How to Configure Internet Protocol (IP) Network Multipathing Groups

Perform this task on each node of the cluster.

All public network adapters must belong to an IP Network Multipathing group.

1. Have available your completed “Public Networks Worksheet” in Sun Cluster 3.1 Release Notes.

2. Configure IP Network Multipathing groups.

   Perform procedures for IPv4 addresses in “Deploying Network Multipathing” in IP Network Multipathing Administration Guide or “Administering Network Multipathing (Task)” in System Administration Guide: IP Services Also follow these guidelines for IP Network Multipathing groups in a Sun Cluster configuration:

   • Each public network adapter must belong to a multipathing group.

   • The local-mac-address? variable must have a value of true for Ethernet adapters. This is a change from the requirement for Sun Cluster 3.0 software.

   • You must configure a test IP address for each multipathing group adapter.

   • Test IP addresses for all adapters in the same multipathing group must belong to a single IP subnet.

   • Test IP addresses must not be used by normal applications because they are not highly available.

   • There are no requirements or restrictions for the name of a multipathing group.

3. Do you intend to change any private hostnames?

   • If yes, go to How to Change Private Hostnames.

   • If no, go to Step 4.

4. Did you install your own /etc/inet/ntp.conf file before you installed Sun Cluster software?

   • If no, go to How to Configure Network Time Protocol (NTP) to install or create the NTP configuration file.

   • If yes, go to Step 5.

5. Do you intend to use Sun Management Center to configure resource groups or monitor the cluster?

   • If yes, go to Installing the Sun Cluster Module for Sun Management Center.

   • If no, install third-party applications, register resource types, set up resource groups, and configure data services. See the documentation supplied with the application software and the Sun Cluster 3.1 Data Service Planning and Administration Guide.
