Active/Active Configuration with NAS Storage

In the Active/Active configuration below, both Node1 and Node2 are primary LifeKeeper servers for WebSphere MQ resources. Each server is also the backup server for the other. In this example, Node1 protects the NFS mount for queue manager QMGR1. Node2 protects the NFS mount for queue manager QMGR2 as the primary server. Additionally, each server acts as the backup for the other, which in this example means that Node2 is the backup for the queue manager QMGR1 on Node1, and Node1 is the backup for the queue manager QMGR2 on Node2.

Configuration Notes

• The clients connect to the queue manager QMGR1 using the LifeKeeper floating IP 192.168.1.100.

• The clients connect to the queue manager QMGR2 using the LifeKeeper floating IP 192.168.1.101.

• Each server has a dedicated network interface to access the NAS server.

• There are heartbeats configured on each network interface.

• Each queue manager has modified the listener object to contain a unique port number.

• QMGR1 data is located on two NFS exports on the NAS server. The exports are mounted on QMDIR or QMLOGDIR. The NAS server IP is 10.0.0.100.

• QMGR2 data is located on two NFS exports on the NAS server. The exports are mounted on QMDIR or QMLOGDIR. The NAS server IP is 10.0.0.100.
