CLI Guide

This command runs diagnostic tests on the copper cables between the iSCSI Host interface cards and a
RAID controller module. You can run diagnostics on a selected port or all ports. The ports must be able
to support the cable diagnostics. If the ports do not support cable diagnostics an error is returned
Syntax
diagnose controller [(0 | 1)]
iscsiHostPort[(all | (0 | 1))]
testID=cableDiagnostics
Parameters
Parameter Description
controller
Controller specifies the RAID controller module on
which you want to run the cable diagnostic test.
Valid RAID controller module identifier values are 0
and 1. The identifier value is 0 for the RAID
controller module on the top and
1 for the RAID
controller module on the bottom when viewed
from the rear of the enclosure. Enclose the RAID
controller module identifier in square brackets ([ ]).
If a RAID controller module is not specified, the MD
storage management software returns a syntax
error.
iscsiHostPort
Specifies the iSCSI host port on which you want to
run the diagnostic tests. You can either run the
diagnostics on all iSCSI host ports or run it on a
specific iSCSI host. Valid values for the specific
iSCSI host port identifiers are 0 or 1. Enclose the
iSCSI host port identifier in square brackets ([ ]).
testID
Specifies the identifier for the diagnostic test you
want to run. For this diagnostic test, the value is
cableDiagnostics.
Notes
When you run the cable diagnostic test, the firmware returns the following information:
• Port: The port on which the diagnostic test was run.
• The date and time the test was run.
• RAID Controller Module
• Status:
– OK: All of the pairs of cables are good and do not have any faults.
– Open: One or more of the four pairs of cables are open.
– Short: One or more of the four pairs of cables are shorted.
• Incomplete: One or more of the four pairs returned incomplete or invalid test results.
• Cable Length: The length of the cables are listed in meters and the following information about the
