Hi all, As you know in most environments, clusters operate in an active/passive mode – the passive server providing hardware redundancy. In a DR situation, generally only one of the two servers are restored. However, since we operate in active/active mode, required to support the work load, both servers must be recovered. Restoring to unlike hardware (Dell to HP) presents some additional challenges. The recommended approach is to build the systems from scratch. However, based on comments during our weekly meeting that installing the application from scratch would take days, and so is not feasible. Currently we are looking at a software known as Double-Take which is mighty expensive and not sure if this would overcome the disk signature problem. If anybody has any ideas or has been in a similar situation please share your ideas. Thanks in advance.
