Creating a peer domain

Edit online

Follow these instructions to configure nodes into an RSCT peer domain.

Before creating a peer domain, review the information in Prerequisites and restrictions when using configuration resource manager commands.
In a peer domain, processor architectures and operating systems are heterogeneous. A peer domain can contain one of these node sets:
  • AIX® nodes, which support any processor architecture that is supported by the AIX operating system.
  • Linux® nodes.
  • Solaris nodes.
  • Windows nodes.
  • A combination of AIX nodes and Linux nodes.
Note: AIX nodes and Solaris nodes cannot be part of the same peer domain.

Programs that run in a peer domain might not support the same heterogeneous environment as RSCT. See the specific user documentation for information about supported processor architectures and operating systems.

To configure nodes into an RSCT peer domain, you must first prepare the initial security environment on each node of the peer domain, then create a peer domain definition, and then bring the domain online.

Note: When creating a peer domain that operates on Cluster Aware AIX (CAA) linked clusters, the CAA commands must be used to define the cluster to provide site information.
