26 Netra 240 Server Service Manual • June 2004
7. If you have not done so already, disable the OpenBoot automatic boot operation:
You must set the auto-boot? variable to false and issue the reset-all
command to ensure that the system correctly initiates upon reboot. If you do not
issue these commands, the system might fail to initialize, because the boot process
was aborted in
Step 6.
8. (Optional) Re-enable the OpenBoot automatic boot operation:
Set the auto-boot? variable back to true so that the system boots automatically
after a system reset.
9. At the ok prompt, type the following command:
The boot -r command rebuilds the device tree for the system, incorporating any
newly installed options so that the operating system recognizes them.
Note – The system banner takes anywhere from 30 seconds to 5 minutes to appear.
The time depends on the system configuration (number of CPUs, memory modules,
PCI cards) and the level of POST and OpenBoot Diagnostics tests being performed.
For more information about OpenBoot configuration variables, see Appendix C.
10. Turn the rotary switch to the Locked position.
This prevents anyone from accidentally powering off the system.
The system server status LED indicators provide power-on status information. For
information about the system LEDs, see
“Front Panel Indicators” on page 8.
If the system encounters a problem during startup, and the rotary switch is in the
Normal position, restart the system in diagnostics mode to determine the source of
the problem. Turn the rotary switch to the Diagnostics position and power cycle the
system. See
“Powering Off the Server” on page 22.
For information about system diagnostics tools, see the Netra 240 Server System
Administration Guide (817-2700).
