Post Specifications
The HP StorageWorks Core Switch 2/64 performs POST by default each
time the chassis is powered on (cold boot) or the switch is rebooted. The
switch can be rebooted using the
switchreboot, reboot, or fastboot
commands. The
fastboot command reboots the switches without running
POST. A CP card failover event results in a reboot for the affected CP card.
POST includes a number of diagnostic tests. Test results can be monitored
through LED activity, the error log, or command-line interface. POST
requires a minimum of three minutes to complete and may vary depending
on the devices connected to the switch.
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 a number of functions, including internal
connections and circuitry, port functionality, ability to send and receive
frames, all aspects of memory, parity, statistics counters, and correct
serialization.
The following switch initialization steps are performed whether or not
POST is run:
1. Universal Port configuration is performed.
2. Links are initialized.
3. Fabric is analyzed. If ports are connected to other fabric elements
(switches), the switch will participate in a fabric configuration.
4. The switch will obtain a domain ID and assign port addresses.
5. Unicast routing tables are constructed.
6. Normal port operation is enabled.
Full initialization takes a minimum of 5 minutes.
