Abstract

An improved method and system for initializing the logical units (LUs) in a Gateway between an SNA network having a mainframe host computer and another network. An activation procedure derives the Table of Boundary LUs on the mainframe host computer by noting the device logical unit numbers within the set of `Activate Logical Unit` (ACTLU) SNA Request Units. If the mainframe host computer includes an LU in its Table of Boundary LUs, then the activation procedure creates a corresponding LU in the Gateway. The activation procedure also marks each of the created LUs in the Gateway as active. The newly created LUs are then added to the resource pool of LUs available to the network. Additional aspects include a method for assigning a logical unit type to an LU based upon whether a Bind request is received from the mainframe host computer within a certain amount of time after sending a positive sense code to the mainframe host computer.
