Post, Boot, Interpreting post results – HP Brocade 8Gb SAN Switch for HP BladeSystem c-Class User Manual
Page 24: Firmware update, Post boot interpreting post results
POST can be omitted for subsequent reboots by using the fastboot command. For more
information about this command, see the latest version of the Fabric OS Command Reference
Guide. If you suspect a problem with the switch, enable POST to obtain more information on any
failure.
POST
The success/failure results of the diagnostic tests that run during POST can be monitored through
the error log or the command line interface.
POST includes the following steps:
•
Running preliminary POST diagnostics
•
Initializing the operating system
•
Initializing the hardware
•
Running diagnostic tests on several functions, including circuitry, port functionality, memory,
statistics counters, and serialization
Boot
Boot completes in approximately three minutes if POST is run, and includes the following tasks
after POST completes:
•
Universal port configuration
•
Links initialized
•
Fabric analysis; if any ports are connected to other switches, the 8Gb SAN Switch participates
in a fabric configuration.
•
The 8Gb SAN Switch obtains a domain ID and assigns port addresses.
•
Unicast routing tables constructed
•
Normal port operation enabled
Interpreting POST results
To determine whether POST completed successfully and whether any errors were detected:
1.
Verify that the 8Gb SAN Switch LEDs indicate all components are healthy. See
for descriptions and interpretations of LED patterns. If one or more LEDs do not display a
Healthy state, use the switchshow command to verify that the LEDs on the switch are not set
to beacon.
2.
Verify that the 8Gb SAN Switch prompt appears 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 appear, try opening another Telnet session or another management
tool. If this is not successful, the 8Gb SAN Switch did not successfully complete POST; contact
HP.
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 accessing the error log, see the latest
version of the HP StorageWorks Fabric OS Administrator Guide. For information about error
messages, see the Fabric OS System Error Messages Reference Manual.
