HP Brocade 4Gb SAN Switch for HP BladeSystem p-Class - Manual (Page 166)

166 Working with diagnostic features
POST1 cannot be bypassed; it runs from the boot loader. The factory default configuration is also set to
run POST2, but you can configure your switch to bypass POST2, which runs after the kernel image has
started but before general system services, such as login, are enabled.
Although each test performed during POST2 is configurable, modify a POST2 test only if directed by your
switch provider’s customer service representative.
You can use the
diagdisablepost
command to disable POST2, and you can reenable it using the
diagenablepost
command. Refer to the HP StorageWorks Fabric OS 4.x command reference guide
for additional information about these commands.
The following example shows a typical boot sequence, including POST messages:
If you choose to bypass POST2, or after POST2 completes, various system services are started and the
boot process displays additional console status and progress messages.
Viewing switch status
Use the
switchstatusshow
command to display the overall status of the switch, including its power
supplies, fans, and temperature. If the status of any one of these components is either marginal or down,
the overall status of the switch is also displayed as marginal or down. If all components have a healthy
status, the switch displays a healthy status.
The rules used to classify the health of each component are in the configuration files. To change the rules,
you must use the
configupload
command to copy the configuration files, edit them manually, and use
the
configdownload
command to load them back to the switch.
To view the overall status of the switch:
1. Connect to the switch and log in as admin.
