Administering the Public Network

Oracle Solaris Cluster software supports the Oracle Solaris software implementation of Internet Protocol network Multipathing (IPMP) for public networks. Basic IPMP administration is the same for both cluster and noncluster environments. Multipathing is automatically installed when you install the Oracle Solaris 11 OS, and you must enable it to use it. Multipathing administration is covered in the appropriate Oracle Solaris OS documentation. However, review the guidelines that follow before administering IPMP in an Oracle Solaris Cluster environment.

How to Administer IP Network Multipathing Groups in a Cluster

Before performing IPMP procedures on a cluster, consider the following guidelines.

For more information about IP Network Multipathing, see the appropriate documentation in the Oracle Solaris OS system administration documentation set.

Table 7-3 Task Map: Administering the Public Network

Oracle Solaris OS Release
Instructions
Oracle Solaris 11 OS

For cluster software installation procedures, see the Oracle Solaris Cluster Software Installation Guide. For procedures about servicing public networking hardware components, see the Oracle Solaris Cluster 4.1 Hardware Administration Manual.

Dynamic Reconfiguration With Public Network Interfaces

You must consider a few issues when completing dynamic reconfiguration (DR) operations on public network interfaces in a cluster.


Caution

Caution - For multipathing groups with two adapters, if the remaining network adapter fails while you are performing the DR remove operation on the disabled network adapter, availability is impacted. The remaining adapter has no place to fail over for the duration of the DR operation.


Complete the following procedures in the order indicated when performing DR operations on public network interfaces.

Table 7-4 Task Map: Dynamic Reconfiguration With Public Network Interfaces

Task
Instructions
1. Switch the IP addresses from the adapter to be removed to another adapter in the multipathing group, using the if_mpadm command
2. Remove the adapter from the multipathing group by using the ipadm command
3. Perform the DR operation on the public network interface
