4 Solving Problems

This chapter helps you identify and solve problems that might occur while you are using the
system.

Resetting the System

To do this:
Soft boot reset, which clears system memory and reloads the
operating system.
Cold boot reset. Turn the system power off and then on. This
clears system memory, restarts POST, reloads the operating
system, and halts power to all peripherals.

Fault Resilient Booting

Fault resilient booting insures the system will not stop from a boot problem. Two sets of timers are
implemented in the BMC that will automatically reset the system if the system should halt for some
reason.
•
FRB 2 - 5 sec timer. If the primary processor does not come up in 5 seconds the system will
automatically reset and switch to the secondary processor (if installed). If a second processor is
not installed, the system will try to restart off the primary processor.
•
FRB 3 - 7 minute timer. If the system does not make it up to the end of POST in 7 minutes, the
system will automatically reset and try again. It is assumed that the processor failed regardless
of what may have caused the system to hang. The primary processor is taken off line and the
system will boot off the secondary (if installed otherwise it will try to restart again off of the
primary). Bad memory or a bad plug in card may cause an FRB 3 failure.
All failures are logged to the system event log.
The system will remember all FRB errors and display them at the end of POST until you select the
Processor Retest option from the BIOS Setup utility.

Initial System Startup

Incorrect installation or configuration usually causes problems that occur at initial system startup.
Hardware failure is a less frequent cause.
