Changing Boot Parameters

You can access and edit boot parameters by using either the ACLI or by interrupting the system boot process.

Note:

Changes to boot parameters do not go into effect until you reboot the system.

Change Boot Parameters from the ACLI

To access and change boot parameters from the ACLI:

In Superuser mode, type configure terminal, and press Enter.
```
ORACLE# configure terminal
```
Type bootparam, and press Enter. The boot device parameters display.
```
ORACLE(configure)# bootparam
'.' = clear field;  '-' = go to previous field;  q = quit
Boot File	: /boot/nnScz100.bz
```
To navigate through the boot parameters, press Enter and the next parameter appears on the following line.

You can navigate through the entire list this way. To go back to a previous line, type a hyphen (-) and press Enter. Any value that you enter entirely overwrites the existing value and does not append to it.
To change a boot parameter, type the new value that you want to use next to the old value. For example, if you want to change the image you are using, type the new filename next to the old one. You can clear the contents of a parameter by typing a period and then pressing Enter.
```
ORACLE(configure)# bootparam
'.' = clear field;  '-' = go to previous field;  q = quit

Boot File	: /boot/nnSCz100.bz /boot/nnSCz200.bz
```
When you have scrolled through all of the boot parameters, the system prompt for the configure terminal branch displays.
```
NOTE: These changed parameters will not go into effect until reboot.
Also, be aware that some boot parameters may also be changed through
PHY and Network Interface Configurations.

ORACLE(configure)#
```
Exit the configure terminal branch.
Reboot the system for the changes to take effect.
The ACLI reboot and reboot force commands initiate a reboot. With the reboot command, you must confirm that you want to reboot. With the reboot force command, you do not have make this confirmation.
```
ORACLE# reboot force
```
The system completes the full booting sequence. If necessary, you can stop the auto-boot at countdown to fix any boot parameters.

If you configured boot parameters correctly, the system prompt displays and you can go ahead with configuration, management, or monitoring tasks.
Note:
If you configured the boot parameters incorrectly, the system goes into a booting loop and displays an error message. Press the space bar to stop the loop. Correct the error in the boot parameter, and reboot the system.

Change Boot Parameters by Interrupting a Boot in Progress

To access and change boot parameters by interrupting a boot in progress:

When the system is in the process of booting, you can press the space bar on your keyboard to interrupt when you see the following message appear:
```
Press the space bar to stop auto-boot...
```
After you stop the booting process, you can enter the letter p to display the current parameters, the letter c to change the boot parameters or the @ (at-sign) to continue booting.
```
[Boot]: c
'.' = clear field;  '-' = go to previous field;  q = quit
Boot File	: /boot/nnScz100.bz
```
To navigate through the boot parameters, press Enter and the next parameter appears on the following line.

You can navigate through the entire list this way. To go back to a previous line, type a hyphen (-) and press Enter. Any value that you enter entirely overwrites the existing value and does not append to it.
To change a boot parameter, type the new value that you want to use next to the old value. For example, if you want to change the image you are using, type the new filename next to the old one.
```
'.' = clear field;  '-' = go to previous field;  q = quit

Boot File	: /boot/nnSCz100.bz /boot/nnSCz200.bz
```
After you have scrolled through the complete list of boot parameters, you return to the boot prompt. To reboot with your changes taking effect, type @ (the at-sign), and press Enter.
```
[Acme Packet Boot]: @
```
The system completes the full booting sequence, unless there is an error in the boot parameters.

If you have configured boot parameters correctly, the system prompt displays and you can go ahead with configuration, management, or monitoring tasks.

Note:
If you have configured the boot parameters incorrectly, the system goes into a booting loop and displays an error message. Press the space bar to stop the loop. Correct the error, and reboot your system.
