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.
The Brocade 16Gb FC Switch Module 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, 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.
The success and failure results of the diagnostic tests that run during POST can be monitored through the error log or the CLI.
POST includes the following:
Running preliminary POST diagnostics
Initializing the operating system
Initializing hardware
Running diagnostic tests on several functions, including circuitry, port functionality, memory, statistics counters, and serialization
Boot completes in approximately three minutes if it is run. Boot includes the following tasks after POST completes:
Universal ports are configured
Links are initialized
Fabric is analyzed; if any ports are connected to other switches, the Brocade 16Gb FC Switch Module participates in a fabric configuration
The Brocade 16Gb FC Switch Module obtains a domain ID and assigns port addresses
Unicast routing tables are constructed
Normal port operation is enabled
To determine whether POST completed successfully and whether any errors were detected:
Verify the Brocade 16Gb FC Switch Module LEDs
indicate all components are healthy. For a description and interpretation
of LED patterns, see Port link status LED patterns.
If one or more LEDs do not display a Healthy state, use the switchshow command
to verify the LEDs on the switch are not set to beacon.
Verify the Brocade 16Gb FC Switch Module 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 the Brocade 16Gb FC Switch Module still does not complete POST successfully, contact your Hewlett Packard Enterprise representative.
Any errors detected during POST are written to the system log. Use the errshow command to review the system log.
For information about all referenced commands and accessing the error log, see the latest version of the Fabric OS Administrator Guide. For information about error messages, see the Fabric OS System Error Messages Reference Manual.
