Displaying the zone definition for the replication network domain

Each network in HCP is associated with a domain. Multiple networks can be associated with the same domain. If you’re using DNS for domain name resolution, the DNS needs to include a zone definition for each combination of network and domain.

If an HCP system is involved in replication, the zone definition for the replication network domain for that system needs to be added to the upstream DNS servers for the other system on the replication link. An upstream DNS server is a DNS server to which HCP routes the outbound communications it initiates (for example, for sending log messages to syslog servers or for communicating with Active Directory).

If the domain for the replication network is shared with other networks, the domain name in the zone definition you add for the replication network domain must be:

replication.admin.replicaton-network-domain-name

From the Replication page, you can display the zone definition for the replication network domain, formatted for Unix DNS servers. You can then copy that definition to the upstream DNS servers.

Note: You can display the zone definition only while virtual network management is enabled for the HCP system and only if at least one user-defined network exists.

To display the zone definition:

1.In the top-level menu in the HCP System Management Console, mouse over Services to display a secondary menu.

2.In the secondary menu, click on Replication.

3.On the left side of the Replication page, click on Settings.

4.On the replication Settings page, click on Zone Definition.

The Zone Definition section opens. This section shows the zone definition for the network (with a type of slave or stub, as applicable), formatted as shown in this example:

# net1 Special-purpose HCP system network
zone "replication.admin.system_1.example.com" IN {
type slave;
file "/var/named/slave/replication.admin.system_1.example.com";
masters {
172.25.147.11;
172.25.147.12;
172.25.147.13;
172.25.147.14;
};
};
