Smart Assist for Lotus Domino Server
Smart Assist for Lotus® Domino® Server allows you to automatically configure PowerHA® SystemMirror® where Lotus Domino is already configured. There is a cluster present in lotus domino server. PowerHA SystemMirror configuration supports operating systems cluster across the nodes in the cluster.
- PowerHA SystemMirror cluster with active-passive lotus domino configuration (without domino clustering)
- The basic configuration for active-passive operating system clustering is having a IBM® Lotus Domino Server running on Node 1. While Node 2 monitors Node 1 and waits for a failure to occur. When a failure occurs, Node 2 picks up the resources of Node 1 and takes over running the IBM Lotus Domino Server. Node 2 uses the same disk set and the same IP address for the IBM Lotus Domino Server that Node 1 used.
- PowerHA SystemMirror cluster with active-active lotus domino configuration (without domino clustering)
- To run IBM Lotus Domino Server in
an active-active cluster, you must use Domino partitioned servers on the nodes. This
allows each node take over the tasks of the other node while also
maintaining its own tasks.
The basic configuration for active-active operating system clustering is Node 1 and Node 2 each has IBM Lotus Domino Server running in the first partition. The second partition on each node duplicates the resources of the first partition on the other node. Each node has its own disk set, but both nodes have access to both disk sets in case failover occurs. Thus, the nodes monitor each other.
When Node 1 fails, Node 2 picks up the resources of Node 1 and runs the IBM Lotus Domino Server for both nodes. To use an active-active configuration, you must be sure that each node can handle the load of the other node if failover occurs.
- PowerHA SystemMirror cluster with domino clustering
- For a Domino cluster
you can configure either partitioned domino servers or stand alone IBM Lotus Domino Server.
Do not include partitioned servers that are on the same computer in
the cluster. Doing so can cause significant failover and workload
problems if that computer fails.To configure operating cluster for a Lotus Domino cluster consider the following requirements:
- There is no failover on the IBM Lotus Domino Server in the Domino cluster.
- The shared volume groups between the IBM Lotus Domino Server in the Domino cluster is not required as they replicate the data for every few seconds.
