Contentbridge Configuration Parameters; Enabling Or Disabling Cifs Oplocks - Harmonic MediaGrid Installation And Configuration Manual

Chapter 4 System Configuration
5. The configuration script asks a series of questions requiring information specific to the
customer site. Use the information from the Harmonic MediaGrid Installation Planning Guide
specific to your Harmonic MediaGrid system to complete the answers. Note that the assistant
will display suggested responses in brackets. During the assistant, you can use the up or
down arrow keys to tab to previous responses.
The configuration assistant may provide a different IP address for the High Bandwidth
ContentBridge than the one you wish to use. If so, when the configuration script asks you to
confirm the system configuration, indicate NO. Then you can enter the desired IP address.
6. When prompted, insert a USB drive. The configuration assistant automatically copies the
configuration information to the USB drive.
7. Type the following command to copy the configuration information to this High Bandwidth
ContentBridge:
sudo ./copyconfigs -m
8. When prompted to enter the ID of the High Bandwidth ContentBridge in the specified range,
make sure to select the ID of the ContentBridge you are adding or replacing. If you are unsure
of the correct ID, you may consider re-running the Configuration Assistant and manually
setting the IP address of the High Bandwidth ContentBridge during the configuration.
9. Once copying is complete, remove the USB drive from the High Bandwidth ContentBridge.
10. Type the following command to remove the High Bandwidth ContentBridge from the
FIRSTBOOT mode:
sudo initconfig --rmflag

ContentBridge Configuration Parameters

A configuration file exists for all ContentBridges. The configuration file enables you to configure
parameters to:
Set up user access to files and directories

Set up file transfers, including transfer of growing files

Tune performance

See the Harmonic SystemManager User Guide for instructions on editing the ContentBridge
configuration file.

Enabling or Disabling CIFS Oplocks

Disabling CIFS oplocks improves data integrity for highly concurrent applications that use file
locking. The setting is disabled by default. This option only affects the operation of CIFS on a
ContentBridge.
Set this parameter in the configuration file on all ContentDirectors in a cluster in /tftpboot/
config/config or in the /etc/gateway.conf file for a high bandwidth ContentBridge. Add the
following line to the configuration file to disable CIFS oplocks:
CIFS_OPLOCKS=NO
The acceptable options are "YES", "NO".
