System Configuration
6. Remove any “CB” entries that provide access to individual users from the /etc/password file locally
on the ContentBridge and file under /tftpboot/config/gateway on all
ContentDirectors.
Open /etc/password and delete entries for the same individual users (the entries do not contain
“CB” in this file).
NOTE: In order to access the MediaGrid, the individual users must be added to the Active Directory domain.
7. Add the following line to the ContentBridge configuration file. This can be done via SystemManager
or by editing /tftpboot/config/gateway/ manually on ALL ContentDirectors.
NATIVE
Replace with the hostname of the ContentBridge.
8. Restart the gateway service:
service gateway restart
9. Repeat steps 1-8 for all remaining ContentBridges in the MediaGrid cluster.

Adding the Omneon MediaGrid Devices to the Local DNS
An entry for each of the Omneon MediaGrid devices below must be added to the customer’s DNS for
client access of the Omneon MediaGrid system. This will result in the DNS providing a round-robin
allocation of the IP addresses when requested.
Contact the customer network administrator to complete these procedures.
The following entries must be added to the local DNS:
• The ContentDirector names as well as the IP addresses of each public interface.
• The ContentBridge (if present in the system) name and IP address.
• The SystemManager name and IP address.
• The Omneon MediaGrid name, which should be associated with the public IP addresses of all the
ContentDirectors. This name is distinct from the individual names of the ContentDirectors.
The ContentDirectors work together in a manner similar to a cluster. Because of this clustering type of
operation, clients can connect to any of the ContentDirectors. In order for this to happen, the
customer’s DNS must have the IP addresses of each of the ContentDirectors added (with the same
name). These address records (type A) should have a low TTL value (60 second range) due to caching
considerations.
Note that each ContentDirector has two ports for client access, which means that there will be two
address entries in the DNS for each ContentDirector. Since the DNS uses a cyclic round robin
allocation technique, the address records should be in the DNS in the following order:
