Diagnostic Tests
Read the following sections for information on using POST and diagnostic tests.
Interpreting POST Results
Each time the switch is powered on or reset, the switch automatically performs
POST, a one minute system check during which the port status LEDs flash
different colors.
To determine whether POST completed without errors, verify that all LEDs return
to a normal state after POST is complete. If one or more LEDs do not return to a
normal state, and this is not due to the switch being set to beacon, refer to the HP
StorageWorks Fabric OS Procedures Version 3.1.x/4.1.x User Guide.
Note:
If the switch prompt does not display when POST completes, POST was not
successfully completed and the switch should be returned to your switch supplier for
repair.
Any errors detected during POST are written to the system log, accessible through
the
errShow
command. For more information about error messages, refer to the
HP StorageWorks Fabric OS Procedures Version 3.1.x/4.1.x User Guide.
Diagnostic Tests
Diagnostic tests are provided to help troubleshoot the hardware and the firmware.
The diagnostic tests provided on the switch include tests of internal connections
and circuitry, fixed media, and any SFP modules and fiber optic cables in use. The
tests are implemented by command, either through a telnet session or through a
terminal set up for a Serial connection to the switch. Some tests require the ports
to be connected by external cables, to allow diagnostics to verify the
serializer/deserializer interface, as well as the attached SFP and cable.
All diagnostic tests are run at link speeds of both 1 Gbps and 2 Gbps. For
information about the specific diagnostic tests and how to run them, refer to the
HP StorageWorks Fabric OS Procedures Version 3.1.x/4.1.x User Guide.
Note:
The transmit and receive speed of the links may be temporarily locked to a
specific speed during diagnostic testing.
