Diagnose Controller Iscsi Host Cable - IBM System Storage DS3000 Programming Manual

Notes
When you run a data loop-back test, you can optionally specify a file that contains a data pattern. If you
do not specify a file, the controller firmware provides a default pattern.
Discrete lines are control lines and status lines that are connected between two controllers in a controller
module. The discrete lines diagnostic test lets each controller check that control signal migrations can be
observed at the control inputs of the alternate controller. The discrete lines diagnostic test automatically
runs after each power-cycle or each controller-reset. You can run the discrete lines diagnostic test after
you have replaced a component that failed the initial discrete lines diagnostic test. This test applies only
to the DS5100, DS5300, and DS4800 (models 82, 84, and 88) series controller modules. The discrete lines
diagnostic test returns one of the following messages:
v When the discrete lines diagnostic test runs successfully, this message appears:
The controller discrete lines successfully passed the diagnostic
test. No failures were detected.
v If the discrete lines diagnostic test fails, this message appears:
One or more controller discrete lines failed the diagnostic test.
v If the CLI cannot run the discrete lines diagnostic test, the CLI returns Error 270, which means that the
discrete lines diagnostic test could not start nor complete.
v The discrete lines diagnostic test is not functioning in SM release version 10.60.x5.11. Check the SM
release readme files for information.

Diagnose Controller iSCSI Host Cable

This command runs diagnostic tests on the copper cables between iSCSI Host interface cards and a
controller. 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 [(a | b)]
iscsiHostPorts=(all | ("wwID" | "gID")
testID=cableDiagnostics
Parameters
Parameter
controller
iscsiHostPorts
testID
Notes
When you run the cable diagnostic test, the firmware returns the following information:
v Host Port: The port on which the diagnostic test was run.
v HIC: The host interface card associated with this port.

Description
The controller on which you want to run the cable
diagnostic test. Valid controller identifiers are a or b, where a
is the controller in slot A, and b is the controller in slot B.
Enclose the controller identifier in square brackets ([ ]). If
you do not specify a controller, the storage management
software returns a syntax error.
The 8-byte World Wide Identifier (WWID) or the 16-byte
group identifier (GID) of the HBA or HCA host port. Enclose
the WWID or the GID in double quotation marks (" ").
The identifier for the diagnostic test that you want to run.
For this diagnostic test, the only choice is cableDiagnostics.
