diagBoot
.
•
It erases the new persistent device map and renames the original map file

Diagnostic Commands
This section is a reference for the commands that are available when the SNC 4000 is booted in diagmode.
The command set is limited while in
diagmode
. You will need to use the
showBox
command and three
commands (with the suffix
Test
) when testing the Ethernet, FC, and SCSI interfaces.
The Ethernet loop back plug, FC loop back plug, and SCSI cable provided in the Service Tool Kit are
required for the corresponding loop back test.
elTest
elTest
is the Ethernet loop back test. The SNC 4000 must be in diagnostic mode to use this command
and a loop back plug must be installed on the Ethernet port.
diagmode > elTest
==== Testing Ethernet ====
Init complete.
Ethernet OK
value = 0 = 0x0
The test issues a series of loop back tests. Test data is transferred and verified. A good test ends with
Ethernet OK.
If errors are detected, the test displays the number of bad test iterations as shown below. If your test was
not succesful, return to the MAP that sent you here.
diagmode > elTest
==== Testing Ethernet ====
Init complete.
Ethernet timeout error
Ethernet timeout error
Ethernet timeout error
Ethernet timeout error
Ethernet timeout error
Ethernet timeout error
Ethernet test reported 6 errors out of 12 iterations
value = 6 = 0x6
fcSlotTest [x]
The SNC 4000 must be in diagnostic mode to use this command and a loop back plug must be connected
to the SFP.
CAUTION
You must disconnect the FC and SCSI cables from the SNC 4000. If
you do not, the data on the attached disk or tape devices will become
corrupted.
