Interpreting POST and boot results
The SAN768B-2 performs power on self test (POST) by default each time the
system is powered on, rebooted, or reset. The system can be rebooted using the
reboot
(to reboot each CP individually), or
fastBoot
commands. The
fastBoot
command reboots the system without running POST. If the active CP blade is
rebooted, it fails over to the standby CP blade.
POST
The system automatically performs POST each time the chassis is powered on,
rebooted, or reset. The chassis can be rebooted using the
reboot
(to reboot each CP
individually) or
fastBoot
commands. The
fastBoot
command reboots the switches
without running POST. If the active CP blade is rebooted, it fails over to the
standby CP blade.
To verify that POST has completed without error:
v
Verify that all LEDs return to a normal state after POST completes (see
Chapter 4, “Monitoring system components,” on page 53).
If one or more LEDs do not return to a normal state, and this is not due to the
SAN768B-2 being set to beacon, refer to the relevant LED table to identify and
correct the problem. For port blades, CP blades, and core switch blades, the
slotShow
command can be used to check the status of the slots. For information
about turning beaconing on/off, refer to the Fabric OS Administrator's Guide .
v
Verify that the switch prompt displays when POST completes.
If it does not display, POST was not successfully completed. Contact IBM for
support.
v
Review the system error log using the
errShow
or
errDump
commands.
v
Any errors detected during POST are written to the system log, which is
accessible through the
errShow
command. For information about error messages,
refer to the Fabric OS Message Reference .
POST includes the following steps:
1. Preliminary POST diagnostics are run.
2.
Operating system is initialized.
