Abstract: A computer acquires first connection information related to a path connecting a host computer and a local storage, and acquires second connection information related to a path connecting storage systems. The computer creates route management information based on the connection information. The route management information is information related to a plurality of routes. A single route is configured from two or more nodes connected in series and an inter-node path. The start node of the two or more nodes is a host computer, and the other node of the two or more nodes is a storage system. Based on the route management information, the computer selects, as the host computer for executing a remote scan, the host computer that is the start node of the optimum route from among the plurality of routes having the scan-targeted remote storage as the end node.

Abstract: Provided is a load balancing method for a computer system having one or more host computers, one or more storage systems, and a management computer. Each storage system has a physical disk for storing data that is requested by the host computer to be written, and a disk controller for controlling the physical disk. The load balancing method is characterized in that the storage system provides a storage area of the physical disk as one or more logical units to the host computer, and that the management computer calculates the processing amount of a component passed by a logical path, and refers to the calculated processing amount of the component when distributing, to the logical path, I/O issued from the host computer. Accordingly, it is possible to choose which path to use for access appropriately.

Abstract: An s-triazine derivative with at least one asymmetric carbon atom of the general formula: ##STR1## wherein R.sub.1 and R.sub.2 are different and are each hydrogen, an alkyl, an aralkyl or phenyl; R.sub.3 is an alkyl, a cycloalkyl, an aralkyl or phenyl; and X and Y are the same or different: ##STR2## wherein R.sub.4, R.sub.5,R.sub.7, R.sub.8 and R.sub.9 are the same or different and are each hydrogen, an alkyl, a cycloalkyl, an aralkyl or phenyl; and R.sub.6 is an alkyl, a cycloalkyl, an aralkyl or phenyl, and a gas chromatographic method for the resolution and analysis of the mixture of enantiomers having an --NH-- group linked to an asymmetric carbon atom, or to an atom in .alpha.-position with respect to an asymmetric carbon atom, comprising using said derivative as an optically active stationary phase for the gas chromatography.
