Setup symmetry and MSCS

When an application switches from one node to the other it must behave in the same way, regardless of node. The best way of ensuring this is to make the environments identical.

If we can, set up a cluster with identical hardware, operating system software, product software, and configuration on each computer. In particular, ensure that all the required software installed on the two computers is identical in terms of version, maintenance level, SupportPacs, paths and exits, and that there is a common namespace (security environment) as described in MSCS security.
