SYSTEM AND METHOD FOR PROVIDING A COMPUTER STANDBY NODE
First Claim
1. An apparatus for providing a computing environment in a computing system, the apparatus comprising:
- a first node capable of supporting a production computing environment and having first disk storage;
a second node capable of supporting a second operational computing environment, independent of the production computing environment, and having second disk storage;
an operations server that manages the first and second node and that can switch the production computing environment from the first node to the second node; and
a communications link between the first node, the second node, and the operations server;
wherein the operations server can cause the second node to take over the production computing environment from the first node upon a failure of the first node by providing the second node with access to the first disk storage and rebooting the second node from the first disk storage.

Abstract
An apparatus for providing a computing environment in a computing system includes a first node, a second node, an operations server, and a communication link. The first node is capable of supporting a production computing environment and 5 has a first disk storage. The second node is capable of supporting a second operational computing environment, independent of the production computing environment and has a second disk storage.
A method of switching a production computing environment from a first node, having a first disk storage, to a second node in the event of a failure on the first 15 node includes determining if the first node had a failure and if the first node had a failure: reassigning ownership of the partition definition to the second node; restoring communications configuration on the second node; and booting the second node from the first disk storage.
