Create a cluster

For an independent disk pool to be switchable among servers or for geographic mirroring to be enabled, an iSeries™ cluster is required. An iSeries cluster is a collection or group of one or more servers that work together as a single server. For complete documentation on clusters and how they work, see Clusters.

There are multiple way 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:

  1. For step-by-step instructions on how to create a cluster, see Create a cluster in the Clusters topic.
  2. 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. See Adjust the cluster version of a cluster for details.
  3. Start all nodes in the cluster, or at least those that will be in the device domains. See Start a cluster node for details.
