POST and boot speci
fi
cations
POST is a system check that is performed each time the switch is powered on, rebooted, or reset. During
POST, the LEDs
fl
ash different colors. Any errors that occur during POST are listed in the error log.
The 8Gb SAN Switch performs POST when it is turned on or rebooted. Total boot time with POST is
approximately three minutes.
POST can be omitted for subsequent reboots by using the
fastboot
command. For more information
about this command, refer to 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:
•
Preliminary POST diagnostics are run.
•
Operating system is initialized.
•
Hardware is initialized.
•
Diagnostic tests are run on several functions, including circuitry, port functionality, memory,
statistics counters, and serialization.
Boot
Boot completes in approximately three minutes if POST is run. Boot includes the following tasks after
POST completes:
•
Universal port con
fi
guration
•
Links initialized
•
Fabric is analyzed; if any ports are connected to other switches, the 8Gb SAN Switch participates
in a fabric con
fi
guration
•
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
Table 16
, page 35
for description and interpretation 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”.
