Storage Expansion Module Use With Local CDRs / FTP Push

Storage Expansion Module Use With Local CDRs FTP Push

The Oracle suite of engineered systems can be configured with an optional Storage Expansion Module that extends the system's internal storage beyond the fixed amount of flash RAM. When configuring local CDR creation, you can configure the OCSBC to use the Storage Expansion Module for local CDR files instead of the limited internal flash RAM.

Disk space on the Storage Expansion Module appears as a local volume on the OCSBC. Wherever you specify a volume name for a configuration parameter value, you can enter a volume located on the Storage Expansion Module, (unless the parameter is otherwise specified).

Local CDR Storage Directory

To save local CDR files to the Storage Expansion Module, configure the file path parameter in the account config with a volume and directory located on the Storage Expansion Module.

FTP Push Backup

When FTP push is enabled, if all FTP push servers are unreachable, then local CDR files are written to local file system until the FTP push servers return to service. Once an FTP Push server becomes reachable, the OCSBC transfers all local CDR files to the remote server automatically. After all local CDR files have been successfully transferred to the FTP server from the OCSBC, they are deleted from the local volume.

Local CDR File Compression

You can configure the OCSBC to compress local CDRs in zip format to save disk space. The local CDRs will be compressed and appear with a .zip file extension. This feature is enabled with the cdr compression parameter.

ACLI Configuration and Examples

The following ACLI configuration procedure describes:

identifying volumes on the Storage Expansion Module
configuring Storage Expansion Module volumes as the destination for local CDR files

These procedures are only a portion of local CDR file generation and FTP Push configuration. Please refer to the Local CDR Storage and FTP Push section for a full explanation and all prerequisites before referencing the following procedure.

Identify Volumes

To identify the volumes on the Storage Expansion Module to use with local CDR storage:

Note the volume name on the Storage Expansion Module you wish to use for local CDR output using the show space hard-disk command.
```
SYSTEM# show space hard-disk
/opt: 19695716352/19695749120 bytes (99%) remaining
/opt/logs: 19693335040/19693367808 bytes (99%) remaining
SYSTEM#
```
Note:
The check-space-remaining hard-disk command is identical to the show space hard-disk command.

Configure File Path

To configure an Oracle Communications Session Border Controller to write local CDRs to the Storage Expansion Module:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter.
```
ORACLE(configure)# session-router
```

Type account-config and press Enter.

ORACLE(session-router)# account-config
ORACLE(account-config)#

file-path—Set this parameter to the volume you identified to use for local CDR file storage in the previous section. Ensure the path begins with a forward slash, /.
Save and activate your configuration.
