Power On Self-Test; Checking Post Results - HP StorageWorks SAN Switch 2/32 Installation Manual

Installing the SAN Switch 2/32

Power On Self-Test

Each time the switch is powered on, rebooted, or reset, the switch automatically runs
POST. During POST, the port status LEDs flash, verifying that the switch is operating
properly. POST completes in approximately six minutes, with total boot time
approximately seven minutes.
POST runs through the following test cycles:
• Preliminary POST diagnostics
• Initialization of operating system
• Initialization of hardware
• Diagnostic tests are run on a number of functions, including circuitry, port
functionality, memory, parity, statistics counters, and serialization
For example, if the switch prompt does not display when POST completes, POST was
unsuccessful. Contact your authorized HP switch supplier for more information.
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), see "Interpreting LED
Activity," in Chapter 3.
NOTE: For more information about beaconing, refer to the hp StorageWorks Fabric OS
Procedures Version 3.0.x/4.0.x User Guide

Checking POST Results

Check the success/fail results of the diagnostic tests run during POST via LED
activity, the error log, or CLI using the errShow command. For more information
about error messages, refer to the hp StorageWorks Fabric OS Version 3.0.x/4.0.x
Reference Guide.
