Booting an Image

Booting an Image on Your Oracle Communications Session Border Controller

You can either boot your SBC from the system’s local storage or from an external device. Both locations can store images from which the system can boot. This section describes both booting methods.

For boot parameters to go into effect, you must reboot your SBC. Since a reboot stops all call processing, Oracle recommends performing tasks that call for a reboot during off-peak hours. If your SBCs are set up in an HA node, you can perform these tasks on the standby system first.

Note:

Only the local admin user can SFTP a boot image to the /boot directory.

Use the local admin user account to SFTP your boot image to the /boot directory or use a supplementary administrator user account (such as a TACACS+ or RADIUS administrator) to upload your boot image to the /code/images directory. Then set the Boot File parameter to your uploaded boot file.

Boot Parameter Definitions

The system displays all boot parameters when you configure them after a boot interrupt. The system hides some boot parameters from the ACLI so that you do not attempt to configure them. If changed improperly, these parameters can cause the system to sop responding.

The following table defines each of the parameters that the system displays when you perform configuration after a boot interrupt.

Boot Parameter	Description
Boot File	The name and path of the software image you are booting. Include the absolute path for a local boot from the local /boot volume and for a net boot when a path on the FTP server is needed.
IP Address	IP address of wancom0.
VLAN	VLAN of management network over which this address is accessed. Note: VLANs over management interfaces are supported only on the Acme Packet 1100. Note: The acquire-config command is not supported on management interfaces that use both VLANs and IPv6.
Netmask	Netmask portion of the wancom0 IP Address.
Gateway	Network gateway that this wancom0 interface uses.
IPv6 address	Version 6 IP address/mask of wancom0. Configure the mask as a forslash (/) after the address followed by the mask in number of bits.
IPv6 Gateway	Version 6 network gateway that this wancom0 interface uses.
Host IP	IP Address of FTP server from which to download and execute a software image.
FTP Username	FTP server username
FTP password	FTP server password
Flags	Codes that signal the system from where to boot. Also signals the system about which file to use in the booting process. This sequence always starts with 0x (these flags are hexadecimal).
Target Name	Name of the Oracle Communications Session Border Controller as it appears in the system prompt. For example, ORACLE> or ORACLE#. You need to know the target name if you are setting up an HA node. This name must be unique among Oracle Communications Session Border Controllers in your network. This name can be 63 characters or less.
Console Device	Serial output device type, dependent on platform. COM1 applies to virtual serial consoles, VGA to virtual video console. VGA is the default on VMware and KVM. COM1 is the default on OVM .
Console Baud Rate	The speed in bits per second which the console port operates at. It operates at 115200 BPS, 8 data bits, no stop bit, parity NONE.
Other	Allows miscellaneous and deployment-specific boot settings.

Booting from Local Storage

Once you have installed an image, you can boot your Oracle Communications Session Border Controller from its local storage.

To boot from your local storage:

Confirm that the boot parameters are set up correctly and make any necessary changes.
You can check the boot configuration parameters by accessing the bootparam command from the configure terminal menu.
```
ORACLE# configure terminal
ORACLE# bootparam
```
Change any boot configuration parameters that you need to change. It is especially important to change the file name boot configuration parameter. The file name parameter needs to use the /boot value so that the Oracle Communications Session Border Controller boots from the local storage.

You can boot from a different image files using the l (small letter L) option from the boot menu prompt. This allows you to select an alternate image file when the boot file gets corrupted. This option is available only when FIPS mode is disabled. You can view the files in a page view when there are more than 15 files in the directories. When Oracle Communications Session Border Controller boots over network using ftp/sftp with the selected image file, this option does not update the boot param. This option displays image files from both /boot and /code/images directories irrespective of R226 license.
