Interpreting POST Results
Each time the switch is powered on or reset, the switch automatically
performs POST, a system check during which LED patterns may vary.
To verify that 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”
on
page 54
. Use the
slotShow
command to check the status of the slots.
For information about setting a switch to beacon, refer to the
hp
StorageWorks fabric os procedures guide
.
•
Verify that the switch prompt displays when POST completes. If it does
not display, POST was not successfully completed. Contact HP support.
•
Review the system log. Any errors detected during POST are written to
the system log, accessible through the
errShow
command. For
information about error messages, refer to the
hp StorageWorks
diagnostic and system error message reference
.
