Diagnostics Mode
When this option is selected from the System Utilities menu, a confirmation message will appear
to verify the selection. If a response of Y (yes) is given to the confirmation message, current
VT5900-SA activities will be interrupted while the unit restarts itself and enters diagnostics mode.
The power up messages will appear followed by the diagnostics menu.

Select 1 to perform a loopback test of the Ethernet connection on the back of the VT5900-SA
unit. For the test to be performed correctly, an Ethernet loopback connector must be attached
to the VT5900-SAs Ethernet port before selecting this option.
Select 2 to perform a wrap test of the SCSI ports on the back of the VT5900-SA unit. The
SCSI wrap test is performed a little differently depending on the model of VT5900-SA being
tested.
When Perform SCSI External wrap Test is selected, the following prompts appear:
Number of Test Iterations (1-10000) or Forever (F):
Entering F or an integer in the range of 1 to 10,000 sets the number of times the test will
repeat—the smaller the number, the quicker the test will reach completion.
Initiator SCSI Port # (0-1):
Enter the port number for the port that will serve as the Initiator during the wrap test.
Target SCSI Port # (0-1):
Enter the port number for the port that will serve as the Target during the wrap test. The port
number designated here should not be the same port number as designated for the Initiator
SCSI Port.
For the SCSI wrap test, it does not matter which port is designated the Initiator and which is
designated the Target. Both ports will be tested.

3) Perform Fibre Channel Loopback Test
X) Exit diagnostics mode and reboot
Note: Forever (F) tests in a continuous loop until either the test fails or the
VT5900-SA is powered off and on again.
