCSI port. When the SCSI wrap cable is
securely attached to both ports, press the Enter key as indicated in the Diagnostics menu to
begin the test.
For iterative tests, the results “PASSED” or “FAILED” will be displayed upon completion of
the test. For tests set to run forever, results will be displayed only in the event of a failure. If a
failure does occur, the address of the failure will be displayed. Otherwise, disconnect the SCSI
wrap cable to end a forever test. This should result in a failure message (since the cable is now
disconnected) and the test will end. If no failure message appears when the SCSI wrap cable is
disconnected during the wrap test, then there likely is a problem. Refer to the Troubleshooting
Section of this manual for additional assistance.
• Select 3 to perform a loopback test of the Fibre Channel connection on the back of the
VT5900-SA unit. For the test to be performed correctly, a Fibre Channel loopback connector
must be attached to the VT5900-SA’s Fibre Channel port before selecting this option.
Selecting X (exit) from System Diagnostics Mode has a confirmation message to verify the
selection. If Y (yes) is given to the confirmation message, the VT5900-SA will restart itself and
enter normal operation mode. The power up messages appear followed by the main menu.
SCSI Command Tracking
When this option is selected from the System Utilities menu, the SCSI Command Tracking Menu
is displayed.

• Select 1 to toggle SCSI Command Tracking ON or OFF. When toggled ON, all SCSI
commands received or transmitted to or from the VT5900-SA are logged. When OFF, these
commands are not logged. When set to ON, menu options 2 through 4 are also available from
this menu.
Note: When exiting System Diagnostics Mode, remove any diagnostics cables
before restarting the unit.
