POST and boot specifications
When the switch is turned on or rebooted, the switch performs POST. Total boot
time with POST is up to 3 minutes. POST can be omitted after subsequent reboots
by using the
fastboot
command or entering the
diagDisablePost
command to
persistently disable POST.
For more information about these commands, refer to the
Fabric OS Command
Reference
.
POST
The success or 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:
1.
Preliminary POST diagnostics are run.
2.
Operating system is initialized.
3.
Hardware is initialized.
4.
Diagnostic tests are run on several functions, including circuitry, port
functionality, memory, statistics counters, and serialization.
Boot
In addition to POST, boot includes the following steps after POST is complete:
1.
Universal port configuration is performed.
2.
Links are initialized.
3.
Fabric is analyzed, and if any ports are connected to other switches, the switch
participates in a fabric configuration.
4.
Switch obtains a domain ID and assigns port addresses.
5.
Unicast routing tables are constructed.
6.
Normal port operation is enabled.
