While configuring a new MAIN system in a multisystem node, an error was encountered while attempting to allocate a workspace data set previously used by the old MAIN system of this local node, node-name. Shared DASD and a shared VSAM catalog are recommended for the RRSF workspace data sets due to this operation and when they are not used, the workspace data set must be manually copied from the old MAIN system to this new MAIN system (using the same workspace file name).
