Migration procedure illustrated with a sample example

This section describes a step-by-step procedure to migrate a VCS cluster running Apache Web server to an SG/LX cluster.

The VCS cluster has two systems: hnode and pnode running Red Hat 6.1 and uses three SCSI-3 based coordination point

disks as membership arbitration mechanism. There is a single channel bonded heartbeat network (10 .25.1.0) between

the nodes.

The Apache Web server application is deployed as a failover service group: “apache_svcgrp” using VCS Apache agent. The

Apache Web server is installed and configured locally on both nodes of the cluster (that is, the Apache configuration file,

process ID file, and the binary that reside locally on both the nodes of the cluster). The Apache document root

(/mount/vg_apache/apache) resides on a shared disk (/dev/vgapache/lvol0) accessible from both the nodes.
