Interpreting POST results POST is a system check that is performed each time the switch is powered on, rebooted, or reset. During POST, the LEDs flash different colors. Any errors that occur during POST display in the error log. To determine that POST completed successfully and whether or not any errors were detected: 1. Verify that the switch LEDs indicate that all components are healthy. If one or more LEDs do not display a healthy state, verify that the LEDs on the switch are not set to "beacon" using the switchshow command. 2. Verify the switch prompt displays on the terminal of a computer workstation connected to the switch. If there is no switch prompt when POST completes, press Enter. If the switch prompt still does not display, try opening another telnet session or accessing through another management tool. If this is not successful, the switch did not successfully complete POST; contact your HP Technical Support. 3. Review the switch system log for errors. Any errors detected during POST are written to the system log, accessible through the errshow command. For information about all referenced commands, and on accessing the error log, refer to the HP StorageWorks procedures user guide and the HP StorageWorks diagnostics and system error messages reference guide for the Fabric OS version running on your switch. All supporting Fabric OS documentation resides on the Software CD that shipped with your switch. Diagnostic tests In addition to POST, Fabric OS includes diagnostic tests to help troubleshoot the hardware and the firmware. This includes tests of internal connections and circuitry, fixed media, and the transceivers and 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, transceiver, and cable. All diagnostic tests are run at link speeds of both 1 Gb/sec and 2 Gb/sec. CAUTION: Diagnostic tests can temporarily lock the transmit and receive speed of the links during diagnostic testing.

SAN Switch 2/8V, 2/16V, 2/16N and 4/32 installation guide

Interpreting POST results

POST is a system check that is performed each time the switch is powered on, rebooted, or

reset. During POST, the LEDs flash different colors. Any errors that occur during POST display in

the error log.

To determine that POST completed successfully and whether or not any errors were detected:

Verify that the switch LEDs indicate that all components are healthy. If one or more LEDs do

not display a healthy state, verify that the LEDs on the switch are not set to “beacon” using

the

switchshow

command.

Verify the switch prompt displays on the terminal of a computer workstation connected to

the switch. If there is no switch prompt when POST completes, press

Enter

. If the switch

prompt still does not display, try opening another telnet session or accessing through

another management tool. If this is not successful, the switch did not successfully complete

POST; contact your HP Technical Support.

Review the switch system log for errors. Any errors detected during POST are written to the

system log, accessible through the

errshow

command.

For information about all referenced commands, and on accessing the error log, refer to the

StorageWorks procedures user guide

and the

HP StorageWorks diagnostics and system error

messages reference guide

for the Fabric OS version running on your switch.

All supporting Fabric OS documentation resides on the Software CD that shipped with your

switch.

Diagnostic tests

In addition to POST, Fabric OS includes diagnostic tests to help troubleshoot the hardware and

the firmware. This includes tests of internal connections and circuitry, fixed media, and the

transceivers and 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, transceiver,

and cable.

All diagnostic tests are run at link speeds of both 1 Gb/sec and 2 Gb/sec.

CAUTION:

Diagnostic tests can temporarily lock the transmit and receive speed of the links

during diagnostic testing.
