How to Configure Additional Public Network Adapters

If the nodes in the cluster are connected to more than one public subnet, you can configure additional public network adapters for the secondary subnets. This task is optional.

Configure only public network adapters, not private network adapters.

1. Have available your completed "Public Networks Worksheet" from the Sun Cluster 3.0 Release Notes.

2. Become superuser on the node to configure for additional public network adapters.

3. Create a file named /etc/hostname.adapter, where adapter is the adapter name.

   Note -

   In each NAFO group, an /etc/hostname.adapter file should exist for only one adapter in the group.

   ---

4. Type the hostname of the public network adapter IP address in the /etc/hostname.adapter file.

   The following example shows the file /etc/hostname.hme3, created for the adapter hme3, which contains the hostname phys-schost-1.

   # vi /etc/hostname.hme3 phys-schost-1

5. On each cluster node, ensure that the /etc/inet/hosts file contains the IP address and corresponding hostname assigned to the public network adapter.

   The following example shows the entry for phys-schost-1.

   # vi /etc/inet/hosts ... 192.29.75.101 phys-schost-1 ...

   Note -

   If you use a naming service, this information should also exist in the naming service database.

   ---

6. On each cluster node, turn on the adapter.

   # ifconfig adapter plumb # ifconfig adapter hostname netmask + broadcast + -trailers up

7. Verify that the adapter is configured correctly.

   # ifconfig adapter

   The output should contain the correct IP address for the adapter.

8. Configure PNM and set up NAFO groups.

   Go to "How to Configure Public Network Management (PNM)".

   Each public network adapter to be managed by the Resource Group Manager (RGM) must belong to a NAFO group.
