Chapter 4 System Configuration
To configure the remote Media API:
1. Obtain copies of ommcp.exe and ommedia.dll from Harmonic.
2. Ensure that the ContentBridge is configured correctly. Following is an example setup:
Spectrum Server hostname (or IP): om-spect Filesystem name /fs0
Content Director hostname (or IP): om-cld Filesystem name /mg0
Content Bridge hostname (or IP): 10.3.1.40 serial number: CLB01523
NOTE: Short hostnames are supported in the ContentBridge configuration file if the hostname has the
same domain name as the Harmonic MediaGrid system being configured. Otherwise, a fully qualified
domain name (FQDN) must be specified in the configuration file if you wish to use hostnames. Note that
remote ommcp's will only work using the exact hostname or IP address specified in the configuration file.
3. Make sure that the desired mount type(s) is specified in the ContentBridge configuration boot
file /tftpboot/config/gateway/<serial number> across all ContentDirectors. Note that on a
ContentBridge there are three different types of remote mounts utilized. "CB" (ContentBridge)
mounts are used for configuring a ContentBridge to share out a file system from a specific
Harmonic MediaGrid cluster via CIFS, FTP, and NFS. The other two types of mount points are
utilized only for the Remote Media API. They define remote systems that will be used to
transfer media files. "MG" (Harmonic MediaGrid) mounts are for configuring remote Harmonic
MediaGrid file systems. "CI" (CIFS) mounts are for configuring remote Spectrum servers, or
other generic CIFS servers. The following shows the syntax for the configuration boot file:
MEDIA_API=YES
MG hostname filesystem_name <username> <password>
CI hostname share_name <username> <password>
Refer to Editing the ContentBridge Configuration File in the Harmonic SystemManager User
Guide for more information.
NOTE: Username and password are required parameters for Harmonic MediaGrid (MG) mounts. Username
and password are optional for CIFS (CI) mounts to Spectrum systems, or other servers that allow
anonymous CIFS access. If a hostname is specified, a mount will be made, however, remote ommcp's work
solely on the hostname or IP address specified in the config file on the ContentDirectors. Multiple MG and
CI mounts are allowed.
4. Once you have edited the configuration file, save it and reboot the ContentBridge.
5. Using a client such as PuTTY, start an SSH session to the ContentBridge and type the
following command:
df
Sample output showing mount points created follows:
Filesystem
//om-spect/fs0
/om-cld/mg0
NOTE: Harmonic MediaGrid mounts have a single slash and CIFS/Spectrum mounts have double slashes
under the file system column.
6. Type the following command:
service ommedia status
Your response should be similar to:
[root@CLB04130 ~]# service ommedia status ommedia_remote_svc (pid
4552) is running...
ommedia_mon.sh (pid 4549 4548) is running...
