Restoring NVRAM Configuration
Variables
If for any reason, the flash PROM update process did not complete successfully, for
example if you lost power, you may have to restore
diag-switch?
to its default
value of false and restore any customized values to the other NVRAM configuration
variables.
Note – Use the steps in this section only if for any reason your NVRAM
configuration variables were not reset to their customized values or if
diag-
switch?
was not set to its proper value.
1. Reboot the system by typing
reboot
at the prompt.
If
diag-switch?
was set to true and the system is power cycled, diagnostics will be
run. Running diagnostics could take several minutes. Also, the system will attempt
to boot from the network once the diagnostics have completed running.
Note –
Other NVRAM variables may be reset to their default values, which could
affect the system in other ways. For example, if you ran the flash PROM update
through the serial port and the system still has its keyboard plugged in, you will no
longer get any response from the serial port connection. The firmware will be
waiting for input from the keyboard.
2. As the system boots, go to the
ok
prompt by one of the following methods.
■
Press Stop-a from the keyboard.
■
If you are running on a terminal and connected to serial port A of the system,
press the Break key.
■
If you are connected to serial port A via telnet connection send a Break
sequence by pressing the Control and ] keys simultaneously. This returns you
to the telnet command line. Type
send brk
at the telnet command line.
■
If you are connected to serial port A via a tip connection, send a Break
sequence by typing the characters ~# in quick succession.
