The TARGET command has detected that one or more workspace data sets for node node-name are currently allocated and does not update the workspace data set attributes for node node-name. A node's workspace file attributes are changeable until the files have been allocated, which normally occurs during processing of a DORMANT/OPERATIVE keyword. After the files have been allocated, the file attributes may not be changed. If SYSNAME information is present in this message, the node node-name is a multisystem node.
