Managing the SAN Switches 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 are listed 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. See Table 11 on page 63 for description and interpretation of LED patterns. If one or more LEDs do not display a healthy state, verify that the LEDs on the switch are not set to "beacon"; use 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 switch supplier for repair. 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 Fabric OS Procedures 4.2x User Guide. For information about error messages, refer to the HP StorageWorks Diagnostic and System Error Messages 4.2.x Reference Manual. 66 SAN Switch 2/8V, 2/16V and 2/16N 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 are listed 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. See
Table 11
on page 63 for description and interpretation of LED patterns. If one
or more LEDs do not display a healthy state, verify that the LEDs on the
switch are not set to “beacon”; use 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
switch supplier for repair.
3.
Review the switch system log for errors. Any errors detected during POST are
written to the system log, accessible through the
errshow
command.
