Abstract

There are included the steps of receiving an operation input for defining a plurality of setting information pieces on a disk subsystem as a command by one operation, storing the defined setting information as a file, and sending the file to the disk subsystem.

Claims

A disk subsystem setting method of setting a first disk subsystem, for which setting information regarding path, logical unit number (LUN) security and logical volume for each volume in disk configuration is undefined using an information processing apparatus connected to the first disk subsystem and a second disk subsystem, for which setting information regarding path, LUN and logical volume for each volume is defined, comprising the steps of:

receiving through an input apparatus of said information processing apparatus a first input to read said undefined setting information of said first disk subsystem from a first memory of said first disk subsystem by use of a file name;

checking whether no logical volume is set in said first disk subsystem, wherein if a result of the step of checking for no logical volume is negative, then a command is not sent to change the setting of said first disk subsystem, otherwise proceeding to a step of creating a logical volume in said first disk subsystem, when a create box has been set through said input apparatus;

changing said undefined setting information based on said defined setting information by creating a same number of logical volume tables for logical volumes in said first disk subsystem as a number of logical volume tables for logical volumes in said second disk subsystem to extract difference information of said defined setting information of said path, LUN security, and logical volume tables and said undefined setting information of said path, LUN security and logical volume tables;
