Creating a cluster
For an independent disk pool to be switchable among systems or for geographic mirroring to be enabled, a cluster is required.
A cluster is a collection or group of one or more systems that work together as a single system. For complete documentation on clusters and how they work, see Clusters.
There are multiple ways to create and manage a cluster. You can use iSeries™ Navigator to create a cluster, a cluster middleware business partner solution, or IBM® cluster commands and APIs. See Solutions for configuring clusters for a complete look at the options for configuring and managing clusters.
To create a cluster for use with switchable independent disk pools:
- Create a cluster.
- Verify that all nodes are at the correct potential cluster version. Potential cluster version must be at least 3 for switchable independent disk pools that support libraries. To allow for the V5R3M0 capability of geographic mirroring, the potential cluster version must be set to at least 4.
- Start all nodes in the cluster, or at least those that will be in the device domains.
